FIRE WEATHER PLANNING FORECAST FOR UTAH
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1239 PM MDT SUN SEP 13 2026
..COOLER TEMPERATURES IN THE NORTH BEGINNING MONDAY
BROADCAST DISCUSSION
ANOTHER ROUND OF ISOLATED THUNDERSTORMS
CAPABLE OF HEAVY RAIN IS OCCURRING ACROSS THE SOUTHEAST AT THIS
TIME. MEANWHILE A DRY COLD FRONT MOVING THROUGH NORTHERN AND
CENTRAL UTAH THROUGH MONDAY WILL BRING A TRANSITION TO
NORTHWESTERLY WINDS ALONGSIDE COOLER TEMPERATURES.
DISCUSSION
WIDESPREAD GUSTY SOUTHERLY WINDS EXIST THIS
AFTERNOON AS A COLD FRONT IS SLOWLY TRACKING IN FROM THE
NORTHWEST. THE STRONGEST WINDS EXIST ACROSS WESTERN UTAH IN
ADVANCE OF THIS FRONT, WITH CURRENT LOCATION OF THE FRONT DRAPED
FROM SW-NE ACROSS THE GREAT SALT LAKE. COOLER TEMPERATURES AND A
PERIOD OF GUSTY NORTHWEST WINDS WILL MOVE IN BEHIND THE FRONTAL
PASSAGE PRIOR IT STALLING ACROSS CENTRAL UTAH IN ROUGHLY 24 HOURS
TIME. SOUTH OF THIS FRONT, GUSTY SOUTHWESTERLY WINDS WILL REMAIN
IN PLACE.
MONSOONAL MOISTURE CONTINUES TO FOCUS ACROSS SOUTHEASTERN UTAH
TODAY, AND THIS TREND WILL CONTINUE THROUGH EARLY THIS WEEK.
CURRENTLY THIS MOISTURE IS MOST PREVALENT FROM FWZ 498 NORTHEAST
THROUGH FWZ 489, AND THESE WILL BE THE PRIMARY AREAS FOR ISOLATED
THUNDERSTORMS CAPABLE OF HEAVY RAINFALL IN THE SHORT TERM. DUE TO
THE FRONT MOVING INTO CENTRAL UTAH OVER THE NEXT 24 HOURS, THIS
ZONE OF THUNDERSTORM POTENTIAL IS EXPECTED TO SHIFT SLIGHTLY EAST
EARLY WEEK.
A GRADUAL WARMING TREND IS EXPECTED TO BEGIN ON TUESDAY ACROSS
THE NORTHERN HALF OF DISTRICT, BUT TEMPERATURES ARE ONLY EXPECTED
TO REBOUND TO NEAR SEASONAL NORMALS MID/LATE WEEK. MONSOONAL
MOISTURE HAS THE POTENTIAL TO SPREAD ACROSS MUCH OF
CENTRAL/SOUTHERN PORTIONS MID TO LATE WEEK, BUT CONFIDENCE REMAINS
LOWER THAN NORMAL AT THIS TIME.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
