Significant accumulations of snow are expected in the southern
and central mountains through tonight. The heaviest snows will
likely occur over the central mountains. Valleys locations,
especially across far southern and southwest Utah, will receive
moderate to locally heavy rain into this evening. This rain will
gradually change to snow in the higher valleys tonight, with some
accumulations over southwest Utah.

Accumulating snow will also occur across the eastern valleys
tonight. The greatest accumulations are expected in Castle
Country and through the western portion of the San Rafael Swell.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Precipitation associated with the Saturday through Saturday night
storm will wind down quickly early Sunday. A second fast moving
storm system will cross the northern portion of the outlook area
late Sunday night through Monday. Colder temperatures and some
light snow are expected across the northern mountains and
adjacent valleys. Gusty north winds will also develop behind the
cold front sweeping south through the outlook area on Monday.

Strong high pressure will develop across the western states by
midweek. Dry conditions are expected with increasing fog and
urban haze during the middle and latter portions of the week.


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