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

.DAY ONE...Today and Tonight

A weak cold front will sag south into extreme northern Utah today.
This front will bring slightly cooler temperatures and a few
showers to the Idaho border region this afternoon through the
overnight hours.

Temperatures across southern and central Utah will continue to
climb under a dry and warm westerly flow aloft today.

Remember...swift and very cold flows continue along the waterways
of northern Utah and southwest Wyoming. exercise caution in areas
adjacent to waterways that are fed by high elevation snowmelt.
These fast and cold waterways are deadly, as a person or pet can
drown in less than a minute in these waters.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

A somewhat stronger weather disturbance will bring clouds,
additional light showers and isolated thunderstorms along with
still cooler temperatures to northern Utah and southwest Wyoming
on Saturday. Southern Utah will remain dry and warm with
temperatures little changed from Friday.

High pressure aloft will strengthen across the interior west
beginning Sunday. Very hot temperatures for mid-June will develop
across the southern portion of the outlook area early next week.
Triple digit readings will be common across extreme southern
through east-central Utah. These hot temperatures could turn
dangerous for people engaging in outdoor activities or for those
who do not have adequate cooling in their homes or businesses. The
remainder of the outlook area will see temperatures between 10 and
15 degrees above normal during the first half of the upcoming week.

Remember...Waterways across northern Utah and southwest Wyoming,
though flows will be decreasing, will continue to be dangerous
with cold and fast flows expected through the outlook period.

.SPOTTER INFORMATION STATEMENT...

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