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

.DAY ONE...Today and Tonight

Moisture surging north out of Arizona will bring increasing clouds
and a few showers to far southern Utah late this afternoon.

Valley rain and mountain snow will expand north and east across
the southern half of the outlook area this evening, then into
northeast Utah later tonight. Accumulating snows are expected
across the higher elevations, with moderate to brief heavy rains
in the lower valleys of extreme southern Utah later tonight. Local
areas of flooding could develop in the heavier rains across
extreme southwest Utah overnight.


.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A strengthening low pressure system will move out of California
and track slowly east across the southern portion of the outlook
area Wednesday through Thursday. This low pressure will bring a
fairly long duration precipitation event to the area with heavy
snows at the higher elevations of southern, central and northeast
Utah. Accumulations exceeding a foot will be common, with the
heaviest snows across the southern mountains. The lower valleys
of extreme southern Utah will see the potential for heavy rain and
the possibility of localized flooding through Wednesday evening.

Precipitation will begin to wind down late Thursday as the low
pressure system presses east out of Utah. Cold temperatures will
persist across the outlook area in early Friday. A gradual warming
and drying trend will commence late Friday and continue through
the upcoming weekend.

.SPOTTER INFORMATION STATEMENT...

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