the "lack of rain" season continues

Well, Chico will finish December with only .26" of rain, making it the second driest December on record. And it looks like there is no significant rain in the forecast for at least the next seven days. High pressure will strengthen over Northern California, allowing high temperatures to climb into the lower to mid 60s the next few days. Overnight lows will remain chilly- mainly in the 30s. This dry air allows the huge temperature diurnal (the difference between the overnight low and daytime high temperature). We still have plenty of winter left, but this lack of rainfall is concerning. Also, if you're out and about celebrating the new year, expect dry conditions and temps hovering in the mid 40s around midnight tonight. Here is the seven day forecast for Chico from the National Weather Service:

Today: Mostly sunny, with a high near 61. South wind 7 to 9 mph becoming west.

Tonight: Partly cloudy, with a low around 35. North northeast wind around 7 mph.

New Year's Day: Mostly sunny, with a high near 64. North northwest wind around 6 mph.

change in the weather

From the National Weather Service:

AFTER A PERIOD OF DRY WEATHER OVER INTERIOR NORTHERN CALIFORNIA...A
COLD FRONT WILL SWEEP ACROSS THE AREA BRINGING RAIN...MOUNTAIN SNOW
AND WIND TO THE REGION. HOWEVER...IT DOES NOT LOOK LIKE A LOT OF
RAIN AND SNOW.

MOST OF THE PRECIPITATION WILL FALL NORTH OF THE INTERSTATE 80
CORRIDOR WITH THE SHASTA COUNTY MOUNTAINS RECEIVING MOST OF THE
PRECIPITATION. RAINFALL AMOUNTS OF AN INCH OR MORE ARE FORECAST FOR
THE AREA...WITH AMOUNTS TAPERING TO A FEW TENTHS OF INCH OVER THE
COASTAL MOUNTAINS AND SIERRA NEVADA NORTH OF INTERSTATE 80.

SNOW LEVELS WILL BE RELATIVELY HIGH...ABOVE 5000 FEET OVER THE
SHASTA COUNTY MOUNTAINS TO AROUND 7000 FEET OVER THE INTERSTATE 80
CORRIDOR ON FRIDAY WHEN MOST OF THE PRECIPITATION IS EXPECTED.
SNOWFALL AMOUNTS GENERALLY FROM 2 TO 4 INCHES ARE FORECAST...WITH AN
INCH OR TWO IN THE INTERSTATE 80 AND HIGHWAY 50 CORRIDOR. ALTHOUGH
SNOW LEVELS ARE LIKELY TO LOWER FRIDAY NIGHT...LITTLE PRECIPITATION
IS EXPECTED OVER THE AREA AS THE WEATHER SYSTEM WILL QUICKLY MOVE
THROUGH THE AREA.

SOUTHWEST WINDS FROM 20 TO 30 MPH WITH GUSTS TO 50 MPH OR HIGHER ARE
EXPECTED OVER THE HIGHER MOUNTAINS. THE WINDS WILL INCREASE
TONIGHT...AND DECREASE BY FRIDAY EVENING.


Again, this storm does not have much moisture to work with, and it's a quick mover. Once this storm passes, expect a return to sunny, dry and mild weather. Look for high temps near 60 degrees for this weekend, and lows in the 30s to around 40 degrees.

possible rain for Friday

Today was mainly overcast and mild, with highs reaching into the mid 50s. There's only a slight chance of rain the next 36 hours, but a stronger storm system will affect the area by Friday. Again, not a lot of rain is expected, with generally a tenth of an inch or less possible. There may be some gusty southerly winds accompanying this storm, as well. By this weekend, expect dry weather for your New Year's Eve plans. It will be chilly as you're out and about New Year's Eve, with temperatures in the 30s and 40s. Bundle up! Here's the specific seven day forecast for Chico from the National Weather Service:

dry December

It looks like December 2011 will go down as the second driest on record for Chico. Just .25" has fallen since December 1st. With only scant chances of rain for this week, the prospects don't look good for clawing out of our rainfall deficit. We still have a ways to go in the rainy season (the rainy season usually winds down in April), so hopefully we can still catch up. It looks as though the Pacific Northwest will get the lion's share of the precipitation this week. Stubborn high pressure over California will shunt all of the stormy weather to our north. Plus, the jet stream is aimed right at Oregon and Washington, and the storm path rides along the jet stream. Translation: don't look for much rain in our area for awhile. Here is the not-so-wet forecast for Chico from the National Weather Service:

Tonight: Areas of frost after 10pm. Otherwise, mostly cloudy, with a low around 31. Light north northwest wind.

Tuesday: Areas of frost before 10am. Otherwise, mostly cloudy, with a high near 56. Calm wind becoming northwest around 5 mph.

Tuesday Night: A 20 percent chance of showers. Cloudy, with a low around 39. Calm wind becoming east around 5 mph. New rainfall amounts of less than a tenth of an inch possible.

Wednesday: A 30 percent chance of showers, mainly after 10am. Cloudy, with a high near 59. Calm wind. New rainfall amounts of less than a tenth of an inch possible.

Wednesday Night: A 20 percent chance of showers. Mostly cloudy, with a low around 42. Light east wind.

Thursday: A 20 percent chance of showers. Mostly cloudy, with a high near 58.

Thursday Night: A 20 percent chance of showers. Mostly cloudy, with a low around 39.

Friday: A slight chance of rain. Mostly cloudy, with a high near 58.

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

Saturday: Partly sunny, with a high near 58.

Saturday Night: Mostly cloudy, with a low around 38.

Nice holiday weather

It has been cold the past few mornings in Chico, with temperatures plummeting into the mid 20s. The Hard Freeze Warning that has been in effect the previous two nights in the Sacramento Valley is in effect for a third night, until 9am tomorrow. Look for lows Christmas morning around 27 degrees in Chico, and possibly colder temps west of the city. High temperatures the next few days will be the same as they have been the past few days- mid 50s. That's actually right about where we should be for this time of year. Finally, I'll end this blog entry by wishing everyone a safe and happy holiday season- Merry Christmas, Happy Hanukkah, and Happy Kwanzaa. Here's Chico's forecast for the next seven days from the National Weather Service (notice the chances of rain beginning midweek next week- fingers crossed!):

Is it December or April?

Looking at the current temperature (67 degrees in Chico), one would think Mother Nature was confused about which month it is. Light northwesterly winds, low humidity and ample sunshine are combining to cause the temperature to soar to nearly fifteen degrees above normal. Meanwhile, 90 miles to our south in Sacramento, fog has been persistent much of the day and temps there have been held into the 50s this afternoon. The dry, mild weather continues through at least the middle of next week. December 2011 may go down as one of the driest months in Chico's weather history if this trend continues. Hopefully we'll get more rain before the end of the year. Here's Chico's seven day forecast from the National Weather Service:

Tonight: Patchy dense fog after 4am. Areas of frost after 4am. Otherwise, clear, with a low around 32. Light and variable wind.

Wednesday: Patchy dense fog before 10am. Areas of frost before 10am. Otherwise, sunny, with a high near 59. North northwest wind 5 to 8 mph increasing to between 13 and 16 mph. Winds could gust as high as 28 mph.

Wednesday Night: Clear, with a low around 31. North northeast wind around 8 mph.

Thursday: Patchy fog after 10am. Areas of frost between 10am and 4pm. Otherwise, sunny, with a high near 57. North wind around 7 mph.

Thursday Night: Areas of frost after 10pm. Otherwise, mostly clear, with a low around 32. North northeast wind around 6 mph.

Friday: Areas of frost before 10am. Otherwise, mostly sunny, with a high near 57.
