Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
322 AM MDT Sun Aug 24 2025
...MONSOON MOISTURE STAYS THROUGH MIDWEEK...
.BROADCAST DISCUSSION...Monsoon moisture will remain over the area
through the middle of the upcoming week. This will bring
increasing coverage of showers and thunderstorms, improving
relative humidity values, and higher chances for wetting rain.
.DISCUSSION...Deep moisture will continue to make its way into
Utah during the early part of the week. As a result, coverage of
showers and thunderstorms will increase, particularly during the
afternoon and evening, with increasing relative humidity values
and decent chances of wetting rains. Temperatures will become less
warm, up to 10F below seasonal normals by midweek, with winds
staying light and terrain driven away from thunderstorms. The
airmass will start to dry for the latter half of the upcoming
week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
