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

.DAY ONE...Today and Tonight

Valley rain and mountain snow will decrease across northern Utah
and southwest Wyoming this morning through early this afternoon.

The next in the series of weather disturbances impacting northern
Utah will arrive for late this afternoon through the overnight
hours. Light valley rain and mountain snow will return to far
northern late this afternoon, then turn heavier as it expands
across much of northern Utah and southwest Wyoming tonight.
Significant snow accumulations are expected, with rain or a rain
and snow mix in the northern Utah valleys and snow over southwest

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Winter storm conditions will continue across much of the northern
half of the outlook area into Saturday. Heavy snow is expected
for the northern mountains which will have a significant impact on
travel through Saturday morning. Valley locations will transition
to all snow early Saturday.

Colder air pouring into the area from the northwest will force
precipitation south into southern Utah Saturday. This precipitation
will start as rain on Saturday, then transition to snow Saturday
night. The heaviest precipitation will settle into far southern
Utah with significant snow accumulations possible across the
southern mountains. Accumulating snows will be possible across the
west-central and southwest Utah valleys, with rain or a rain and
snow mix expected for the valleys near the Arizona border.

Snow showers will continue across southern Utah, with cold
temperatures and lingering snow showers across the remainder of
the outlook area Sunday. High pressure aloft will gradually bring
dry conditions back to the area during the first half of the week.


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