Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
329 PM MDT Sun Aug 24 2025
...MODERATED FIRE WEATHER CONDITIONS THROUGH THURSDAY, THEN DRYING...
.BROADCAST DISCUSSION...Monsoonal moisture will remain in place across
Utah through at least Wednesday/ Thursday, bringing moderated fire
weather conditions across the region and daily chances for showers
and thunderstorms producing wetting rains. Conditions gradually become
warmer and drier from Friday forward as a dry airmass is introduced
to Utah once again.
.DISCUSSION...
Moderated fire weather conditions are expected across the
entirety of Utah through at least Wednesday as monsoonal moisture
remains in place over the eastern Great Basin region. Each day
through Wednesday/ Thursday, afternoon showers and thunderstorms are
expected, bringing higher chances of wetting rains. If an
individual area does not receive wetting rains, afternoon humidity
will be significantly moderated as we peak in moisture on Monday
and Tuesday. Afternoon minimum humidity values are expected to be
between 25 and 40 percent for a majority of Utah through at least
Thursday.
From Friday forward, anticipate an overall drying of the
environment across Utah as a dry westerly flow begins to work into
the region. Alongside this drying trend, anticipate temperatures
warming through this period as well. That said, daytime high
temperatures are still expected to remain below climatological
normals for this time of year. With any lingering moisture in the
lower levels, isolated showers and thunderstorms are anticipated
to develop over the high terrain across the state of Utah, with
a chance for dry lightning, though coverage of any dry lightning
is expected to be fairly minimal. While daytime minimum humidity is
expected to drop back into the 15-25 percent range, overnight
humidity recovery is still expected to be fair to good as values
recover to between 45 and 55 percent.
