...SLIGHT CHANCE OF THUNDERSTORMS MAINLY SOUTH OF POINT CONCEPTION LATE THIS EVENING
INTO TUESDAY MORNING INCLUDING COASTAL AND VALLEY AREAS, WITH MAIN RISKS
BEING ISOLATED DRY LIGHTNING STRIKES POTENTIALLY CAUSING NEW FIRES AND STRONG/ERRATIC
DOWNBURST/OUTFLOW WINDS...
...TRANSITIONING TO THREAT OF WETTER THUNDERSTORMS TUESDAY AFTERNOON THROUGH FRIDAY,
MAINLY FOCUSED ACROSS THE LA/VENTURA MOUNTAINS AND ANTELOPE VALLEY, WITH MAIN RISK
BEING FLASH FLOODING--CONTINUED RISK OF LARGE PLUME DOMINATED FIRES ACROSS DRIER
INTERIOR AREAS THROUGH WEDNESDAY...
..FLOOD WATCH IN EFFECT 11 AM TUESDAY UNTIL 11 PM WEDNESDAY FOR THE SAN GABRIEL
MOUNTAINS, ANTELOPE VALLEY, AND ADJACENT FOOTHILLS INCLUDING BRIDGE FIRE BURN SCAR
FOR POTENTIAL FLASH FLOODING AND DEBRIS FLOWS...
.DISCUSSION...
Hot and dry conditions persisted today away from the immediate coast today,
with high temperatures of 95 to 106 degrees across the valleys, lower
mountains, and deserts. Similar hot temperatures may persist into Tuesday, with
warmer temperatures potentially occurring near the coast due to weakening onshore
flow.
The hotter temperatures combined with increased instability has brought deeper
mixing heights which are peaking between 12,000 and 17,000 feet this afternoon.
As a result, there is an elevated risk for large plume dominated fires across
the interior. Humidities between 10 and 20 percent are common today over the
warmest valleys, lower mountains, and deserts today. then potential humidity
increase by Tuesday or Wednesday due to the influx of monsoonal moistures.
Increasing mid level moisture and instability associated with an upper level
disturbance will bring a slight chance of showers and thunderstorms tonight
into Tuesday morning, mainly south of Point Conception, including coastal
and valley areas. Due to the expected limited rainfall during this time,
the main risks with any thunderstorm activity tonight into Tuesday morning
will likely be isolated dry lightning strikes and strong/erratic
downburst/outflow winds gusting to 50 mph. These isolated dry lightning
strikes will bring an increased risk of lightning induced fires across the
region, especially considering the critically dry fuels. If the dry lightning
coverage were to increase, a short fuse Red Flag Warning may need to be considered.
From Tuesday afternoon through Friday, there will be higher chances of
monsoonal shower and thunderstorm activity across the mountains and deserts
(especially LA/Ventura counties), with a smaller chance for coasts and valleys.
With wetter storms expected, the main risks during this time frame will be the
potential for brief heavy rainfall and flooding threats in the mountains and deserts,
along with a continued threat of strong downburst/outflow winds. The highest threat
for flash flooding and debris flows will be in the San Gabriel mountains and
Antelope Valley where a flood watch is in effect. The potential for
strongest outflow winds, locally damaging up to 60 mph will be Tuesday afternoon
and evening across LA county, especially Antelope Valley, San Gabriel mountains,
and San Gabriel Valley.
