calmer but colder

This latest storm brought Chico an inch and a quarter of rain, along with winds gusting to over 30 mph late last evening. Today has been mainly sunny, with brisk northwest winds gusting to 35 mph. It's forecast to get colder over the next few days as a piece of Arctic air plunges down from western Canada. High temps will be mainly in the 40s with lows in the 30s. Bundle up if you're heading out for New Year's celebrations on Friday night; temps will be in the lower to mid 30s. Temps should warm back to normal levels by Sunday. Other than a slight chance of rain this weekend, it'll be mainly dry over the next several days- a much- deserved break from all the storminess! Here's the detailed forecast for Chico from the National Weather Service:

Tonight: Mostly cloudy, with a low around 31. North northwest wind between 8 and 14 mph.

Thursday: Partly sunny, with a high near 50. Northwest wind between 3 and 6 mph.

one storm exits, another one on the way

The parade of storms continues for Northern California. The most recent storm we experienced (that is now departing) gave Chico over an inch of rain and wind gusts near 30 mph. Temps have been mild this weekend, with highs mainly in the low to mid 50s, right about where we should be. However, another storm is on its way, developing currently over the Gulf of Alaska, and should arrive by Tuesday. Storms that originate there are usually colder storms, and this one will be no exception. Prepare for lower snow levels, down to 2000 feet by Wednesday in the Sierra Nevada foothills. A couple of inches of snow are possible down to that elevation, while nearly two feet of snow are possible above 5000 feet in the Sierras between Tuesday and Wednesday. In the valley, expect anywhere from .75" and 1.25" of rain. Right now the National Weather Service isn't saying much about wind speeds, but I expect at least 25 mph gusts in the valley and nearly 50 mph gusts in the mountains. Thursday and Friday look fairly calm, but cold, with highs only in the 40s in Chico. It looks like another weak system will pass through on New Year's Day, bringing with it a chance of showers. Colder than normal temps will last through next weekend. Here's the detailed forecast for Chico from the National Weather Service:

Tonight: A slight chance of sprinkles before 10pm. Mostly cloudy, with a low around 38. South southeast wind between 3 and 8 mph.

Monday: Partly sunny, with a high near 55. Southwest wind around 6 mph becoming calm.

Monday Night: A 30 percent chance of rain. Mostly cloudy, with a low around 39. North northwest wind around 5 mph becoming calm.

Tuesday: Rain. High near 53. Calm wind becoming south southeast around 6 mph. Chance of precipitation is 80%.

Tuesday Night: Rain. Low around 43. Chance of precipitation is 90%.

Wednesday: Showers likely. Partly sunny, with a high near 51. Chance of precipitation is 60%.

Wednesday Night: A chance of showers. Mostly cloudy, with a low around 32.

Thursday: A slight chance of showers. Partly sunny, with a high near 45.

Thursday Night: Partly cloudy, with a low around 29.

Friday: Mostly sunny, with a high near 45.

Friday Night: A slight chance of showers. Mostly cloudy, with a low around 35.

New Year's Day: A chance of showers. Mostly cloudy, with a high near 45.

Merry Christmas!

For everyone celebrating today- Merry Christmas! Unfortunately, the weather won't be too Christmas-y in Chico this year, what with the rain and wind. It's probably best to stay indoors today. More from the National Weather Service:

GUSTY WINDS...RAIN AND MOUNTAIN SNOW EXPECTED TODAY...

A FAST MOVING COLD FRONT WILL SPREAD MORE RAIN AND SNOW ACROSS
NORTHERN CALIFORNIA TODAY AND TONIGHT. SNOW WILL BECOME STEADY
ABOVE 4500 FEET LATE THIS MORNING ALONG THE COASTAL RANGE...AND
OVER THE SHASTA COUNTY MOUNTAINS BY EARLY AFTERNOON. SNOW WILL
MOVE INTO THE MOUNTAINS SURROUNDING THE BURNEY BASIN BY LATE
AFTERNOON.

