KEY MESSAGES
1. High temperatures Tuesday afternoon will be around ten degrees above normal for this time of year.
2. On Tuesday afternoon there is as much as 46 to 56 percent probabilities for high temperatures in Fresno, Hanford and Lemoore reaching 80 degrees for the first time in the calendar year.
3. A downward temperature trend is expected beginning Wednesday.
4. The next storm system will impact Central California by this weekend, resulting in periods of precipitation.
DISCUSSION
Central California remains in an easterly flow between the low pressure area spinning cyclonically near the CA/AZ border and the high pressure area to our north. In this pattern, we are experiencing generally mild conditions, with afternoon highs running several degrees above normal. The cyclonic flow around the low pressure center will continue to create around 10-15 percent probabilities for some convective activity this afternoon and evening over the Kern County mountain and desert areas and expanding farther north to include the Sierra through Fresno County on Tuesday.
Here are the latest probabilities of maximum temperatures of 80 degrees or higher for select locations in the San Joaquin Valley on Tuesday, March 19th, 2024:
Fresno - 56% Lemoore - 46% Hanford - 46% Delano - 36% Visalia - 31% Madera - 26% Bakersfield - 21% Merced - 11% Reedley - 11% Porterville - 16%
By Wednesday, a developing Northeast Pacific low pressure complex will begin to break up the current blocking pattern and the persistent low will lift out while the upper ridge migrates eastward from California. We will see a slight downward trend in temperatures Wednesday through Thursday, with little change on Friday ahead of the approaching low pressure system. The arrival of the storm system will mark the beginning of a more progressive and unsettled pattern for us. High temperatures will drop to around normal by Saturday and as much as 4 to 8 degrees below normal for the start of next week.
The system will bring mainly light to moderate rainfall amounts through the weekend into the start of next week. San Joaquin Valley locations will see mostly one tenth of an inch or less along the west side and south end, and one quarter to one third of an inch as you go further east toward the foothills where a total of as much as one to one and a half inches is expected.
Snow levels will start out around 6500 to 7000 feet Late Friday as the system moves in and lower as low as 4500 to 5000 feet by Sunday. Total snowfall amounts are currently forecast to be as much as 1 to 2 feet in the higher elevations around the Yosemite vicinity, down to around 6 to 12 inches farther south into Tulare County. Weather Prediction Center indicates a significant area of the Sierra from Fresno County north with a 40 to 50 percent likelihood of moderate impacts from heavy snow Saturday.
AVIATION
Besides a few spotty showers over the Sierra Nevada and Kern County mountains and desert at times this evening and again Tuesday afternoon, VFR conditions will prevail across Central California for the next 24 hours.
AIR QUALITY ISSUES
None.
