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

.DAY ONE...Today and Tonight

The cold and unstable northwest flow will maintain snow showers
in the Salt Lake City area south into central Utah this morning.

Snow showers will increase in areal coverage across southwest
Wyoming and portion of northern and western Utah this afternoon
through the overnight hours. Light accumulations of snow are
possible across southwest Wyoming and along the I-15 corridor in
west-central through southwest Utah

A cold front front sweeping south across the state this afternoon
will generate strong northerly winds in it`s wake over Washington
county tonight. The strongest winds will be in the north to south
canyons where winds could gust well into the 50 mph range.

A second area of concern for winds will be along the northern
Wasatch Front. Easterly winds out of Wyoming will support the
development of canyons winds overnight. Gusts in excess of 35 mph
are possible in the canyons of Davis and Weber counties.


.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Strong canyon winds in Washington county will gradually decrease
Saturday morning. A similar trend will be observed with the canyon
winds along the northern Wasatch Front.

High pressure aloft to the west will bring somewhat drier and
warmer conditions to the outlook area Sunday and into early next
week. This warming trend will accelerate midweek as the high
pressure shifts east into the Great Basin.

.SPOTTER INFORMATION STATEMENT...

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