Fire Weather Planning Forecast for Utah

307 AM MDT Mon Sep 1 2025
...WARM AND DRY THROUGH TUESDAY, INCREASING MOISTURE THEREAFTER...
.BROADCAST DISCUSSION...Warming and drying will continue through Tuesday
as a dry region of high pressure remains in place. Moisture
gradually increases through the second half of the week, bringing
increasing chances for showers and thunderstorms, especially by
the weekend.
.DISCUSSION...High pressure remains in place over the area, aiding
in warming temperatures and a drying surface environment across
Utah through at least Tuesday. In addition to the warm and dry
conditions, winds will remain generally light and terrain driven.
Overall, the biggest fire weather concern will be the very dry
conditions that will resurface on Monday and Tuesday. Afternoon
minimum humidity will fall into the 10 to 20 percent range during
the daytime hours, and see fair to good recovery during the
overnight hours with the exception of the thermal belts across the
western half of Utah. With strong afternoon heating pairing with
subtle amounts of mid-level moisture, chances for showers and an
isolated thunderstorm over the high Uintas will be very low, but
not zero. Moisture increases gradually from about Wednesday
forward from south to north, bringing increasing chances for
showers and thunderstorms across Utah. Initially, chances for
wetting rains will be relatively low, but will increase more
substantially as we head into the weekend as moisture is expected
to peak by Saturday/ Sunday. Additionally, as a deeper southwest
flow develops over the weekend, anticipate an uptick in afternoon
winds over the weekend, particularly across the southern and
western half of Utah.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
