.SHORT TERM...(Today through Thursday)
Issued at 250 AM MDT Wed Apr 25 2018

High pressure will build in today bringing sunny skies and
temperatures several degrees warmer than seen yesterday. A few
afternoon breezes are possible but nothing too excessive. Similar
conditions on Thursday though a weak shortwave will drop down from
Wyoming. As it moves through, a few stray showers are possible
over the northern mountains but with a dry atmosphere in place, do
not expect too much precipitation to reach the ground.
Temperatures will inch up a few more degrees.

.LONG TERM...(Thursday night through Tuesday)
Issued at 250 AM MDT Wed Apr 25 2018

The upper level ridge axis will be passing overhead Thursday
night and Friday with scattered convection developing Friday
afternoon. Convection will be confined to the higher elevations
and looks to be more dry than wet underneath this ridge.

Southwest flow strengthens Saturday with shortwave energy working
northeast out of the Great Basin and into the Four Corners area.
This will bring an increasing chance for showers and thunderstorms
by Saturday afternoon. Confidence is still not high though as the
models continue to offer differing solutions with timing and
strength, likely influenced by a deeper upper low that will be
pushing into the Pacific Northwest. The new GFS model run is
tracking this low across central Idaho and across Montana with
drier westerly flow sweeping over our area for Sunday and Monday.
More energy then fills into the Great Basin Monday night and
Tuesday with unsettled weather returning to the region.

Temperatures will be running on the warm side of normal for much
of this period with slight cooling Monday and Tuesday.
