...RISK OF MONSOONAL THUNDERSTORMS THROUGH TUESDAY, MAINLY OVER THE
MOUNTAINS AND DESERTS, WITH MAIN THREATS BEING ISOLATED DRY LIGHTNING
STRIKES AND STRONG OUTFLOW WINDS...
.DISCUSSION...
High pressure over the four corners states expanding westward over the
region is resulting in a long duration and dangerous heatwave through
Sunday. Similar hot temperatures are occurring today as compared to
yesterday, ranging from 98 to 110 degrees across the interior.
With continued weak onshore flow, the hot temperatures will spread
into portions of the coast with associated heat impacts. A few
degrees of cooling will likely occur across the region over the
weekend, but significant heat impacts will likely continue.
Minimum humidities away from the immediate coast are generally
expected to range between 8 and 20 percent through the weekend,
with a slight increase in humidity levels across the higher
mountain elevations over the weekend due to the influx of some
mid level monsoon moisture. The hot temperatures combined with
increasing instability in the atmosphere will result in deeper
mixing heights of 12,000 to 18,000 feet across the interior through
the weekend,
While widespread strong winds are not anticipated with this
heat wave, the combination of hot temperatures, low humidities
(including poor overnight recoveries in the mountains and foothills),
instability, locally windy conditions, isolated dry lightning strikes
and critically dry fuels away from the coast will likely bring
widespread elevated fire weather conditions away from the immediate
coast. Additionally, the aforementioned parameters will bring the
threat of large plume dominated fires (especially in the mountains
and foothills), capable of rapid fire growth and extreme 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 are
in effect. The Red Flag Warning areas cover areas that have been
climatologically notorious areas for large plume-dominated fires in
similar weather patterns to what we are currently experiencing.
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 today through
Sunday without significantly moistening the airmass -- i.e., displaced
away from the core of the moisture source. While isolated lightning-induced
fire ignitions are possible through this weekend, the increase in
buoyancy will further aid in large vertical plume growth accompanied
by potential pyrocumulus development and related extreme fire behavior.
At this time, it appears that most of the convective activity will
be high based through the weekend, with limited rainfall across our
region. The higher threats with any thunderstorm activity will be
isolated dry lightning strikes as well as strong and erratic downburst/
outflow winds. The best chance of convection (20-40 percent) through this
weekend will be focused across the mountains of LA/Ventura counties
and Antelope Valley, with around a 5-15 percent chance for all other
areas (including coasts/valleys) on Saturday and Sunday.
