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

.DAY ONE...Today and Tonight

Showers and isolated thunderstorms will develop across the
northern portion of the outlook area today through this evening.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Significantly warmer temperatures are expected across the entire
outlook area through the end of the week. A few afternoon mountain
showers or thunderstorms are possible both Thursday and Friday.

A low pressure system will move off the eastern Pacific and into
California late Friday. This low pressure will continue east into
the Great Basin where it will remain through the holiday weekend.

Showers and thunderstorms associated with this low pressure system
will expand into the mountains and western valleys of Utah late
Saturday. These showers and storms will become more widespread
Sunday and Monday. By Tuesday most of the shower and thunderstorm
activity will shift north into northern Utah and southwest
Wyoming. Snow levels will remain on the high side, though short
periods of high elevation snow are possible during periods of
intense precipitation.

Temperatures on Saturday will begin to trend downward, though
readings are expected to remain above late May normals across the
outlook area. For Sunday and Monday readings will fall to near or
below seasonal norms before warming up again heading into the
middle of the week.

.SPOTTER INFORMATION STATEMENT...
