this evening. Widespread triple digit heat is expected in the San

.DISCUSSION...
An upper-level area of high pressure will be centered near the 
Four Corners region of the United States today. Southeast to south
flow aloft along the western periphery of this anticyclone aloft
will advect monsoonal moisture northward into Central California
today. A few strong thunderstorms are conceivable in the Kern
County desert and Sierra Nevada crest south of Fresno County this
afternoon and this evening. The aforementioned upper-level area 
of high pressure will move southward into the Desert Southwest 
Tuesday and Wednesday. As a result, the flow aloft will veer to 
more of a dry, southwesterly direction. Widespread triple digit
heat is anticipated in the San Joaquin Valley each afternoon today
through Wednesday. Here are triple digit heat probabilities for 
select locations in the San Joaquin Valley on Wednesday, July
26th, 2023:

Lemoore - 91%
Fresno - 86% 
Bakersfield - 86%
Visalia - 81%
Hanford - 81%
Porterville - 81%
Delano - 81%
Reedley - 56%
Merced - 51%
Madera - 51%

A ridge of high pressure will extend westward across Southern 
California Thursday. An Eastern Pacific trough of low pressure 
will approach the west coast of the United States Friday. This 
trough of low pressure will make landfall over Northern California
Saturday. Cyclonic flow aloft will persist over the Golden State
Sunday. Maximum temperatures Thursday through Sunday will be near
their typical values for the latter half of July.

.AVIATION...
IFR or lower conditions are possible in the Kern County desert and
Sierra Nevada crest south of Fresno County this afternoon and this
