SYNOPSIS

13/341 AM.

Temperatures will largely be below normal today, with low clouds widespread during the morning. Chances are high for widespread sunshine by the afternoon. Gusty winds are expected times across the mountains and deserts. Slight warming is expected Thursday and Friday, and above normal temperatures are possible early next week.

LONG TERM (SUN-WED)

13/150 PM.

For the extended, the excitement levels look to remain on the low side. Models indicate the inside slider will move across the Great Basin on Sunday with some form of upper level trough remaining over the area through early next week.

Forecast-wise, main "concern" will be the winds. With the inside slider, gusty northwesterly winds will continue across the area on Sunday with a decent chance of advisory-level winds across the Interstate 5 Corridor and the Santa Ynez Range. For Monday through Wednesday, no significant wind issues are expected as moderate onshore pressure gradients will prevail with the typical gusty southwesterly winds across interior sections.

As for temperatures, there will be some area-wide cooling on Sunday. However for Monday through Wednesday, there will be a gradual warming trend across the area. By Wednesday, afternoon temperatures are expected to generally be in the mid 70s to mid 80s.

Finally with respect to cloud cover, there will continue to be night and morning low clouds and fog west of mountains each day. Otherwise, mostly clear and dry conditions can be expected.
