Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0203 AM CST Thu Jan 09 2025



Valid 101200Z - 111200Z



...Synopsis...

The upper-level trough in the Northwest will shift south and east on

Friday. This feature is expected to lose amplitude as an upstream

trough moves into the Northwest. As a result, surface high pressure

in the Great Basin/Southwest should lose intensity rather quickly

after the early morning hours.



...Southern California...

The offshore pressure gradient will have been in the process of

gradually weakening for several hours prior to Friday morning. The

weakening trend will continue, especially during the afternoon.

Upper-level wind support will also quickly dissipate after the early

morning as the trough pushes farther east and upper-level ridging

increases in the region. RH will likely remain low through the day.

5-20% RH will be fairly widespread by the afternoon. Winds will

generally reach 15-25 mph. Some locally higher speeds are possible

within the terrain. Given the overall large-scale trends and

high-resolution ensemble guidance, critical fire weather conditions

are expected to occur locally and primarily tied to terrain

features.
