.Synopsis...
Valley showers and isolated thunderstorms tomorrow. Light snow
accumulations at pass level. A little breezy behind this system on
Thursday, then dry and warming weather.

&&

.Discussion...
Trough of low pressure will be deepening over the region. Not much
in the way of showers is expected until the afternoon hours with
most showers occurring over the mountains at least at first.
Instability is pretty good so some thunderstorms could develop
during the afternoon and evening hours and that could bring some
activity to the valley. Snow levels look high near pass levels
during the afternoon and precipitation amounts look light so there
may not be much of an impact if travel over the passes.

The low will move into Nevada Wednesday night into Thursday. The
activity will die down with some lingering showers possible near
the crest on Thursday. Breezy northerly winds will develop early
Thursday morning and continue into the early evening hours.
Temperatures will be noticeably warmer on Thursday.

High pressure will strengthen over the area on Friday with
continued warming of temperatures for the region.

.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)

High pressure will remain in control for the weekend into early next week.

temperatures. A period of breezy northerly flow is likely over the
weekend as well. High temperatures will near the 90 degree mark in
the Valley by Sunday with widespread 90s (10 to 15 degrees above
normal) possible by Monday.