AT THIS TIME IT LOOKS LIKE THE CENTRAL VALLEYS WILL SEE STEADY
RAINFALL THIS AFTERNOON AND EVENING. SOUTH TO SOUTHEAST WINDS WILL
INCREASE TO 15 TO 25 MPH LATER THIS MORNING. A COLD FRONT WILL
MOVE THROUGH LATER THIS AFTERNOON. WIND GUSTS TO 35 MPH ARE
POSSIBLE JUST AHEAD OF THE FRONT. THUNDERSTORMS MAY OCCUR IN
UNSTABLE AIR ALONG AND JUST BEHIND THE COLD FRONT LATE THIS
AFTERNOON AND THIS EVENING.

TOTAL RAINFALL AMOUNTS WILL RANGE BETWEEN THREE QUARTERS OF AN INCH
TO AN INCH FOR THE CENTRAL VALLEYS. SIMILAR AMOUNTS ARE EXPECTED
IN THE FOOTHILLS. HIGHER RAINFALL AMOUNTS ARE POSSIBLE IN THE
SHASTA DRAINAGE AREA...BUT THE FAST MOVING NATURE OF THE FRONT
WILL LIMIT OVERALL RAINFALL.

PERIODS OF MODERATE TO HEAVY SNOW ARE POSSIBLE OVER THE HIGHER
PEAKS OF THE COASTAL MOUNTAINS THIS EVENING. SNOW LEVELS WILL
DROP TO 2500 TO 3500 FEET EARLY SUNDAY MORNING ALONG THE COASTAL
RANGE AND SHASTA COUNTY MOUNTAINS AS SNOW TAPERS OFF TO SCATTERED
SNOW SHOWERS. LITTLE ACCUMULATION IS EXPECTED AT THESE LOWER ELEVATIONS.

SOUTH TO SOUTHWEST WIND GUSTS IN EXCESS OF 45 MPH MAY CAUSE
REDUCED VISIBILITY OVER MOUNTAIN PASSES SUCH AS MENDOCINO PASS
TONIGHT. TRAVELERS HEADING NORTH ON INTERSTATE 5 MAY ENCOUNTER
WINTER WEATHER SUNDAY MORNING AS THEY HEAD NORTH OF SIMS.

HAZARDOUS BACK COUNTRY TRAVELING CONDITIONS MAY EXIST SUNDAY.

IF YOU PLAN TO TRAVEL THIS HOLIDAY WEEKEND...BE PREPARED FOR UNSETTLED
WEATHER. IF TRAVELING TO THE MOUNTAINS...CARRY TIRE CHAINS AND
EMERGENCY SUPPLIES AND CHECK THE LATEST WEATHER AND ROAD REPORTS
BEFORE DEPARTURE.

soggy Christmas

The weather forecast has changed somewhat over the past 24 hours. Instead of stormy conditions tomorrow night into Sunday, now most of the heavier rain and breezy conditions will occur Christmas Day. The rain will taper to showers by Saturday night and linger into Boxing Day (Canadians know what I'm referring to; it's the day after Christmas for us Americans). Another cold front arrives late Tuesday, ushering in colder air from (I'm assuming) Canada. Computer models differ on the timing and severity of the cold weather, so, again, check back for updates. With this next storm, expect up to an inch of rain in some valley locations, while 5-10 inches of snow are possible in the Sierras above 4000' through Sunday evening. Over a foot of snow is likely above 5000'. Be careful if visiting friends or relatives this weekend in the Sierras; prepare for inclement weather. Here are the details for Chico from the National Weather Service:

Tonight: A 10 percent chance of rain after 4am. Mostly cloudy, with a low around 40. East southeast wind around 6 mph.

Christmas Day: Rain, mainly after 10am. High near 51. South southeast wind between 10 and 15 mph, with gusts as high as 18 mph. Chance of precipitation is 80%.

Saturday Night: Showers, mainly before 10pm. Low around 42. South southeast wind between 15 and 21 mph, with gusts as high as 26 mph. Chance of precipitation is 100%.

Sunday: Showers likely. Mostly cloudy, with a high near 51. South southeast wind between 13 and 15 mph, with gusts as high as 20 mph. Chance of precipitation is 60%.

Sunday Night: A 10 percent chance of rain after 4am. Mostly cloudy, with a low around 41.

