UPDATE
Air Quality Section Updated



KEY MESSAGES
1. Well below temperatures will prevail today before rebounding early this week.

2. A disturbance will continue over Central California, resulting in a chance for rain through this afternoon with snow in the Sierra Nevada and Kern County Mountains above 5,000 feet.

3. A few strong thunderstorms may develop this afternoon and evening, mostly over the valley portion of Kern County.

4. A significant warming trend is forecast to extend through Thursday, then temperatures are expected to remain steady through next weekend.

DISCUSSION
The upper level trough that brought the cold front through the area yesterday is expected to move out of the area by tomorrow.
There is still the possibility (15-20%) for a few strong thunderstorms this afternoon has the clouds move off and the ground begins heating. Though these storms are expected to mostly be in the valley portions of Kern County and are not expected to form north of Tulare County. There may also be lingering snowfall in the mountains above 5,000 feet through the afternoon.

As the trough moves away, ridge-building will begin, resulting in calmer weather and rising high temperatures, beginning on Tuesday. A significant warming trend from Tuesday through Thursday will increase afternoon highs 6-10 degrees above normal for this time of year. This will be a marked difference when compared to today expected highs, which will be more than 10 degrees cooler than normal. Here are the probabilities for select locations in the valley seeing high temperatures of 85 degrees or higher on Thursday:

Fresno: 56% Visalia: 46% Hanford: 36% Lemoore: 36% Delano: 26% Bakersfield: 21% Porterville: 16% Madera: 11% Merced: 11% Reedley: 11%

After Thursday, temperatures are expected to remain steady through the next week, due to a more zonal flow in the 500mb pattern. The long range ensemble models show this will continue through early next week as well.


AVIATION
Thunderstorms may produce isolated IFR conditions between 19Z today and 03Z Monday. Snowfall above 5,000 feet will produce areas of MVFR with local mountain obscuring IFR conditions through 12Z Monday. Otherwise, VFR conditions are expected for the Central California interior for at least the next 24 hours.
