Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
121 PM MDT Fri Aug 22 2025
...MONSOON MOISTURE CONTINUES TO INCREASE...
.BROADCAST DISCUSSION...Monsoon moisture will continue to increase
across the area through at least Wednesday, bringing increasing
coverage of showers and thunderstorms, improving humidity, and
higher chances for wetting rain, particularly after Saturday.
.DISCUSSION...Moisture will continue to move into Utah from the
south, with another secondary surge arriving Sunday. Coverage of
showers and thunderstorms will continue to increase. Storms will
become wetter, with increasing chances for wetting rain and
decreasing chances for gusty outflow winds through at least
Wednesday. Relative humidity will also improve accordingly. One
area of forecast uncertainty is the amount of cloud cover, which
may limit the intensity of any developing storms and therefore
rainfall amounts, particularly after Sunday. Model guidance
currently suggests moisture will peak around Wednesday, with a
gradual decrease in moisture thereafter.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
