Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
307 AM MDT Fri Oct 17 2025
NOTICE TO ALL USERS: The final routine Fire Weather Forecast for
the 2025 season will be issued the afternoon of Saturday
October 18. NFDRS trend forecasts and the Smoke Management Forecast
will also end at that time. An automated version
of the Fire Weather Forecast will continue to be issued throughout
the cool season for planning purposes. Spot Forecasts will remain
available at any time through the normal Spot Forecast request procedures.
...DRYING AND WARMING THROUGH SUNDAY, GRAZING COLD FRONT SUNDAY NIGHT...
.BROADCAST DISCUSSION...High pressure reestablishes over the region bringing
a warming and drying trend through Sunday. A storm system will
graze northern Utah Sunday night, bringing a dry cold front into
at least the northern half of the state.
.DISCUSSION...As the previous storm system continues to exit the region,
increasingly stable conditions will build back into place across
Utah through the next 24 hours. Cooler overhead temperatures will
linger across the area, leading to below-normal temperatures and
generally higher humidity alongside northwest winds overhead. For
northern Utah, these northwesterly winds will be evident over the
higher terrain while the central and southern area will see flows
dominated by terrain features.
Through Sunday, anticipate an areawide warming and drying trend
as high pressure controls a majority of Utah. By Sunday afternoon,
temperatures will see a stout increase from where we are now,
pushing temperatures back to above normal levels by upwards of
5-10 degrees across the western valley areas. Additionally,
humidity will reach its lowest point across the area as some of
the western Utah valleys (particularly southwest Utah) reach as
low as 15-20 percent. For the areas north of the Juab-Tooele
County line, humidity values are expected to bottom out between
25-35 percent. By Sunday evening, a grazing storm system to the
north will help to bring an increase in south to west flow for the
northern Utah mountains. There is generally high confidence that
a largely dry cold front will move across northern Utah Sunday
night/ Monday morning, becoming much weaker as it progresses into
west-central Utah.
