...Discussion from Monterey...

Moderate temperature and humidity will prevail through the week,
with some strong onshore wind gusts each afternoon. The marine layer
will deepen as a weak disturbance  moves through mid-week. While
unlikely, there is a small chance  for dry lightning from
Monday-Wednesday across the North Bay. Most of the convective
activity should stay in the higher terrain of  the Cascades and
Sierra Nevada, but a slight chance for  thunderstorms remains in the
North Bay. In the unlikely event  that storms develop in our area,
most rain would evaporate before  reaching the ground, making any
cloud-to-ground lightning stikes  more likely to start a fire.

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

...ELEVATED RISK OF GRASS FIRES ACROSS THE INTERIOR THROUGH AT LEAST
WEDNESDAY DUE TO GUSTY ONSHORE WINDS WITH VERY WARM AND DRY
CONDITIONS...

A shallow marine layer remains in place this morning, with low
clouds and fog mainly confined to the coastal plain. An approaching
upper level trough will bring a deepening marine layer Tuesday into
Wednesday, with low clouds and fog likely spreading into the
valleys. While this increased marine layer influence will bring some
cooling to coasts and valleys, there will be little change in
temperatures across the interior above the marine  layer, with highs
88 to 98 degrees common today through Wednesday. Humidities will
fall to between 8 and 20 percent each day across the interior, with
poor overnight recoveries tonight across the San Gabriels and
interior foothills. Southwest winds of 15 to 25 mph with gusts of
25 to 35 mph will be common across the interior through at least
Wednesday, with isolated gusts as high as 40 mph across the Antelope
Valley foothills.  The gusty onshore winds in combination with the
seasonably warm and dry conditions will result in an elevated risk
of grass fires across the interior through at least Wednesday,
especially in the Antelope Valley and adjacent foothills.
