.DISCUSSION...

As an upper level trough continues its exit from California and
into the Great Basin area, north winds continue today and Monday
through the western portions of the Sacramento Valley & Delta.
This also brings fire weather conditions Sunday into Monday.
Strongest winds and most fire weather conditions peaked this
morning, but gusty conditions will linger through the afternoon
and overnight into Monday. Additionally on Monday, a lobe of
energy phasing out of the exiting trough will bring isolated
mountain thunderstorm chances (10-15%) south of I-80 in the
afternoon and evening.

Tuesday and beyond, another cooling trend is expected which will
result in below normal temperatures across interior NorCal and
periods of breezy onshore flow in the forecast. By the end of the
week, troughing will phase out of the area and temperatures will
return to more normal for the time of year. The holiday weekend
currently looks like it will see Valley highs in the 90s, with
decent overnight cooling (especially near the Delta) which will
provide relief from the warmer daytime temps.
