Area Forecast Discussion
National Weather Service Salt Lake City UT
948 PM MST Thu Feb 15 2018

.SYNOPSIS...A cold upper trough will move out of Utah tonight. A
weak trough will clip far northern Utah Friday night. A warmer
westerly flow will be over the area on Saturday. The next cold
upper trough will start to move into Utah on Sunday and will
remain over the area into Tuesday.


.DISCUSSION...Very light snow showers continued into this evening
near and over the Great Salt Lake and northern mountains but have
finally died off this past hour. Under the clearing skies and the
cold air mass in place temperatures have been falling rapidly in
many areas already this evening with some already nearing or
reaching their forecast lows for overnight. Have lowered temps
across most of northern Utah by a few degrees to account for this
very dry and cold air mass. Alta was 7 degrees and Bear River
RAWS -1 degrees already at 9pm which is not that surprising after
the fresh new snow. Have lowered them several degrees.

Have updated to remove all PoPs for the rest of tonight and
improved sky conditions to clear or mostly clear.


.AVIATION...VFR conditions will prevail through the TAF period at
the SLC terminal. Southeast winds will prevail through the night
then shift to the NW after 20Z Friday.
