UPDATE

Air Quality Section Updated.



KEY MESSAGES

1. A Wind Advisory has been issued for the Mojave Desert Slopes valid 6 PM this evening through 3 AM Sunday morning.

2. High temperatures today are expected to be around 3 to 6 degrees below seasonal averages.

3. Dry and warming conditions are expected next week, with highs around 8 to 12 degrees above normal by Friday.

DISCUSSION
The area is currently on the lee side of the upper-level trough that went through the past few days, with a zonal pattern set to take over through early next week. The Mojave Desert Slopes are still expected to experience moderately strong winds through early tomorrow morning, therefore a Wind Advisory has been issued for that area from 6 PM this evening through 3 AM tomorrow morning.

As the zonal flow takes over the pattern over California, we will see high temperatures increase to a few degrees above seasonal norms. By Thursday, a ridge will begin building over California, leading to a warming tend that will last through the weekend, with highs 8 to 12 degrees above normal. There is also the possibility (10-25%) that locations in the San Joaquin Valley may see highs around 90 degrees.

The long range models are showing indications of a weak disturbance that may come through by next Monday, mostly leading to a brief cooling trend and slightly faster winds, and precipitation is not very likely. There are more indications of another, stronger trough and inklings of precipitation by May 8th, though there is much disagreement between members on timing, amount, or if it will rain at all.


AVIATION
Expect areas of MVFR with local IFR and terrain obscuration in upslope clouds along San Joaquin Valley facing slopes through 00Z Sunday. Otherwise, VFR conditions will prevail throughout Central California for at least the next 24 hours.
