persistent fog



Fog has been persistent today in the Sacramento Valley. These two photos were taken from my back porch looking west. The top photo was taken earlier this year on a clear day. You can see the snow-capped Coast Range and the valley floor. The photo below was taken earlier today, with the persistent fog bank in the valley. The two photos are a comparison and to give one a perspective on how thick fog can get in the valley. Fog continues to linger currently, keeping temperatures in Chico stuck in the 40s. Fog will reform tonight (if it ever burns off today) and become dense overnight, so be careful if traveling during the early morning hours. The fog should be confined to the Southern Sacramento Valley by Monday, keeping it out of Chico. Temperatures under sunny skies will warm into the mid 60s by later this next week. Here are the details from the National Weather Service:

Tonight: Areas of dense fog after 10pm. Otherwise, mostly cloudy, with a low around 40. Calm wind becoming northeast around 5 mph.

Sunday: Areas of dense fog before 10am. Otherwise, partly sunny, with a high near 61. Light and variable wind.

foggy mornings, sunny afternoons

I hope everyone had a wonderful Thanksgiving. It was a gray and somewhat wet day today, as Chico saw .44 of an inch of rain. If you're getting an early start on Black Friday (some stores in Chico will open at midnight tonight), be very careful when driving. Fog is thick in some areas, with visibilities down to one mile or less, particularly in the foothills right now. This will be the weather pattern the next few days, as the valley will see areas of dense fog in the overnight and early morning hours, followed by afternoon sunshine. High temperatures the next several days will be in the low to mid 60s as strong high pressure will dominate our weather. Here are the details specifically for Chico from the National Weather Service:

Tonight: A 20 percent chance of rain. Mostly cloudy, with a low around 41. Light east southeast wind.

Friday: Mostly sunny, with a high near 59. Calm wind becoming northwest between 5 and 8 mph.

Friday Night: Partly cloudy, with a low around 40. North northwest wind between 3 and 6 mph.

Saturday: Mostly sunny, with a high near 62. Calm wind.

Saturday Night: Areas of dense fog after 10pm. Otherwise, partly cloudy, with a low around 42. Calm wind.

Sunday: Areas of dense fog before 10am. Otherwise, mostly sunny, with a high near 65.

Sunday Night: Mostly cloudy, with a low around 42.

Monday: Partly sunny, with a high near 65.

Monday Night: Partly cloudy, with a low around 40.

Tuesday: Mostly sunny, with a high near 65.

Tuesday Night: Partly cloudy, with a low around 41.

wet Thanksgiving, followed by spring-like weekend

It looks like this storm and its associated cold front are weakening, after pounding parts of the Pacific Northwest with strong winds and heavy rain the past two days. Portland, Oregon received nearly two and a half inches of rain in just over 24 hours! Parts of the Seattle area received over an inch of rain in just a few hours early this morning. Fortunately (or unfortunately, if , like me, you love stormy weather) we won't see all of that heavy rain and high winds here. Still, expect Thanksgiving to be wet for most of the northern Sacramento Valley and adjacent foothills the next 24 hours. Snow levels will be high- mainly above pass level. Just a few inches of snow is expected above 6000 feet through tomorrow night. This weekend looks spectacular, with sunny skies and spring-like temperatures in the mid to upper 60s in Chico. Enjoy as you go out and about getting your Christmas shopping done! Here is Chico's seven day forecast from the National Weather Service:

Today: A 30 percent chance of rain, mainly after 4pm. Mostly cloudy, with a high near 58. Southeast wind between 10 and 13 mph. New rainfall amounts of less than a tenth of an inch possible.

Tonight: Rain, mainly after 10pm. Low around 42. Southeast wind between 10 and 13 mph. Chance of precipitation is 90%. New rainfall amounts between a tenth and quarter of an inch possible.

Thanksgiving Day: Rain, mainly before 4pm. High near 55. Southeast wind around 9 mph. Chance of precipitation is 80%. New rainfall amounts of less than a tenth of an inch possible.

Thursday Night: A 30 percent chance of showers, mainly before 10pm. Mostly cloudy, with a low around 40. East northeast wind between 3 and 6 mph. New rainfall amounts of less than a tenth of an inch possible.

Friday: Partly sunny, with a high near 59. North northwest wind around 6 mph.

Friday Night: Partly cloudy, with a low around 39.

still on track for a stormy Thanksgiving

Today has been fairly quiet after a rainy and breezy (at times) weekend. Chico received well over a half an inch of rain between Saturday evening and Sunday afternoon. The break from the rain continues tomorrow and for most of Wednesday before a powerful jet stream steers a very wet and windy storm our way. Expect rain and breezy conditions for the valley (including Chico) Wednesday night and Thursday (Turkey Day). For the Sierra, snow levels will initially start out high Wednesday evening- 6000 feet. By Thursday morning, snow levels will drop to 4000 feet. Right now there still is no clear forecast of snowfall tallies, but expect at least six inches of snow above pass level by Thursday afternoon. As for rainfall totals, I'm going to guess anywhere from .50 to over one inch for most valley locations. Black Friday looks drier and calmer as the storm exits our area. The weekend looks very nice, with seasonal temps and sunny skies. Here are the specifics for Chico from the National Weather Service:

Tonight: A 20 percent chance of rain. Mostly cloudy, with a low around 40. East southeast wind around 10 mph. New rainfall amounts of less than a tenth of an inch possible.

Tuesday: A 20 percent chance of rain. Partly sunny, with a high near 59. South southeast wind between 11 and 13 mph, with gusts as high as 20 mph.

Tuesday Night: Mostly cloudy, with a low around 42. Southeast wind between 8 and 10 mph.

Wednesday: A 20 percent chance of rain. Mostly cloudy, with a high near 57. Southeast wind between 7 and 13 mph, with gusts as high as 18 mph.

Wednesday Night: Rain. Low around 39. Chance of precipitation is 80%.

Thanksgiving Day: Rain. High near 55. Chance of precipitation is 80%.
