...LONG DURATION HEATWAVE WITH WIDESPREAD ELEVATED FIRE WEATHER
CONDITIONS INCLUDING POTENTIAL FOR LARGE PLUME DOMINATED FIRES AWAY FROM
THE COAST FROM WEDNESDAY THROUGH SUNDAY...
...FIRE WEATHER WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH
SATURDAY EVENING FOR AN UNSEASONABLY HOT AND UNSTABLE AIR MASS
CAPABLE OF PRODUCING EXPLOSIVE FIRE BEHAVIOR FROM VERTICAL PLUME
GROWTH...LOW RELATIVE HUMIDITY...AND LOCALLY BREEZY WINDS FOR
PORTIONS OF THE MOUNTAINS AND FOOTHILLS OF LOS ANGELES AND VENTURA
COUNTIES...
.DISCUSSION...
There will be gradual warming and drying across the interior on Monday
and Tuesday as upper level high pressure begins to expand westward. There
will be gusty Sundowner winds the next few evenings, mainly focused from Gaviota
to San Marcos Pass. Wind gusts of 35 to 50 mph will be common each evening.
While humidity levels will be elevated this evening, but could lower into
the 20 to 40 percent range on Monday evening and Tuesday evening, thereby
increasing the fire weather concerns for southwest Santa Barbara county.
A long duration heat wave is becoming more likely from Wednesday through
Sunday. With onshore flow expected to be weaker with this event, heat
impacts could potentially spread to inland portions of the coastal plain.
The combination of hot temperatures, low humidities (including poor overnight
recoveries in the mountains and foothills), instability, locally breezy conditions,
and critically dry fuels away from the coast, will likely bring widespread elevated
fire weather conditions across the valleys, mountains. During the peak of the heatwave,
which will likely be Thursday through Saturday, temperatures could soar to between
98 and 110 degrees for the valleys, lower mountains, and deserts, with minimum
humidities generally ranging between 8 and 20 percent, and mixing heights potentially
rising to between 12,000 and 17,000 feet across the interior. While widespread strong
winds are not anticipated with this upcoming heat wave, the hot temperatures,
low humidities, increased instability, locally breezy conditions (mainly across
mountains, foothills, and canyons), and critically dry fuels will bring the
threat of large plume dominated fires (especially in the mountains and
foothills), capable of rapid growth and extreme fire behavior. The highest risk
areas will be the interior mountains and foothills of Los Angeles and Ventura
counties, as well as Santa Clarita Valley where a Fire Weather Watch has
been issued. The Fire Weather Watch area covers portions of the mountains and
foothills of Los Angeles and Ventura Counties, which have been a climatologically
notorious area for large plume-dominated fires in similar weather patterns to
what is coming later this week. Moreover, the western edge of a southwest-states
monsoonal moisture influx will overlie Los Angeles and Ventura Counties,
which will contribute to the development of atmospheric buoyancy by Friday and
Saturday without significantly moistening the airmass -- i.e., displaced away
from the core of the moisture source. While lightning-induced fire ignitions
are a distinctive possibility on the peripheries of rain cores, the increase in
buoyancy will further aid in vertical plume growth accompanied by
potential pyrocumulus development and related explosive fire behavior.
