Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
326 AM MDT Sat Aug 30 2025
...WARMING AND DRYING THROUGH TUESDAY, MOISTURE INCREASING WEDNESDAY FORWARD...
.BROADCAST DISCUSSION...Today will mark the beginning of a warming
and drying trend that is expected to persist through Tuesday,
bringing Utah back into a relatively short lived dry period. From
about Wednesday forward, anticipate a gradual increase in moisture
to bring increasing chances for showers and thunderstorms
alongside little change in day to day temperatures.
.DISCUSSION...High pressure building over the Great Basin region will
aid in a warming and drying trend through early next week.
Throughout this warming trend, daily high temperatures are
expected to warm back to slightly above normal levels by early
next week. Until then, near to slightly below-normal temperatures
will remain in place through the weekend. A stout decrease in
afternoon humidity is expected to spread across Utah under the
influence of the ridge of high pressure, with afternoon minimum
values dropping back into the 15 to 25 percent range by Saturday
afternoon and 10 to 20 percent by Sunday. Afternoon minimum
humidity of 10 to 20 percent is expected to persist through at
least Tuesday, with a gradual increase expected through the
remainder of the week. Overnight recovery, however, is expected to
be fair to good across a majority of Utah with the exception of
the lowest elevations across southern Utah (i.e. lower Washington
Co., Glen Canyon NRA) and thermal belts west of the I-15 corridor
(25 to 30 percent recovery expected).
Mid-week forward anticipate chances for showers and isolated
thunderstorms to work back into the daily forecast as moisture
gradually increases. As we head into next weekend, shower and
thunderstorm chances will spread farther north while chances for
wetting rains will also see a notable increase as overall moisture
continues to increase. Outside of any outflow winds, expect winds
to be generally light and terrain driven each day.
