FIRE WEATHER PLANNING FORECAST FOR UTAH
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
327 AM MDT SUN MAY 17 2026
...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT SUNDAY FOR
WIND AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 497 AND
498...
BROADCAST DISCUSSION
WHILE RH TRENDS UP FOR MOST OF THE STATE
TODAY, CRITICALLY DRY CONDITIONS WITH GUSTY WINDS CONTINUE ACROSS
PORTIONS OF FAR SOUTHERN UTAH THIS AFTERNOON, RESULTING IN A
PERIOD OF CRITICAL FIRE WEATHER CONDITIONS. AN UNSEASONABLY COLD
SYSTEM DROPPING INTO UTAH TODAY BRINGS CHANCES FOR WIDESPREAD
VALLEY RAIN AND MOUNTAIN SNOW THIS AFTERNOON INTO MONDAY MORNING.
DISCUSSION
AN UNSEASONABLY COLD WEATHER SYSTEM IS ON TRACK TO
DROP INTO THE GREAT BASIN TODAY, RESULTING IN MULTIPLE IMPACTS TO
THE STATE THROUGH MONDAY. FIRST, GUSTY WEST-SOUTHWEST WINDS
DEVELOP ACROSS SOUTHERN UTAH THIS AFTERNOON, WITH WIDESPREAD GUSTS
30-40 MPH EXPECTED THROUGH THE EVENING. WHILE THIS SYSTEM IS
EXPECTED TO BRING INCREASING RELATIVE HUMIDITY ACROSS MOST OF THE
STATE, CRITICALLY DRY CONDITIONS WILL REMAIN ACROSS PORTIONS OF
SOUTHERN UTAH THROUGH THIS AFTERNOON, RESULTING IN A PERIOD OF
CRITICAL FIRE WEATHER CONDITIONS ACROSS THE AREA. WIDESPREAD
PRECIPITATION MOVES IN FROM THE NORTH THIS AFTERNOON, GRADUALLY
SPREADING SOUTH THROUGH EARLY MONDAY MORNING BEFORE SHIFTING
EASTWARD OUT OF THE REGION BY THE LATE MORNING. SNOW LEVELS DROP
RAPIDLY THROUGH THIS EVENING, BOTTOMING OUT AROUND 6000 FEET BY
EARLY MONDAY MORNING. MUCH COLDER CONDITIONS PREVAIL BEHIND THIS
SYSTEM ON TUESDAY MORNING, BUT A GRADUAL WARMING AND DRYING TREND
IS EXPECTED TO CONTINUE THROUGH THE REMAINDER OF THE WEEK.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
