Day 2 Fire Weather Outlook

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.
