.SYNOPSIS...High pressure will build across the region today. The
next storm system will bring widespread precipitation later
tonight into Sunday. Warmer weather is in store for the first
part of next week.

&&

.SHORT TERM (Through 00Z Wednesday)...Early morning satellite
imagery and objective analysis shows shortwave ridging building
across the eastern Great Basin. Low level warm advection
downstream from this ridge axis continues to fuel showers across
northern Utah, however as the ridge axis approaches and subsidence
continues to increase this activity should quickly come to an end
by mid morning.

The next shortwave trough currently approaching the Pacific coast
is forecast to move inland today, before ejecting northeast
across the far northern Great Basin and Snake River Plain late
today through tonight. The trialing and weakening baroclinic zone
and associated moisture plume is expected to cross northern Utah
and southwest Wyoming tonight through Sunday morning bringing a
round of valley rain and mountain snow, although total QPF/snow
amounts look to remain on the light side given the fact the upper
forcing and cold air aloft all pass well north of the area.

Mid level ridging in the wake of this feature is expected to
amplify later Sunday into Monday, before the ridge axis shifts
east later Monday into Tuesday. The net result in will be a
warming and drying trend with temperatures climbing above climo
early next week.

.LONG TERM (After 00z Wednesday)...Upper level ridging will be
present through the beginning of the long term portion of the
forecast. A deepening trough is expected to approach the coast
Wednesday afternoon. Several waves are expected to eject ahead of
this trough later Wednesday into Friday. As an upper level ridge
begins to amplify off the Coast Friday afternoon, the back edge of
the trough will gradually pull away from the area Saturday. Another
period of upper level ridging is expected to impact the area into
early next week.

Expect the period from Wednesday afternoon to Friday to be
unsettled, with periods of precipitation. Temperatures may be cool
enough to occasionally drop snow levels to near valley floors mainly
later Thursday into Friday.

&&

.AVIATION...Intermittent showers are expected to continue at the SLC
terminal through early this morning. Ceilings will gradually lift
between 12-15Z to above 7000 feet AGL.
