Area Forecast Discussion
National Weather Service Salt Lake City UT
924 AM MST Mon Jan 16 2017

.SYNOPSIS...High pressure aloft will settle over the Great Basin
for the first half of the week. A return to an active weather
pattern will occur late in the week.


.DISCUSSION...High pressure continues to build over the Great
Basin this morning, contributing to more and more stable
conditions across Utah and southwest Wyoming. Valley inversions
that are already in place will only strengthen, and much of the
stratus that has developed over the northern and western valleys
will likely remain in place. That said, a few pockets here and
there have broken out into partly cloudy skies, but with most
model guidance performing poorly or too coarse to make out the low
level details, persistence should generally remain the best
forecast across the area in the short term.

Once the ridge fully sets up over the region, little change is
expected through Tuesday and Wednesday. Air quality will generally
deteriorate in the valleys, while temperatures slowly but surely
warm in the mountains. It currently looks like the next storm will
push through the area on Thursday, though questions remain about
how much of this energy digs southward.

Updated the forecast earlier today to tweak some of the cloud
cover, including in a couple places that have broken out of the
stratus this morning. Will continue to watch primarily cloud cover
and maybe temperatures for any further updates through today.


.AVIATION...MVFR cigs with occasional MVFR vsbys will prevail at
the SLC terminal through the TAF period. There is a 30 percent
chance that brief VFR conditions will develop today but overall
MVFR conditions will dominate. Winds will be northerly through the
TAF period.
