Area Forecast Discussion
National Weather Service Salt Lake City UT
920 PM MST Sun Jan 14 2018

.SYNOPSIS...Strong high pressure centered to our west will start
to weaken on Monday. A weak system will cross the area late
Tuesday through early Wednesday. A colder and wetter weather
pattern will develop starting Friday.

&&

.DISCUSSION...The large-scale pattern this evening per water vapor
imagery and model analyses shows Utah remaining under a northwesterly
flow aloft downstream of a high-amplitude ridge which continues to
slowly shift eastward across the Great Basin. High clouds have
started to increase from the west, otherwise expect another quiet
night under dry and stable conditions. Max temperatures in the
valleys outside of Dixie made it into the 40s and 50s once again
today, although some northern and western Utah valleys were a bit
cooler than yesterday. Inversions have yet to build in strongly, as
the 00z SLC sounding shows the base of the inversion around 2500 ft
off the surface.

No updates this evening.

&&

.AVIATION...Operational weather concerns will remain minimal at the
KSLC terminal through the valid TAF period. Light southeasterly
winds are expected to prevail through the night, although periods of
light and variable winds will remain possible through 06-07z. VFR
conditions will be maintained with increasing coverage of thin high
clouds.

&&

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