.DISCUSSION...
We have a weak ridge of high pressure over the Pacific Coast
keeping us warm with a minor heat risk. Wednesday brings a 35 to 60
percent chance of triple digits for most Valley locations with a
60 to 95 percent chance of high temperatures of at least 105 degrees
for the Mojave Desert and Slopes. Probabilities decrease on Thursday
with a 30 to 90 percent chance of highs of at least 105 in Eastern
Kern County and a 45 to 80 percent chance of triple digits in the
San Joaquin Valley from Fresno on south.

Temperatures decrease Friday into the weekend as a strong trough slides
in. There is an at least 80 percent chance of high temperatures below 85
degrees on Saturday for the Valley. In the Mojave Slopes and Desert, wind
speeds will pick up with this trough. Mojave has a 50 to 75 percent chance
of max gusts of at least 60 mph. A wind product is not out of the question
this far out for the Mojave Slopes and Desert.
