This hazardous weather outlook is for eastern Utah and western
Colorado.

.DAY ONE...Today and Tonight

Thunderstorm development this afternoon will favor the central and
southern mountains becoming more isolated to the norther. Storms
will again drift southward and the southern San Juan valleys are
most likely to be impacted. 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...Monday through Saturday

Afternoon thunderstorm development will be possible each day
favoring the mountains through the early week period. Another
push of monsoonal moisture arrives by mid-week which will bring
an uptick in thunderstorm coverage. 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 by Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected today or tonight, however
spotters are encouraged to report strong wind gusts and heavy
rainfall amounts to the National Weather Service in Grand
Junction.
