Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
325 AM MDT Sun Aug 10 2025
...ELEVATED TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS
EAST OF I-15 TODAY...
.BROADCAST DISCUSSION...Northwesterly flow will maintain a
warm and dry airmass across the region through Monday, with
elevated to locally critical fire weather conditions likely
across areas east of I-15. High pressure will then bring a
warming trend heading into midweek. By Wednesday, an increase
in moisture will begin a threat for dry thunderstorms.
.DISCUSSION...Northwest flow will reside across the region
today maintaining a warm and dry airmass. Temperatures will
trend several degrees warmer across northern Utah, with
little change across the south. With this dry airmass
remaining in place, RH values will fall below 15 percent
across most lower elevations (below 10% across southern Utah).
As this northwest flow mixes to the surface this afternoon,
gusty winds will result in elevated to locally critical fire
weather conditions across areas east of I-15. In particular
zone 498 as well as western portions of zones 489, and 494
will see wind gusts near 25 mph at times within a favorable
downslope setup. Winds will trend a little lighter on Monday
while the airmass remains warm and dry.
High pressure will build across the region heading into the
midweek period, resulting in hot and very dry conditions by
Tuesday, with poor overnight recovery Tuesday night. This
high will shift a little east by Wednesday, allowing moisture
to begin spreading into the region, resulting in an increasing
chance for lightning during the latter half of the week.
Initially, this moisture will remain elevated resulting in
isolated to potentially scattered dry thunderstorms Wednesday
and Thursday. These storms may transition to wet by the end
of the week if this moisture can remain in place.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
