Area Forecast Discussion
National Weather Service Salt Lake City UT
1000 AM MST Fri Jan 13 2017

.SYNOPSIS...An upper level low will continue to move south along
the coast today moving eastward along the Mexico and Arizona
border Saturday. In the wake of this low, a drying trend will
follow into the weekend. A more active pattern will redevelop by
the middle of the week.

&&

.DISCUSSION...The end of a very active storm cycle is underway
this morning. A slow moving upper level low is currently located
along the California Coast. As upper level ridging amplifies over
the eastern Pacific, this upper level low will transition to a
more easterly motion and cross northern Mexico near the US border
Saturday.

Occasional light snow/flurries has been reported across portions
of western Utah. Meanwhile, across southern and eastern Utah,
upslope combined with warm air advection will continue to produce
periods of light snow through the afternoon and into the evening,
especially above about 5500 to 6000 feet.

Cancelled the winter headlines for west central Utah and the
Sanpete and Sevier Valleys as cams/radar/satellite indicate mainly
low stratus has developed in these areas and the threat of
accumulating snow has diminished.

The remainder of the headlines for eastern and southern Utah
expire at 18Z. While light snow will continues at times, after
coordinating with partners, expect impact to be minimal. Barring
new information in the next hour, anticipate letting these
headlines expire at 18Z.

A lull in the weather is expected as ridging builds into the West.
The next appreciable threat for widespread precipitation looks to
be mid-week next week.

Updated pops, sky and other grids to reflect current trends.
Otherwise, forecast is on track and no additional updates are
anticipated at this time.

&&

.AVIATION...VFR conditions are expected to prevail at the SLC
terminal through today and into about 04-06Z this evening when
visibilities will lower in BR. Ceilings are expected to be near
BKN070 or higher but temporary ceilings near BKN060 are possible
through 19Z. Winds will be calm or northerly through the TAF

06Z tonight.
