Area Forecast Discussion
National Weather Service Salt Lake City UT
935 AM MST Sun Nov 19 2017

.SYNOPSIS...High pressure aloft will remain over the region
today. A weak weather disturbance will graze northern Utah on
Monday, followed by the return of high pressure by midweek.


.DISCUSSION...The forecast area is under a roughly zonal flow this
morning, resulting in generally dry and stable conditions. A very
weak wave moving through the ridge in place is resulting in some
high clouds over northern and central Utah and little else.
Overall, looking at a warming trend for much of Utah, though
valley inversions will limit warming for locations like the
Wasatch Front, Cache Valley, Bear River Valley, and southwest

An ill-defined Pacific Northwest shortwave is still on track to
graze northern Utah and southwest Wyoming during the day Monday,
bringing some moisture along with it. However, the shortwave
energy itself is very unimpressive (particularly in the EC),
though there is a bit of jet support. The main impact will be to
increase cloud cover over northern portions of the forecast area,
though there should be some light precip during the day Monday,
primarily near the Utah/Idaho border.

Behind that exiting wave, high pressure is expected to make a
quick return on Tuesday, continuing to build at least through the
work week. This will result in a steady warming trend with
generally tranquil conditions.

No updates expected to the forecast this morning.


.AVIATION...Winds at the SLC terminal are expected to switch to the
northwest around 19-21Z, though periods of light and variable winds
are also possible through the day.
