.KEY MESSAGES...

- Lingering light snow with minimal accumulations will continue
  into this afternoon mainly across southern and central Utah. In
  the wake of this storm, some of the coldest temperatures of the
  season can be expected Sunday morning.

- Gap winds will develop in favored areas of southwest Utah this
  afternoon and evening.

.DISCUSSION...An upper trough continues to carve south into Utah
this morning, pushing the existing cold front into southern utah.
Radar imagery shows a few associated showers currently in place
across central and southern Utah. These showers are expected to
increase a bit for this morning ahead of the trough axis. Minor
additional accumulations are expected (generally 2 inches or less
in the mountains and 0.5 inches or less in the valleys) before
precipitation winds down this afternoon.

Behind the cold front, northerly flow and cold advection will
bring gap winds to Washington County. Wind gusts of around 40-50
mph will be possible this afternoon and evening for a few hours.
Despite hitting on the low end of advisory criteria, due to
localized nature and limited impacts, have opted not to go with
any wind highlights at this time.

Temperatures today will run a bit below climatological normal.
Northern and most central Utah valleys will fail to reach 40F,
while far southern through east-central Utah valleys will trend
closer to 45-50F. As the storm system exits the area tonight,
clearing skies will lead to cold overnight mins of around 3-8
degrees below normal. With some northerly winds still in place,
apparent temperatures (wind chills) will be in the mid teens along
the Wasatch Front, and down to single digits in many other
valleys.

Utah will remain under a north to northwesterly flow aloft through
Tuesday before a shortwave ridge shifts over the area for
Wednesday. A series of grazing shortwave disturbances should keep
inversions from becoming very strong until the ridge arrives. The
first of these shortwave disturbances, arriving on Sunday, could
bring some light snow to the Uintas. The second of these, arriving
on Tuesday, currently appears to be a bit drier. Once the
shortwave ridge arrives on Wednesday, the question becomes how
long will it maintain its position over the area. The
deterministic GFS has had some recent solutions which would bring
a trough into the area on Thursday accompanied by some
precipitation. The 00Z deterministic EC has now come on board
with a similar idea. Something to get excited about? Not really,
as the trough in question will have the tendency to split, which
results in lower confidence in any given solution. The latest NBM
maintains 0 QPF areawide even at the 75th percentile.

.AVIATION...KSLC...Northwest winds fill into the area following the
passage of a frontal boundary and will persist through the period.
Occasional gusts nearing 20kts in the afternoon are possible and
will diminish by sunset. VFR conditions will prevail throughout the
period.

.REST OF UTAH AND SOUTHWEST WYOMING...A frontal boundary will
continue sweeping through the forecast area bringing northwest winds
through the remainder of the period to all sites. Additionally,
clouds will be scoured out as drier air fills in, though some valley
sites such as KLGU and KHCR may hang on to low stratus into the
morning before mixing out in the late morning. Outside of occasional
MVFR CIGs at those two sites, VFR conditions will prevail through
the period.

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
