Forecast

January 2, 2022/report

January 2, 2022

Definitely a chilly night, as expected, with widespread upper 20s and lower 30s. considering the amount of rain we’ve received over the past few weeks, the air mass on the valley floor is fairly dry due to a weather system which moved through the Great Basin day before yesterday. The air aloft has warmed considerably. The freezing level this morning over Vandenberg was 10,300 feet compared to the level yesterday at this time when the level was 4,500 feet. Still, this time of year with short days and a low sun angle can make it difficult to remove a particular air mass.

 

In the big picture, upper level high pressure is now governing the western 1/3 of the US while arctic air plunges southward into the middle of the country. A weak trough of low pressure will unsuccessfully move through the high Tuesday. It will spread light precipitation down to a Bay Area/Sacramento line.  The high will regenerate Wednesday through Thursday night then yet another trough will try to penetrate the high. Like its predecessor, though, it will have difficulty moving southward. It’s possible a few light showers could reach as far south as Fresno County Friday, but for now we must file this one in the small chance category.

 

Medium range models indicate we will move back into the blocking ridge pattern with the storm track moving back into the Pacific Northwest with California remaining dry under that dome  of high pressure. Polar air masses will continue to affect the nation’s midsection and points eastward.

 

Forecast: Mostly clear skies through Monday night with areas of night and morning fog and low clouds. Variable cloudiness Tuesday and Tuesday night with patchy morning fog. Mostly clear Wednesday through Thursday night with areas of night and morning fog and low clouds. Variable cloudiness Friday through Sunday with patchy night and morning fog and low clouds. Mostly clear Sunday with areas of night and morning fog and low clouds.

Two Week Outlook:  January 7 through January 13: This model has reverted to a dry forecast with above average temperatures.

 

January:  This model doesn’t really indicate a trend that would favor above or below precipitation. The active storm track in the Pacific Northwest will continue. Both temperatures and precipitation should be close to seasonal averages.

 

January, February, March: The trend of below average temperatures of late continues on the 90 day forecast which indicates temperatures will be slightly below average. Below average precipitation is anticipated over the Desert Southwest and the southern half of California with near average precipitation from Fresno County north.

 

Wind Discussion: Winds will be generally at or less than 6 MPH with periods of near calm conditions through Wednesday.

 

Rain:  There is a small chance of a few light showers from mainly Fresno County north Friday and Friday night. However, models are tracking the possible rain line a bit further north. Outside of that, we’ll go with a dry forecast for the next week to ten days.

Frost: Both Lindsay and Porterville dipped down to 27 last night for the cold spots. All other locations were in the upper 20s and lower 30s. high resolution short term modeling indicate dew points this afternoon will range in the mid to upper 30s, meaning the valley floor’s air is relatively dry. This will allow another night of upper 20s and lower 30s with isolated river bottom unprotected locations possibly dipping into the mid 20s. warmer air is moving in above the valley floor as freezing levels have jumped up to 10,000 feet. A weak weather system will try to move in here unsuccessfully Tuesday. However, dew points currently in the mid to upper 30s should rise into the 40s, meaning a slow moderation in overnight low temperatures will begin Tuesday morning. Readings will stay above freezing for Wednesday and beyond as mild air aloft slowly mixes down to the surface. Temperatures tonight at 34 feet should be anywhere from 5 to 8 degrees warmer under a nice warm air inversion,
