.SHORT TERM...Today through Monday...A dry northwest flow aloft
will be accompanied by clear skies through Monday. Temperatures
will be 5 to 10 degrees cooler (near normal) today as a result of
dry cold front which moved through last evening. Winds will
increase through the day, becoming breezy to locally windy by the
afternoon. The winds will diminish this evening and remain light
through Monday. Temperatures will be near normal on Monday.

.LONG TERM...Monday night through Sunday...The pattern shifts
Monday night as an upper ridge moves across the Intermountain
West. A weak trough passage on Wednesday night will bring residual
moisture from the weakening tropical storm in the Pacific for a
slight chance of thunderstorms in the mountains. Overall, this
trough will bring increased cloud cover to the forecast area into
early Thursday. The upper ridge amplifies on Thursday, allowing
for dry southwest flow that will increase temperatures roughly
7-10 degrees above normal into the weekend.
