Special Weather Statement, NWS Salt Lake City, UT

Area Forecast Discussion
National Weather Service Salt Lake City UT
1023 AM MDT Sat May 2 2020

.SYNOPSIS...
A series of weather disturbances will bring showers along with a
few thunderstorms to mainly the northern half of Utah and
southwest Wyoming through the weekend. A cold front will cross the
state late Sunday into Monday. High pressure will build into the
region next week.

&&

.DISCUSSION...Per morning radar, the stalled boundary remains
draped across central Utah from northwest Millard county to
northeast Uintah county. Isolated showers and even a few isolated
lightning strikes have been noted earlier this morning associated
with these showers. Temperatures across the state are a handful of
degrees cooler this morning than yesterday, but with some
clearing of clouds this afternoon we should rise a few degrees
warmer than yesterday, which results in just a few degrees above
normal.

Shower and thunderstorm activity this afternoon should become
more widespread across far northeast Utah with the progression of
the shortwave in clusters, where the best instability and mid
level flow reside. Most of the thunder potential should remain in
the Wasatch mountains and points east, however there is a slight
chance of some development along the Wasatch front before moving
east.

The forecast package has this advertised pretty well, so minimal
edits were made.

&&

.AVIATION...VFR conditions expected through the valid TAF period. A
predominate light northerly flow at less than 5 knots may become
variable at times through the afternoon. Mid level clouds will
increase, but should remain above 10k feet AGL. There is a 20%
chance of a thundershower to impact the SLC terminal between
18-21z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
