...Discussion from SFOFWFMTR...



Warming and drying trend continues through Saturday with good

overnight relative humidity recovery outside of the  highest

terrain. Away from the immediate coast expect little to  no marine

layer influence with above normal temperatures and poor  daytime

relative humidity. Unsettled weather returns Sunday with  cool

conditions and moderate winds. Light rainfall is expected  Monday

with wetting rains likely for the North Bay. There's a low

probability for thunderstorms Monday into Tuesday which would  pose

the risks of lightning, small hail, and locally heavy  rainfall and

gusty winds.





...Discussion from SFOFWFEKA...



Warm temperatures expected through Saturday with Friday expected to

be the warmest and driest day. Winds will mianly be light and

terrain driven with some afternoon westerly winds of 10 to 15. Late

Sunday into Monday there is a 30 to 75 percent chance of a wetting

rain with the highest probabilities in the north. Much cooler

temperatures are expected as well.
