No changes were made to the existing Elevated wind/RH area over far
southern California on Day 2/Saturday. The previous forecast remains
on track with RH minimums falling below 15-20% amid easterly winds
of 10-15 mph across the drawn area tomorrow afternoon. The San Diego
foothills could see wind gusts that exceed 40 mph during peak
heating.

...Synopsis...
At least Elevated fire-weather conditions are forecast for portions
of Southern California on Saturday as an upper-level ridge
contributes to dry and breezy easterly off-shore flow. Relative
humidity minimums of 15-20% and winds of 10-15 MPH (potentially
gusting higher in the vicinity of the San Diego foothills) should
overlap with modestly dry fuels during the afternoon.

Day 3-8 Fire Weather Outlook

Valid 041200Z - 101200Z
An upper-level high centered over southern/eastern NV will continue
on Day 3/Sunday before breaking down early next week.
Simultaneously, as this break down occurs, westerly surface winds
will become gusty, especially over the lee slopes adjacent to
portions of the northern High Plains - particularly on Day 4/Monday
and Day 5/Tuesday. However, while dead fuel moistures will be drier
as a result of this event, the combination of antecedent fuel
conditions and wind/RH is currently expected to remain below
critical thresholds. After being suppressed by the passing trough
over the northern tier of the CONUS, the ridge will build back
farther east into the Intermountain West mid to late next week as
the pattern remains unsettled.
The upper-level high will contribute to easterly flow over southern
coastal CA, supporting a stronger than average offshore flow regime.
Given the warm and dry conditions preceding and following this
event, fuels will remain receptive. The tightening pressure gradient
will support breezy (10-20 mph) and gusty (30+ mph) offshore flow
amid minimum RHs near 15-20% and well above normal heat over much of
the highlighted area. Atypically, the strongest offshore winds are
anticipated to occur during the daytime hours on Day 3/Sunday. Thus,
40% probabilities of critical wind/RH remain in the forecast.
