NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1252 PM MDT SAT MAY 16 2026
...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT THIS EVENING
FOR WIND AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 489,
494, AND 495...
...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
GUSTY SOUTHERLY WINDS COMBINED WITH VERY
DRY CONDITIONS WILL BRING AREAS OF CRITICAL FIRE WEATHER
CONDITIONS TO THE VALLEYS OF SOUTHERN UTAH TODAY. RELATIVE
HUMIDITY WILL INCREASE SUNDAY, BUT FAR SOUTHERN UTAH WILL STILL
REMAIN CRITICALLY DRY. AN UNSEASONABLY COLD STORM SYSTEM WILL
BRING ACCUMULATING MOUNTAIN SNOW AND MUCH COOLER TEMPERATURES
SUNDAY INTO MONDAY.
DISCUSSION
AN INITIAL WEAK COLD FRONT HAS MOVED INTO CENTRAL
UTAH. WINDS AHEAD OF THE FRONT WILL BECOMING INCREASINGLY BREEZY
AS RELATIVELY HUMIDITY VALUES REMAIN VERY LOW, SO SOUTHERN UTAH
WILL SEE AREAS OF CRITICAL FIRE WEATHER CONDITIONS AND A RED FLAG
WARNING IS IN EFFECT. SCATTERED SHOWERS AND A FEW HIGH BASED
STORMS WILL DEVELOP THIS AFTERNOON, PRIMARILY ALONG THE FRONTAL
BOUNDARY. ANY STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING
GUSTY AND ERRATIC WINDS AS WELL AS ISOLATED DRY LIGHTNING. THE
MAIN STORM SYSTEM WILL CROSS THE AREA SUNDAY AFTERNOON THROUGH
MONDAY, BRINGING MUCH COLDER TEMPERATURES, AND ACCUMULATING SNOW
TO THE HIGHER TERRAIN OF UTAH. WINDS WILL REMAIN ELEVATED OVER
SOUTHERN UTAH, AND WHILE RELATIVE HUMIDITIES WILL BE INCREASING,
THEY WILL REMAIN CRITICALLY LOW OVER FAR SOUTHERN UTAH, WHERE A
RED FLAG WARNING WILL REMAIN IN EFFECT TOMORROW. BEHIND THE
EXITING SYSTEM, CONDITIONS WILL TREND DRIER AND WARMER FOR THE
REMAINDER OF THE UPCOMING WEEK.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
***ALL WINDS ARE 20 FOOT, 10-MINUTE AVERAGES***
