LUIS OBISPO COUNTIES...
...LONG DURATION HEATWAVE WITH WIDESPREAD ELEVATED FIRE WEATHER
CONDITIONS INCLUDING POTENTIAL FOR LARGE PLUME DOMINATED FIRES AWAY FROM
THE COAST FROM WEDNESDAY THROUGH SUNDAY...
.DISCUSSION...
There will be gradual warming and drying across the interior today
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, it could lower into
the 20 to 40 percent range on Tuesday evening and Wednesday evening, thereby
increasing the fire weather concerns for southwest Santa Barbara county.
A long duration heat wave is likely from Wednesday through Sunday. With
onshore flow expected to be weaker with this event, heat
impacts will likely spread to inland portions of the coastal plain, where
temperatures between 90 and 100 degrees will be likely. 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 away from the immediate coast. 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 fire growth and explosive fire behavior, including
the potential for pyrocumulus development. The highest risk areas will be the
mountains and foothills of Los Angeles, Ventura, Santa Barbara, and San Luis
Obispo counties, as well as Santa Clarita Valley and Cuyama Valley, where
Red Flag Warnings and Fire Weather Watches are in effect. The
Red Flag Warning and Fire Weather Watch areas cover areas that have been
climatologically notorious areas 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 Friday through Sunday 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 large vertical plume
growth accompanied by potential pyrocumulus development and related explosive
fire behavior.