MOUNTAIN SNOW POSSIBLE CHRISTMAS MORNING. HEAVIER RAIN AND
MOUNTAIN SNOW ARE EXPECTED BY SATURDAY NIGHT AND SUNDAY MORNING AS
THE MAIN FRONTAL SYSTEM MOVES THROUGH. SHOWERS ARE EXPECTED TO
CONTINUE THROUGH THE DAY SUNDAY ESPECIALLY OVER THE MOUNTAINS SO TRAVEL
DURING THE SECOND HALF OF THE WEEKEND IS LIKELY TO BE IMPACTED AS WELL.

IT IS TOO EARLY TO TELL JUST HOW MUCH PRECIPITATION WILL BE
GENERATED FROM THIS SYSTEM. CURRENT PROJECTIONS HOWEVER INDICATE
AN INCH OR MORE OF RAIN COULD FALL ON THE VALLEY FLOOR OVER THE
WEEKEND...WHILE THE MOUNTAINS COULD SEE ONE TO TWO FEET OF SNOW
ABOVE 7000 FEET BY MONDAY MORNING.

MODERATE SNOW LEVELS ARE EXPECTED WITH THIS STORM. THEY WILL RANGE

OF NORTHERN CALIFORNIA WILL LIKELY BE IMPACTED WITH CHAIN CONTROLS
AND TRAVEL DELAYS SATURDAY NIGHT INTO SUNDAY AFTERNOON. PERIODS OF
HEAVY SNOW AND STRONG WINDS MAY LEAD TO WHITE-OUT CONDITIONS AT TIMES.

IF YOU PLAN TO TRAVEL THROUGHOUT NORTHERN CALIFORNIA THIS HOLIDAY
WEEKEND...BE PREPARED FOR UNSETTLED WINTER WEATHER. IN THE
MOUNTAINS...CARRY TIRE CHAINS AND EMERGENCY SUPPLIES AND CHECK THE
LATEST WEATHER AND ROAD REPORTS BEFORE DEPARTURE.

winter weather

Well, winter weather as it pertains to our region, anyway. More valley rain and mountain snow is on the way for tonight as another storm system crashes ashore from the Pacific. This storm will be a bigger headache for Southern California than for us here in Northern California. Here, expect some nuisance rain and snow showers for the mountains above 3500 feet. This storm will move out quickly tomorrow, leaving behind some scattered light rain showers. We get a bit of a break Thursday and Friday before another storm impacts our area on Christmas Day and Sunday. It's still too early to tell how big of an impact we'll get from this weekend's storm, so check back as I make updates. For now, enjoy the wet and winter-like weather. Here's Chico's seven day forecast from the National Weather Service:

gray, dreary weather

Tomorrow is the first day of winter in the Northern Hemisphere, and it already looks and feels like it here in Northern California. The high temperature in Chico today struggled to get above 50 degrees, and it's been raining off and on throughout the day. There were some brief sunny breaks earlier this morning, but currently the showers are falling, and temps are stuck in the 40s. This pattern is expected to continue over the next several days, with the next major storm due Wednesday, followed by an even stronger storm on Christmas day. In fact, this entire weekend looks stormy, and we may see more flooding rains for both Saturday and Sunday. As usual, check back for updates, as this may change. For now, here's the latest forecast for Chico from the National Weather Service:

Tonight: Showers likely. Mostly cloudy, with a low around 43. Southeast wind between 13 and 15 mph. Chance of precipitation is 70%.

Tuesday: A 50 percent chance of showers. Cloudy, with a high near 53. Southeast wind around 10 mph.

here we go again

I was awoken (awakened?) by the sound of heavy, wind-whipped rain beating against my sliding glass door, so I thought I would check current weather conditions. A wide swath of moderate to occasional heavy rain is streaming over the Sacramento valley currently. This is courtesy of a second cold front pushing through the region, which will also bring gusty winds. The National Weather Service has posted another Wind Advisory for the area beginning at 8 am this morning and ending at 4 pm this afternoon. The Flood Advisory is still in effect until 1:45 pm today for small stream and urban flooding. Looking ahead towards the upcoming week, it looks like rain will stick around, exacerbating the flood potential. If you live near a creek or stream, especially in the valley, keep an eye on those water levels and be prepared to move to safer ground. Meanwhile, a Winter Storm Warning has been issued for the Sierra Nevada and Lassen Volcanic Park area through tomorrow afternoon. Elevations above 7000 feet (that's you, Lake Tahoe) could get over eight feet of snow (yes, you read correctly; that's not a typo), while the areas around Lassen Park could see 2-3 feet of snow down to around 5000 feet. This is good news, as we need this snowpack to provide us with water for the dry summer months ahead. Here's the soggy forecast for Chico from the National Weather Service:

Today: Rain and possibly a thunderstorm. High near 56. South wind between 10 and 20 mph, with gusts as high as 32 mph. Chance of precipitation is 100%.

