Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
439 AM MDT Mon Aug 10 2026

...MONSOON PATTERN STAYS IN PLACE...

.BROADCAST DISCUSSION...Monsoonal moisture will continue to
increase statewide through at least midweek, bringing improving
relative humidities, increasingly wet storms, and an increasing
threat of lightning.

.DISCUSSION...High pressure will remain parked over the Four
Corners region through Wednesday. The resultant southerly flow
over Utah will continue to draw deep monsoon moisture northward.
This will result in showers and thunderstorms developing each
afternoon, focused primarily over the higher terrain, with the
storms becoming wetter as the moisture continues to move into the
lower levels. This pattern will bring improvement in relative
humidity values and an increasing chance of wetting rainfall,
though any storms that develop will be capable of producing gusty
and erratic thunderstorm winds as well as lightning. The ridge is
expected to move east for the latter half of the week, though a
relatively moist and unstable pattern is expected to remain over
the area for at least much of the remainder of the week.

***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
