SYNOPSIS

After a cold morning Saturday, temperatures trend upwards each day over the weekend through Monday. Fair, dry, and warm weather likely persists through next week.

PREVIOUS DISCUSSION...Issued 251 PM PST Fri Feb 20 2026

Weak high pressure aloft develops for this weekend, and there is also an offshore pressure gradient that develops tonight and lasts through Saturday. That will produce areas of gusty easterly winds through the peninsular mountains locally into inland valleys. That will boost the warming trend west of the mountains. The offshore flow weakens a little on Sunday, but the warming trend continues into Monday. High temperatures will be in the 60s Saturday, 70s Sunday, and a few spots should hit 80 degrees Monday. Skies will have periods of high clouds, but the sun will shine through most of the time. Our upper ridge of high pressure over California will amplify some next week. A plume of moisture tries to approach SoCal next Wednesday, but now nearly all model guidance steers that moisture into northern and central California. Confidence is nearly 100% that SoCal will stay dry through at least Friday. It will be a little cooler Tuesday through Thursday as weak onshore flow returns, but still well above normal. The ridge appears to amplify later next week, which if it does, could produce widespread temperatures in the 80s in the valleys, and lower 90s in the low desert on Friday.
