...GUSTY AFTERNOON WINDS THROUGH TUESDAY IN ALL INTERIOR AREAS...
...LOW AFTERNOON RH IN TRINITY, NE MENDOCINO, AND LAKE COUNTIES
THROUGH MONDAY...
.DISCUSSION...Dry weather and near to below normal interior
temperatures continue through mid next week. Breezy westerly winds
are likely in the interior areas each afternoon through at least
Tuesday. A deep marine layer will support higher afternoon RHs in
areas closer to the coast (high 20s to 40s). Areas farther inland
will see afternoon RHs in the single digits to the low 20s. These
low RHs combined with breezy afternoon winds will elevate fire
danger in Trinity, northeast Mendocino, and Lake Counties through
Monday. Afternoon RH rebounds slightly Tuesday. Hot temperatures
return late next week into the weekend.