Tonight: Showers and possibly a thunderstorm. Low around 43. South southeast wind between 10 and 16 mph, with gusts as high as 24 mph. Chance of precipitation is 90%.

Monday: Showers and possibly a thunderstorm. High near 51. South southeast wind between 17 and 20 mph, with gusts as high as 30 mph. Chance of precipitation is 80%.

Monday Night: Rain likely. Mostly cloudy, with a low around 43. Southeast wind around 13 mph. Chance of precipitation is 70%.

Tuesday: Rain likely. Cloudy, with a high near 53. Southeast wind around 10 mph. Chance of precipitation is 60%.

Tuesday Night: Rain likely. Cloudy, with a low around 42. Chance of precipitation is 70%.

Wednesday Night: A chance of rain. Mostly cloudy, with a low around 39.

Thursday: A chance of rain. Mostly cloudy, with a high near 54.

Friday: A slight chance of rain. Partly sunny, with a high near 54.

Friday Night: A chance of rain. Mostly cloudy, with a low around 39.

Christmas Day: A chance of rain. Mostly cloudy, with a high near 55.

Be safe and stay dry!

more rain coming

Chico has received .80 of rain since yesterday morning, far from the 2 plus inches originally forecasted, but more heavy rain is possible through tomorrow. In fact, the Flood Advisory that was supposed to expire this afternoon has been extended until 1:45 tomorrow afternoon. One to two inches of rain is expected with this next round of storminess beginning late tonight and lasting through tomorrow night. A Winter Storm Warning is in effect until Monday afternoon for the Sierra Nevada above 4500 feet for over two feet of snow. If travelling into the mountains tomorrow, pack a winter survival kit and drive with caution. Rain is predicted to last through Christmas, so keep that umbrella handy for awhile. Here's the detailed forecast for Chico from the National Weather Service:

windy and rainy

A Wind Advisory will go into effect for Chico from 1 am until 7 am tomorrow for winds gusting to over 40 mph. Winds are currently light from the northeast but will shift to the southeast and increase to 15 to 25 mph by late this evening. The strongest winds will occur after midnight tonight. Chico is also under a Flood Advisory until 1:45 pm tomorrow for very heavy rain. The National Weather Service is saying rainfall rates may exceed 1 inch per hour (wow!) after 6 pm this evening. It is going to be a nasty 12-24 hours, so be prepared if you have to be out and about. So far today the rain has been light, totaling about .16 of an inch as of 3 pm this afternoon. More rain is likely Sunday through next Wednesday as a large and powerful storm over the northeastern Pacific Ocean sits and spins, pinwheeling storms right over northern California. Temperatures will stay around seasonable norms for this time of year. Here are the details from the NWS:

Tonight: Rain. The rain could be heavy at times. Temperature rising to around 47 by 5am. Breezy, with a east northeast wind 7 to 10 mph becoming south southeast between 21 and 24 mph. Winds could gust as high as 37 mph. Chance of precipitation is 100%.

flooding potential

Lots to talk about, so let's begin. There is a fairly high probability of urban and small stream flooding this weekend in the Sacramento Valley and surrounding foothills. Winter Storm Watches are posted for both the Coast Ranges and Sierra Nevada mountains for elevations around 3500 feet through this weekend, as well. Winds could gust to 40 mph in the valley and over 50 mph in the mountains, especially on Saturday. This is all due to a strong storm dropping down from the Gulf of Alaska tapping into some moisture streaming across the Pacific Ocean. Rainfall totals between tomorrow and the middle of next week may reach five inches in the valley and six plus inches in the surrounding foothills. There is also a probability that additional storms may impact our area next week, although computer models are not in agreement as to the intensity and timing of the storms. However, if these storms do hit, additional flooding problems may occur. Keep checking back for updates. For now, here's what the National Weather Service is saying for Chico:

Tonight: A slight chance of sprinkles between 10pm and 4am, then rain after 4am. Increasing clouds, with a low around 38. Calm wind becoming east around 5 mph. Chance of precipitation is 20%.

