Area Forecast Discussion
National Weather Service Salt Lake City UT
1000 PM MST Tue Jan 31 2017

.SYNOPSIS...A ridge of high pressure will remain in place across
the region through Friday. However a series of weak weather
systems will begin to cross the northern portions of the area
tonight through the weekend gradually weakening the ridge.

&&

.DISCUSSION...A low amplitude mid level ridge is centered along
the Sierra crest this evening, while a mid level trough is noted
sagging south into the Pacific Northwest. This is resulting in a
belt of westerlies across the northern Great Basin region, which
is accompanied by an extensive plume of mid and high level
moisture. Meanwhile, strong but shallow valley inversions remain
in place across most northern and central Utah basins. With
extensive overnight cloud cover, overnight min temps should remain
quite a bit warmer than what has been recently observed. Updated
earlier to expand cloud cover into central Utah per satellite
observations. Otherwise going forecast looks in good shape.

&&

.AVIATION...MVFR visibility is expected to prevail at KSLC through
the night with CIGS remaining above 7 kft. There is a 20 percent
chance IFR CIGS develop during the overnight hours. Winds are
expected to remain predominantly northerly, but may become light
and variable at times.

&&

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