Area Forecast Discussion
National Weather Service Salt Lake City UT
824 PM MST Sun Jan 15 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...A light northerly flow is over the eastern Great
Basin this evening between a sharp ridge off the west coast and
the departing trof moving into the plains. Considerable stratus
covers much of the western and central valleys while the last of
the deformation cloud cover behind the upper trof covers the
eastern CWA. A few light echoes are noted on radar over the Green
River area but cameras before sunset showed this was mainly aloft.

Expect the stratus to remain in place across the west with fog
forming in the colder valleys where it remains clear, such as
Cache and Heber. The stratus should hold temps up again overnight
while it will get quite cold outside of these areas.

The thicker clouds over the east should thin out overnight with
fog potentially forming in some of the eastern basins. Gusty
northeast winds thru the gaps across swrn UT will persist and
increase a bit overnight into Mon morning, altho speeds should
remain sub advisory.

The upstream ridge shifts over UT by Tue eve with inversions
lowering and an increasing chance of western valley fog as this
occurs. The next trof still looks to arrive Thu morning.

Updated earlier to adjust cloud cover and raise min temp forecasts
for tonight in areas with stratus. Also removed pretty much all
pops from the forecast for tonight. No additional updates planned.


.AVIATION...MVFR cigs are expected to prevail at the SLC terminal
through midday Monday. VFR vsbys should continue overnight then
lower into the MVFR range after about 12-13z with brief occasional
MVFR vsbys possible before that. Winds will remain light northerly
through the TAF period.
