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

.DAY ONE...Today and Tonight

The coldest and strongest winter storm of the season will affect
the region through Tuesday. Strong gusty southwest winds are
occurring today and will persist into tonight for some southern
areas ahead of the cold front.

Widespread heavy snow and much colder temperatures will spread
across the outlook area from north to south through tonight. The
cold front could bring near whiteout conditions to the mountain
passes in heavy snow and strong winds for a few hours as it moves
south on Sunday. Snow will taper off many northern areas tonight.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

The snow will re-develop for northern areas Monday and Monday
night, while persisting across the south. The snow could continue
into Tuesday across mountainous locations favored in northwest
flow, as well as locations downwind of the Great Salt Lake and
Utah lake. Accumulating snow will be possible across Dixie and
Lake Powell region Monday into Monday night. By Tuesday afternoon
most areas will have seen a moderate to heavy snowfall.

The very cold temperatures that spread into the outlook area
tonight will continue through Tuesday night into Wednesday. At
this time it looks like Wednesday morning will be the coldest in
this stretch with lows ranging from the low teens to below zero.
Any plants or trees that have starting budding out will be
affected by this cold snap.

.SPOTTER INFORMATION STATEMENT...

conditions according to standard operating procedures.
