This Hazardous Weather Outlook is for the western two thirds of
Utah and southwest Wyoming.

.DAY ONE...Today and Tonight

A plume of moisture extending from south-central through
northeast Utah will spawn scattered showers along with a few
thunderstorms today through this evening. Locally heavy rains are
possible across far southern Utah, with the potential for
localized flash flooding in the flood prone areas of far southern
Utah.

Eclipse viewing today will be the best across far western and
northern Utah and southwest Wyoming where cloud cover will be
limited. Extensive cloud cover as a result of the moisture plume
will limit viewing of the eclipse from south-central Utah north
into northeast Utah.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Shower and thunderstorm activity will increase in areal coverage
and expand northward as moisture pushes north across the outlook
area. Showers and storms will concentrate across northern Utah
late Tuesday night and Wednesday.

Drier air working into southern Utah midweek will bring a decrease
in shower and thunderstorm activity through the upcoming weekend.
These showers and stroms will also show a decreasing trend across
the remainder of the outlook area through the weekend.

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report significant weather
conditions according to standard operating procedures.
