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

.DAY ONE...This Afternoon and Tonight

Scattered showers and isolated thunderstorms will persist in
association with the weather disturbance moving southeast across
Utah this afternoon. Showers and storms will wind down quickly in
the wake of this disturbance, with remaining precipitation ending
by midnight tonight.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

High pressure aloft building into the outlook area during the
first half of the week will drive temperatures above late May
norms and bring dry conditions to the area. A number of waterways
will see increasing flows as the snowmelt runoff accelerates. Keep
children and pets away from these fast flowing waterways.

The next Pacific storm system will impact the outlook area late
Wednesday through the end of the week. Cooler temperatures and
occasional precipitation is expected, with most of the cooler and
wet weather across the northern half of the outlook area.

.SPOTTER INFORMATION STATEMENT...

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