.DISCUSSION...

Winds will start off light and variable, much like previous days,
becoming west-southwesterly around 1200 Wednesday. Gusts to 15 to 20
mph will continue from the west-southwest through around 1900 to
2000 Wednesday evening, and winds return to light
downslope/downvalley flows overnight. The same pattern will persist
for the next several days, into the weekend. Winds look to be
strongest Friday afternoon with gusts 20 to 25 mph possible.

Precipitation chances remain generally minimal, with best chances of
the week being Wednesday afternoon (10% chance). Afternoon minimum
RHs are generally expected to be in the 20 to 25% range and
temperatures will be slightly warmer on Wednesday as well. The
slight warming and drying trend looks to continue through the end of
the week, with Friday being the warmest and driest day of the week.
