...MONSOON MOISTURE REMAINS THROUGH END OF WEEK...
.BROADCAST DISCUSSION...Monsoon moisture will remain in place,
particularly across southern and eastern Utah through Friday.
Southwest winds will remain breezy 25-35 mph across
western Utah, although min RH should remain above 20% for most
locations. Cooler and drier conditions return by the weekend.
.DISCUSSION...
Monsoon moisture will remain in place keeping humidity elevated
through the end of the week. Flood watches are in place across
much of southern and eastern Utah due to the threat of locally
heavy rainfall today through Thursday. Moisture will linger into
Friday, but drier air will start to work in from the west, again
limiting the best heavy rain threat to eastern Utah. Other than
the heavy rain threat, any thunderstorms are capable of producing
gusty and erratic winds, lightning, and small hail. By Saturday
into Sunday, a cold front will cross the state brining cooler
temperatures and drier conditions again. Looking farther ahead,
ensembles are in good agreement about a cutoff low settling in
near Las Vegas, which would help bring moisture northward into
southern Utah again as early as Monday, and supporting shower and
thunderstorm chances again next week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
