Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0150 AM CST Mon Dec 16 2024



Valid 171200Z - 181200Z



...Synopsis...

Quasi zonal mid-level flow is expected to quickly amplify as ridging

develops over the Western US D2/Tues. In the wake of a cold front

moving across the central US the day prior, surface high pressure

will quickly build over the Great Basin. The high pressure will

allow for moderate offshore winds and elevated to near-critical

fire-weather concerns over portions of southern CA.



...Southern California...

As high pressure intensifies behind the cold front across the Great

Basin and interior West, moderate offshore flow is expected to

develop D2/Tues into D3/Wed. Santa Ana winds of 15-25 mph will

overlap with low RH values of 10-20% across parts of Los Angeles and

Ventura counties for several hours. Elevated to near-critical

fire-weather conditions appear likely amid dry fuels across portions

of southern CA, particularly overnight D2/Tues into D3/Wed. Some

uncertainty remains regarding the strength of the winds and minimum

RH values in the absence of stronger upper-level support. The best

overlap of strong winds and low RH is expected late D2/Tues into

early D3/Wed morning. However, if winds trend stronger and earlier

as some guidance suggests, critical highlights may be needed sooner.
