...Discussion from SFOFWFMTR...



The exceptional heat wave continues for the remainder of today and

Friday. Saturday will see a roughly 10 degrees drop in daytime highs

with more gradual cooling Sunday into the beginning of next week.

Winds have remained mostly light throughout the event while finer

fuels continue to rapidly cure, especially at higher elevations. The

low mixing height and light winds will continue to limit dispersion

where any ignitions do occur.





...Discussion from SFOFWFEKA...



.A dominant blocking ridging pattern promoting unseasonably warm and

dry conditions persist through Friday.  Winds will continue to be

light to moderate and terrain- driven today, while humidity will

continue to be unseasonably low with  mins from 15 to 35 percent for

the interior. Overnight RH  recoveries values will continue to be

lower than normal with a  midslope thermal belt remains through the

Friday. Wind increases this weekend. Expect breezy to locally gusty

W to NW winds,  especially over the coastal headlands, exposed

ridges and through  the channeled terrain. This uptick in W-NW

breezes will bring a  push of marine moisture on Saturday. This will

moderate the RH's, although areas far east will remain with pockets

of low to  moderate RH values. Cooling expected this weekend with a

return  of rain by mid of next week.
