Area Forecast Discussion
National Weather Service Salt Lake City UT
1001 AM MDT Sat Apr 21 2018

.SYNOPSIS...High pressure aloft will bring a warming and drying
trend for the weekend. A weak weather disturbance will brush
northern Utah Monday.


.DISCUSSION...The low amplitude upper ridge across the Great Basin
will bring warm and dry conditions to the forecast area this
weekend. The next shortwave moving into the Pacific Northwest
Sunday will move east into the northern Rockies/northern Great
Basin late Sunday night/Monday.

Looking at a short period of favorable synoptic conditions to
support precip late Sunday night through Monday morning. During
that period low and mid-level cold advection, weak dynamic lift
with the mid-level trough, and adequate moisture should be
sufficient for light showers across far northern Utah/southwest

The aforementioned trough will slow it`s eastward progression and
develop a weak circulation center over the northern Plains by
Tuesday. The wrap around on the back side of this feature will
likely clip southwest Wyoming, resulting in a few additional
showers through early Tuesday afternoon.

No updates planned this morning.


.AVIATION...Winds at the SLC terminal are expected to switch to the
northwest between 16-18Z.
