Area Forecast Discussion
National Weather Service Salt Lake City UT
1006 PM MDT Sun Sep 15 2019

.SYNOPSIS...
Warm temperatures and increasingly strong southerly winds will
exist across the region ahead of an approaching storm system
through Monday. A strong cold front will sweep through the state
Monday night through Tuesday bringing below normal temperatures
through mid to late week.

&&

.DISCUSSION...Evening satellite imagery shows an upper low lifting
through the southern Rockies while a deeper upstream trough is
noted digging just off the Pacific Coast. Moisture along the back
side of the aforementioned low continues to maintain a diminishing
band of showers spreading into south central Utah, and these
should dissipate over the next hour or so. Otherwise the upstream
trough will move inland overnight into the day Monday resulting in
a substantial increase in winds across much of the area,
particularly across the west deserts. Going forecast and headlines
handle this well. Will make cosmetic adjustments to the going
forecast otherwise no major changes needed at this time.

&&

.AVIATION...Southerly winds and VFR conditions will persist at
KSLC through the overnight hours with gusts in excess of 26 kts
becoming increasingly likely after 08Z.
