This hazardous weather outlook is for eastern Utah and western

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorm development is possible over a
majority of Eastern Utah and Western Colorado over the next 24
hours. Gusty outflow winds remain a threat with gusts of 35 to 45
mph possible in some of the storms. Localized areas of heavy rain
also possible in the south which could lead to some runoff
problems. Lightning will always be the highest threat.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Afternoon thunderstorm favoring the terrain on Tuesday will see an
uptick Wednesday as a push of monsoonal moisture arrives. Any
thunderstorm will be capable of producing gusty outflow winds,
heavy rain, small hail and dangerous cloud-to- ground lightning.
Localized flooding may also become more a threat with the push of
moisture for the latter half of the week.


Spotter activation is not expected today or tonight, however
spotters are encouraged to relay rainfall amounts or any observed
flooding to the National Weather Service in Grand Junction.
