.DISCUSSION...

A troughing pattern over much of the western United States is 

maintaining from the weekend, resulting in clear, dry 

conditions for central California with relatively cool 

temperatures near season averages. This pattern is expected to

continue for much of the work week, but gradually weakening as

the holiday weekend approaches. As such, a slight warming trend

is expected later this week, with a 60 to 70 percent probability

for maximum temperatures to exceed 95 degrees on Saturday in the

San Joaquin Valley; until then, there is less than a 20 percent

probability for these highs. However, with the prevailing flow

entering the region from the northwest, drier air is anticipated

to continue, with daily minRH values across the valley areas at

20 percent or less and desert values between 10 and 15 percent;

minRHs at the higher Sierra elevations will also be around 15 to

20 percent with greater RHs in the 30s for the foothills. 



Before getting into the rest of the week, a shortwave low

pressure system is currently breaking off from the main trough 

and will track southward through central California today. The 

increased dynamics from the system and relatively stronger 

moisture influence will bring a slight chance for thunderstorms 

across the crest of the Sierra Nevada this afternoon. Any storm

that may develop can contain cloud-to-ground lightning, gusty

and erratic winds, small hail, and intense rainfall rates.
