.DISCUSSION...
We have cooler temperatures today thanks to a shortwave trough
that is in the area but moving east. This trough brings cooler
temperatures this afternoon but also a 10 to 20 percent chance
of thunderstorms to the Sierra Nevada today. This thunderstorm
potential increases the risk of possible fires.

We have a small ridge building in on Sunday that will increase
temperatures before another shortwave trough moves through on
Monday. This second shortwave will cool afternoon highs, improve
minimum humidities, but also will bring stronger winds to the
area. However, there is a 10 to 20 percent chance of 45 mph wind
gusts in the slopes so a Wind Advisory has not been issued but
could become an option tomorrow. The increase in winds could
also bring

Tuesday starts a warming trend to the area for the remainder of
the week with even a 40 to 50 percent chance of triple digits in
the Valley on Friday. Saturday has a 60 to 70 percent chance of
triple digits. However, afternoon wind gusts will also increase
after Wednesday in the Valley to be around 10 to 15 mph by
Saturday afternoon. The afternoon low humidity is forecast to be
around 15 to 20 percent for much of the week. The combination of
low humidity, increasing temperatures and wind gusts increase
the risk of fire over the week.
