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

.DAY ONE...Today and Tonight

A cold front moving through northern Utah and southwest Wyoming
will generate widespread valley rain and mountain snow early this
morning. This front will weaken beginning mid-morning, with just
lingering showers across mainly the higher terrain through the

Across far southern Utah showers and thunderstorms early this
morning will generate moderate to locally heavy valley rain and
mountain snow. This precipitation will impact travel, especially
across the higher terrain where a couple of inches of snow could
accumulate on road surfaces in a short period of time.

Precipitation will dissipate across all but the extreme northern
portion of the outlook area this evening.

Rivers across southern Utah are expected to run high due to the
recent heavy rainfall. River flooding is not expected at this
time. However, flash flood prone areas of southern Utah could see
localized flash flooding through this morning.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

The next storm system will bring colder air to northern and
western Utah over the weekend. The mountains and some of the
higher valleys will receive accumulating snows, with portions of
the Wasatch and Uinta ranges potentially picking up significant
accumulations through the weekend.

Precipitation will shift south into southern and central Utah
by early next week. Valley rain and mountain snow will exist
through early Tuesday. Accumulating snows are expected across the
higher terrain, though the amounts will remain on the low side.

Strong high pressure aloft developing to the west of Utah will
bring mostly dry and increasingly warm conditions to the outlook
area midweek.


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