...Discussion from Monterey...

.Excessive heat continues, but a slight cooling  trend will be in
place for the next few days. This will be coupled with improvements
in humidity recoveries and retention.  Conditions will continue to
gradually improve through Tuesday,  with a slight rebound in heat
and dryness Wednesday and Thursday  before cooling continues into
the weekend.


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

SOUTHWEST TO NORTHWEST WINDS, HOT TEMPERATURES, AND LOW
HUMIDITIES...

...WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS
WITH LARGE PLUME POTENTIAL ACROSS INTERIOR VALLEYS, MOUNTAINS, AND
DESERTS THROUGH MUCH OF THIS WEEK...

Long lasting and extremely hot conditions will continue through much
of this week across the interior. For today, very hot temperatures
and low humidities continued across the interior valleys, mountains,
and deserts with highs between 100 and  115 degrees and minimum
humidities between 5 and 15 percent (hottest and driest in the
Antelope Valley). Onshore flow will continue to strengthen through
the afternoon and evening, causing stronger and more widespread
onshore winds across the interior, with gusts between 25 and 40 mph
common, except isolated gusts to 45 mph in the Antelope Valley
foothills. These strengthening onshore winds combined with the
lingering hot and  dry air mass will make fire weather conditions
more dangerous today and tonight across the interior where
widespread elevated to brief critical fire weather conditions exist.
The longest duration of gusty winds overlapping with low humidities
and hot temperatures will be the Interstate 5 corridor and western
Antelope Valley foothills, where a Red Flag Warning remains in
effect through tonight. In addition, the hot and unstable conditions
will make conditions favorable for large vertical plume growth with
any new or existing fires (Lake Fire), as projected mixing heights
between 10,000 and 18,000 feet will be  common. Conditions remain
favorable for large fire growth and extreme fire behavior across the
interior, especially in the Red Flag Warning area. For the coasts
and coastal valleys, the strengthening onshore flow and marine layer
influence will continue to bring a cooling trend with higher
humidities today.

Very hot conditions will change little over the mountains, interior
valleys, and deserts through most if not all of this week, resulting
in a continuation of elevated to brief critical fire weather
conditions. As the marine layer becomes more shallow Tuesday through
Thursday, there is the potential for a warming and drying trend for
the coasts and valleys. In addition, there is the potential for some
gusty sundowner winds with lower humidities across portions of
southern Santa Barbara county (mainly Gaviota to San Marcos Pass)
during the late afternoon through nighttime hours from Tuesday
through Thursday. This is one of the longest and most extreme heat
waves on record for interior areas. For the foreseeable future,
there will be a higher risk for large fires and plume dominated
fires across the interior. There is a high risk for heat related
illness as well.
