...Discussion from Monterey...

Mid level moisture continues to stream in from the south while
temperatures continue to moderate. The mid level moisture is
bringing the threat of high based thunderstorms to area. Starting
from south and transiting northward through Tuesday. Probabilities
remain low, but any rouge lightning strike may cause a fire start.
By midweek, an area of low pressure  moving into the Pacific
Northwest will cause more robust onshore  flow. During this time
expect more breezy condition through gaps  in terrain, such as the
Petaluma Gap, Altamont Pass, and the  Salinas Valley. Onshore
conditions will help to keep humidities  higher, though under breezy
conditions.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.

...SLIGHT CHANCE OF THUNDERSTORMS THIS AFTERNOON WITH ISOLATED DRY
LIGHTNING STRIKES POSSIBLE ACROSS INTERIOR SAN LUIS OBISPO AND SANTA
BARBARA COUNTIES AS WELL AS MOUNTAINS OF VENTURA AND EASTERN LOS
ANGELES COUNTIES AND EASTERN ANTELOPE VALLEY...

...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS RETURN ACROSS
INTERIOR AREAS AND SOUTHWEST SANTA BARBARA COUNTY WEDNESDAY INTO
THURSDAY NIGHT DUE TO DRYING TREND WITH CONTINUED WARM TEMPERATURES
AND GUSTY ONSHORE WINDS...

Subtropical moisture from remnants of former tropical cyclone
Alberto remain over the region. Isolated thunderstorms occurred this
morning  across western Santa Barbara county and portions of San
Luis Obispo County.  With daytime heating and better instability,
there is a 10-15 percent chance of thunderstorms this afternoon
across interior portions of Santa Barbara and  San Luis Obispo
counties, and the mountains of Ventura and eastern Los Angeles
counties, as well as the eastern Antelope Valley. The main threats
will be cloud-to-ground lightning strikes including potential fire
starts (isolated dry lightning) and strong wind gusts up to 50 mph
with any stronger thunderstorms. Storms will be slow moving, with
any storms potentially leading to localized flooding concerns,
focused across the mountains. Thunderstorm chances are expected to
reduce to less than 10 percent by tonight and Tuesday.

A large ridge of high pressure over the region will persist into
Tuesday, continuing to bring hot conditions to the interior. High
temperatures between 92 and 103 degrees will be common across the
warmest valleys, lower mountains, and Antelope Valley through
Tuesday. As the high pressure system weakens, there will be a
gradual cooling trend across all areas Wednesday into Friday.  From
Wednesday into Thursday night, there will also be increasing onshore
winds across the interior, with southwest to west winds gusting
25 to 45 mph, strongest in the Antelope Valley. In addition,
sundowner and I-5 Corridor winds will likely return Wednesday into
Thursday night, with potential wind gusts of 25 to 45 mph. The
combination of a drying trend with gusty winds will bring a return
of elevated to brief critical fire weather conditions across the
interior and southwest Santa Barbara county where there will be an
increased risk for grass fire activity. At this time, the most
favored areas for brief critical fire weather conditions would
include the I5 corridor as well as the Antelope Valley and western
foothills.
