...Discussion from Monterey...

Fire weather concerns will elevate this upcoming week. An Excessive
Heat Watch remains in effect for most of our area away from the
coastline for Tuesday through Friday. ERCs are quickly shifting into
the 70ish percentiles and higher in areas prone to grass fires. The
high heat and subsequent low RH values, poor overnight RH recovery
and the associated risks of fireworks with the Fourth of July - all
makes for a combustible situation,  please plan accordingly.

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

...SIGNIFICANT INTERIOR HEAT POSSIBLE BEGINNING TUESDAY AND CONTINUING
THROUGH NEXT WEEKEND WITH ELEVATED TO BRIEFLY CRITICAL FIRE WEATHER
CONDITIONS...

A broad upper level trough over the West Coast will gradually weaken
through Monday. This will bring a warming trend to all areas through
Monday with the best warming away from the coast. The marine
inversion will remain quite shallow with night and morning low
clouds and fog mainly confined to the coastal plain. Away from the
coast, relative humidity will drop into the teens and 20s with poor
to moderate overnight recovery. Typical diurnal winds are expected
for most areas with gusty southwesterly winds across interior
sections each afternoon and evening.

Beginning on Tuesday, and continuing into next weekend, high
pressure will build in from the Eastern Pacific. This will bring a
very significant warming trend to all areas through next week. The
heat is expected to peak next Friday and Saturday with afternoon
temperatures in the upper 90s to 118 from the coastal valleys to the
deserts with coastal temperatures topping out in the 80s to lower
90s. Overnight low will remain quite warming, resulting in the
potential for dangerous heat the second half of next week. Relative
humidity will drop into the teens and single digits in the afternoon
hours away from the coast with limited overnight recovery. Typical
diurnal winds are still anticipated with gusty  southwesterly winds
across interior sections in the afternoon and evening. Given the hot
temperatures, low relative humidity, and gusty diurnal winds,
elevated to brief critical fire weather conditions are likely away
from the coast.
