...Discussion from SFOFWFMTR...



Warm and dry conditions through Friday. Gusty northwest winds

develop late Friday to Sunday, with gusts to 45-50 mph across the

ridgetops, along the coasts, and through gaps and passes. Winds will

veer to the north late Sunday and Monday, leading to some offshore

flow in the North Bay. This will reinforce a warming and drying

trend early next week, and result in lower relative humidities

across the interior, increasing fire weather concerns.

RH recoveries will remain high. A warm front will increase cloud

cover today and will bring chances for light  drizzle tonight.

Temperatures will rise back up to near or above  normal on Thursday.

Breezy northwest winds are expected each  afternoon, with gusts from

20 to 30 mph along the coast and  exposed ridges. Potential for very

light rain or light drizzle  returns late Friday night into Saturday

for the northern portion  of the forecast area, especially in Del

Norte. Chances for a  wetting rain have dropped to 40% or less for

mainly Del Norte.  Northwest winds are expected to strengthen this

weekend,  particularly Sunday. Warmer weather will return next week,

with  more chances for weak, clipping weather systems bringing a

shower or periods of drizzle, but likely not a wetting rain.
