DISCUSSION, ISSUED 1046 PM MDT TUE JUN 30 2026
A MEAN LONGWAVE TROUGH REMAINS IN PLACE OVER THE
WESTERN CONUS THIS EVENING. AN EMBEDDED SHORTWAVE TROUGH CROSSED
UTAH TODAY AND IS CURRENTLY EJECTING NORTHEAST INTO COLORADO AND
WYOMING. SHOWERS ASSOCIATED WITH THIS SHORTWAVE TROUGH EARLIER
TODAY HAVE MOSTLY DISSIPATED AND AS SUCH, CAN EXPECT MOSTLY CLEAR
SKIES ACROSS A MAJORITY OF THE FORECAST AREA TONIGHT.
ADDITIONALLY, GUSTY WINDS ASSOCIATED WITH SAID SHORTWAVE ALSO
PRODUCED CRITICAL FIRE WEATHER CONDITIONS ACROSS PORTIONS OF EAST-
CENTRAL UTAH TODAY. THE WINDS HAVE SINCE DECREASED AS WELL, AND
THE RED FLAG WARNING HAS BEEN ALLOWED TO EXPIRE.
THROUGH THE REST OF THE WEEK, THE MEAN LONGWAVE TROUGH WILL REMAIN
SETTLED NEARLY IN PLACE. ADDITIONAL WEAK EMBEDDED DISTURBANCES WILL
CONTINUE TO EJECT OUT OF THIS LONGWAVE TROUGH, SOME OF THESE
CROSSING SOUTHERN UTAH AND OTHERS GRAZING NORTHERN UTAH, BUT ALL
WEAKER THAN THE ONE THAT CROSSED THE AREA TODAY. THIS UNSETTLED
PATTERN WILL MAINTAIN A FEW GENERALLY WEAK SHOWERS AND
THUNDERSTORMS ACROSS MAINLY NORTHERN UTAH THROUGH AT LEAST FRIDAY.
WITH SOUTHWESTERLY FLOW REMAINING IN PLACE, AT LEAST LOCALIZED TO
MARGINALLY CRITICAL FIRE WEATHER CONDITIONS WILL CONTINUE THROUGH
THE WEEK ACROSS EAST-CENTRAL UTAH. THESE CONDITIONS MAY BECOME MORE
WIDESPREAD BY FRIDAY WHICH MAY WARRANT CONSIDERATION FOR FIRE
WEATHER HIGHLIGHTS ON FUTURE SHIFTS.
OTHERWISE, EXPECT TEMPERATURES TO GRADUALLY TREND WARMER THROUGH THE
WEEK. BY THE WEEKEND, THE MEAN LONGWAVE TROUGH IS FORECAST TO
WEAKEN, LEAVING UTAH IN MORE OF A WEAK ZONAL FLOW PATTERN BEFORE
TRANSITIONING TO HIGH PRESSURE CENTERED NEAR THE FOUR CORNERS AREA
FOR THE FIRST HALF OF NEXT WEEK. TEMPERATURES OVER THE NEXT 7
DAYS ARE LIKELY TO BE WARMEST UNDER THIS HIGH PRESSURE (25% CHANCE
OF REACHING 100 DEGREES AT SLC MONDAY AND TUESDAY), ESPECIALLY
SINCE SIGNIFICANT MONSOONAL MOISTURE IS NOT FORECAST TO MAKE IT
INTO THE AREA YET. MANY VALLEY AREAS WILL SEE HIGH TEMPERATURES IN
THE MID TO UPPER 90S (OVER 100 DEGREES IN LOWER WASHINGTON COUNTY
AND THE LAKE POWELL AREA) DURING THE FIRST HALF OF NEXT WEEK,
WHICH WOULD BE AROUND 4-8 DEGREES ABOVE NORMAL FOR THIS TIME OF
YEAR.

WILL PREVAIL ACROSS THE AREA OVERNIGHT. VFR CONDITIONS WITH GENERAL
SOUTH TO SOUTHWEST WINDS CAN BE EXPECTED ACROSS THE AREA WEDNESDAY.
SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ACROSS NORTHERN
UTAH WEDNESDAY AFTERNOON. THE CHANCE ONE OF THESE STORMS IMPACT A
NORTHERN TERMINAL IS LESS THAN 20%.
FIRE WEATHER
DEEP SOUTHWEST FLOW WILL REMAIN IN PLACE
THROUGH AT LEAST THE WEEKEND ACROSS UTAH. CONDITIONS WILL BECOME
INCREASINGLY DRY, WITH OVERNIGHT RECOVERIES BECOMING POOR TO VERY
POOR FRIDAY INTO THE WEEKEND. EXPECT ELEVATED TO LOCALLY CRITICAL
CONDITIONS EACH AFTERNOON AND EVENING, PARTICULARLY ACROSS EASTERN
AND SOUTHERN UTAH THROUGH AT LEAST SATURDAY.
MID-LEVEL MOISTURE MAY INCREASE MONDAY INTO TUESDAY, ALLOWING FOR
A PERIOD OF HIGH-BASED CONVECTION AFTER A HOT, DRY STRETCH.
