Area Forecast Discussion
National Weather Service Salt Lake City UT
1020 PM MST Sun Feb 11 2018

.SYNOPSIS...A series of weather disturbances will impact much of
Utah beginning late tonight and continuing through at least
Tuesday. After a short break late Tuesday night through early
Wednesday, another round of precipitation will expand across the
state late Wednesday through Thursday.

&&

.DISCUSSION...A shortwave trough rotating into the Great Basin
will help carve out an upper low across the region during the day
Monday. The associated surface trough and low level baroclinic
zone extends across northwest Utah at this time, and is expected
to move little over the next 24 hours, before the developing low
begins retrograding offshore. A mild airmass remains in place
across the forecast area with large dew points depressions
hovering around 30F along the Wasatch Front. As such despite large
scale ascent associated with the weakening shortwave lifting
through the area later tonight into Monday morning, it will be
challenging to overcome the dry low level airmass and see much
more than a few flurries or sprinkles in the valleys with very
light snow in the higher terrain late tonight into the day Monday,
with a better focus for large scale ascent developing across the
south Monday night. Will make a few tweaks to the near term grids
but in general going forecast seems to have this well in hand.

&&

.AVIATION...South winds and VFR conditions will prevail at KSLC
throughout the overnight hours.

&&

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