Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
125 AM MDT Sun Aug 17 2025
...HOT AND DRY THROUGH EARLY NEXT WEEK...
.BROADCAST DISCUSSION...A hotter, drier airmass will build into
the region today, with locally elevated fire weather conditions
across portions of southwest and west central Utah. Very dry
daytime humidities with poor overnight recoveries can be expected
Monday and Tuesday before moisture begins to increase from west to
east Wednesday into Thursday.
.DISCUSSION...As high pressure continues to build into the region,
expect the bulk of the area to see increasing temperatures and
drier conditions today. Locally elevated fire weather conditions
can be expected in windier spots of west central and southwestern
Utah this afternoon and evening. Humidities will fall to single
digits by Monday across many lower elevation locations, with poor
overnight recoveries. These hot and very dry conditions will
continue through Tuesday.
By Wednesday, moisture will begin to increase across western
Utah, reaching eastern Utah by Thursday. In association with this
monsoon surge, expect increasing threat of thunderstorms with
wetting rains Friday into early next week.
***Thunderstorms imply strong, gusty and erratic winds***