Friday: Rain. High near 50. Light and variable wind. Chance of precipitation is 90%.

Friday Night: Rain. The rain could be heavy at times. Low around 43. Southeast wind 6 to 9 mph increasing to between 18 and 21 mph. Winds could gust as high as 29 mph. Chance of precipitation is 100%.

Saturday: Rain. The rain could be heavy at times. High near 55. Breezy, with a south wind between 18 and 26 mph, with gusts as high as 37 mph. Chance of precipitation is 100%.

Saturday Night: Rain. The rain could be heavy at times. Low around 44. South southeast wind between 13 and 20 mph, with gusts as high as 28 mph. Chance of precipitation is 80%.

Sunday: Rain. The rain could be heavy at times. High near 54. Chance of precipitation is 80%.

Sunday Night: Rain likely. Cloudy, with a low around 42. Chance of precipitation is 70%.

Monday: Rain likely. Cloudy, with a high near 53.

wet pattern setting up

After a couple of dry but foggy days in the Sacramento Valley and surrounding mountains, a wetter pattern looks like it's setting up in our region. Look for the first storm to impact us early tomorrow morning. It's a fast mover, though, and should exit our area by tomorrow night. A Winter Storm Warning is in effect for the Sierra Nevada mountains above 5000 feet beginning at 4 am tomorrow and ending at 10 pm tomorrow night. Eight to twelve inches of snow are possible above that elevation. There will be a brief lull in the activity Wednesday and Thursday, with sunny skies and mild temperatures. However, a series of storms are lined up out in the Pacific Ocean waiting to come onshore by late in the week. We could be looking at a multiple day precipitation event, with heavy rain in the valley and heavy snow in the mountains. It's too early to tell how much precip we'll get and how severe the impacts of these storms will be. Check back over the next several days and I'll have more updated info. For now, here's what the National Weather Service is saying for Chico:

Tonight: Rain likely, mainly after 10pm. Cloudy, with a low around 50. Southeast wind between 5 and 7 mph. Chance of precipitation is 70%.

Tuesday: Rain. High near 55. South southeast wind between 10 and 14 mph. Chance of precipitation is 80%.

more soggy weather

Today was beautiful in Chico, with mainly sunny skies and temps climbing into the lower to mid 60s. The clouds began rolling in late this afternoon, however, ahead of another Pacific storm system that will move in overnight tonight and linger tomorrow. The rain may be moderate to heavy at times tomorrow, and it also could be breezy, so be prepared. This is a warm storm, so no winter weather warnings for the mountains- just a Winter Weather Advisory for accumulations of around 5-10 inches above 4000 feet. Showers linger Thursday and Friday before we have a gorgeous weekend. Sunshine and temps in the low to mid 60s (much like today) will dominate our weekend weather. Here is the latest forecast for Chico from the National Weather Service:

Tonight: Rain likely, mainly after 4am. Mostly cloudy, with a low around 46. Southeast wind between 5 and 9 mph. Chance of precipitation is 60%.

mild and wet storm

Chico received 1.34 inches of rain between yesterday afternoon and this morning. That's a lot of rain! Winds gusted up to 30 mph, as well, so this was a fairly potent storm. It was also a very mild storm, with temps at the time of the rainfall event hovering in the mid 50s. The sun came out late this morning and that pushed temps into the lower 60s by this afternoon. We have another fairly potent storm winding up in the Pacific, and that will affect our weather by the middle of the week. It should be out of here by late in the week, and then the sunshine will return for the weekend. Temps will also warm back up this weekend, with forecast highs expected to be over 10 degrees above normal. It'll feel more like late March than early December. Merry Christmas, indeed. Here's the latest forecast for Chico from the National Weather Service:

Tonight: Partly cloudy, with a low around 44. East northeast wind between 3 and 5 mph.

Tuesday: Mostly sunny, with a high near 60. North northwest wind between 3 and 7 mph.

Tuesday Night: A 40 percent chance of rain after 10pm. Increasing clouds, with a low around 49. Southeast wind between 6 and 11 mph.

Wednesday: Rain. High near 56. Southeast wind around 14 mph, with gusts as high as 20 mph. Chance of precipitation is 90%.

Wednesday Night: Rain likely. Mostly cloudy, with a low around 50. Chance of precipitation is 60%.

update on the storm rolling through

From the National Weather Service:

A VIGOROUS COLD FRONT WILL MOVE THROUGH THE AREA AFTER 10 PM TONIGHT. THUNDERSTORMS ARE POSSIBLE IN THE UNSTABLE AIR MASS ALONG AND BEHIND THE FRONT. THUNDERSTORMS MAY CONTAIN BRIEF HEAVY RAIN... SMALL HAIL AND WIND GUSTS UP TO 40 MPH. THE FRONT WILL MOVE QUICKLY... AND SHOULD BE EAST OF THE AREA BY 4 AM.

REMAIN ALERT TO THE POSSIBILITY OF HEAVY RAIN COMBINING WITH FALLEN LEAVES THAT CREATE NUISANCE TYPE PONDING OF WATER IN LOW LYING AREAS TONIGHT. DO NOT DRIVE THROUGH STANDING WATER. PROTECT OUTDOOR ITEMS FROM GUSTY WINDS IF POSSIBLE.

Chico has already received some heavy rain showers this evening, amounting to nearly an inch of rain. Most of the rain will be out of here sometime after midnight.

wet, but not so windy

It looks like this big storm the National Weather Service was hyping the past few days won't be as big and bad as previously thought. It does look like rain is a (danger- oxymoron ahead) definite possibility, but not so much the wind, at least in the valley. The Sierras could still see some wind gusts to around 30-40 mph, but nothing extreme. Temperatures, for the most part, will be seasonable- mainly 50s for highs and 40s for lows. Again, those temps are for Chico- it'll obviously be colder in the mountains, where snowfall of up to 8 inches is likely above 5000 feet between tonight and tomorrow afternoon. For the bulk of today, there will be some off-and-on showers, but the heavier rain holds off until later tonight. Another storm moves through Wednesday and into Thursday. This second storm doesn't look too ferocious, either. Oh, I forgot to mention the Community Tree Lighting celebration this past Friday evening at the Downtown Plaza. If you were like me and missed it, don't worry. The Christmas Tree at the Plaza will be lit up every night through Christmas. When the weather is nice, and if you happen to be downtown in the evening, go check it out. Here's Chico's seven day forecast from the NWS:

Today: A 50 percent chance of showers. Areas of fog before 10am. Otherwise, cloudy, with a high near 56. Northeast wind between 3 and 9 mph.

Tonight: Rain, with thunderstorms also possible after 10pm. Low around 44. East wind 6 to 8 mph becoming south. Chance of precipitation is 90%.

Monday: A 30 percent chance of showers. Mostly cloudy, with a high near 54. South southeast wind between 9 and 13 mph.

Monday Night: Mostly cloudy, with a low around 39. South southeast wind at 7 mph becoming north northeast.

Tuesday: Mostly cloudy, with a high near 53. North wind around 6 mph becoming east southeast.

Tuesday Night: A 40 percent chance of showers. Cloudy, with a low around 41.

Wednesday: Showers likely. Cloudy, with a high near 55. Chance of precipitation is 70%.

Wednesday Night: A chance of rain. Cloudy, with a low around 46.

Thursday: A chance of rain. Cloudy, with a high near 59.

MORE STORMY WEATHER ON THE WAY SUNDAY AND SUNDAY NIGHT...

where's the rain?

Where's the rain? You may be wondering that (and you're not alone; I've had two people ask me that today); it's on its way- mainly overnight tonight through tomorrow. There are no Special Weather Statements or weather warnings out currently, so I'm assuming this storm is fairly benign. Other than some light rain, I don't see much wind or heavy snow happening the next couple of days. Temps will be fairly seasonable, with highs in the mid 50s and lows in the upper 30s/ lower 40s. The weather for this weekend looks rather uncertain at this point; I'd keep any outdoor plans, but have a Plan B just in case. Here are the details for Chico from the National Weather Service:

Tonight: Rain, mainly after 4am. Low around 44. North wind around 6 mph becoming calm. Chance of precipitation is 80%.

Thursday: Rain, mainly before 10am. High near 54. Calm wind becoming east southeast between 4 and 7 mph. Chance of precipitation is 80%.
