HIGH PRESSURE WILL REMAIN IN A FAVORABLE LOCATION TO

ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WITH THE THREAT OF

WILL CONTINUE TO BE SLOT CANYONS, NORMALLY DRY WASHES, SLICK ROCK
AREAS AS WELL AS RECENT BURN SCARS.
LOOKING AHEAD, THE WEATHER PREDICTION CENTER HAS UTAH OUTLOOKED IN
A MARGINAL RISK FOR FLASH FLOODING THROUGH THE NEXT 5 DAYS...AND

KSLC, ISSUED 524 AM MDT MON AUG 10 2026...
THE SLC TERMINAL WILL SEE VFR CONDITIONS
THROUGHOUT THE DAY WITH SOME SCATTERED CLOUDS. SOUTHERLY WINDS ARE
EXPECTED TO SHIFT TO THE NORTHWEST BETWEEN 19Z AND 21Z. THERE IS A
30 PERCENT CHANCE THAT SHOWERS IN THE VICINITY OF THE TERMINAL WILL
BRING PERIODS OF GUSTY AND ERRATIC WINDS, WITH THIS MOST LIKELY TO
OCCUR DURING THE LATE AFTERNOON AND EARLY EVENING.
REST OF UTAH AND SOUTHWEST WYOMING...VFR CONDITIONS ARE EXPECTED
ACROSS THE AIRSPACE THROUGHOUT THE DAY. SCATTERED SHOWERS AND
THUNDERSTORMS WILL DEVELOP AGAIN LATER TODAY, WITH THE GREATEST
COVERAGE IN THE LATE AFTERNOON AND EARLY EVENING POCKETS OF HEAVY
RAIN AND GUSTY WINDS MAY BRING BRIEF TEMPORARY MVFR VISIBILITIES AND
CEILINGS THAT COULD RESULT IN TEMPORARY MOUNTAIN OBSCURATIONS.
OUTSIDE OF SHOWERS AND THUNDERSTORMS, GENERALLY LIGHT DIURNAL WINDS
CAN BE EXPECTED. LOCALLY REDUCED VISIBILITY IN SMOKE WILL OCCUR NEAR
SEVERAL LARGE WILDFIRES INCLUDING NEAR RICHFIELD, NEAR CEDAR CITY,
NEAR MORGAN, AND BETWEEN EPHRAIM AND HUNTINGTON.
FIRE WEATHER
THE MONSOON PATTERN REMAINS IN PLACE FOR THE REMAINDER
OF THE WEEK. THIS MOISTURE WILL PRIMARILY BE FOCUSED ACROSS THE
SOUTHERN 2/3RDS OF THE AREA THROUGH MIDWEEK BEFORE A TROUGH MOVING
IN FROM THE WEST HELPS TO DEVELOP MORE CONVECTION ACROSS THE NORTH
THURSDAY AND FRIDAY. TEMPERATURES WILL ALSO DECREASE BY 10-15 DEGREES
BY THE END OF THE WEEK. NOCTURNAL CONVECTION WILL BE POSSIBLE THROUGH
THE WEEK, BUT DETAILS WILL LIKELY REMAIN UNCERTAIN ON WHERE AND WHEN
UNTIL THE DAY OF ANY NOCTURNAL ACTIVITY AS THESE FEATURES ARE USUALLY
BASED ON HOW THE CONVECTION EVOLVES DURING THE DAY.
THIS TROUGH WILL BRING SLIGHTLY DRIER AIR TO THE REGION FOR THIS
WEEKEND WHICH WILL REDUCE THE FLASH FLOODING PROBABILITIES. IT WILL ALSO
SLIGHTLY INCREASE SOUTHWESTERLY WINDS THURSDAY AND FRIDAY, BUT THE
MAGNITUDE OF THESE WINDS CURRENTLY LOOK TO REMAIN BELOW 30 MPH.
SLC WATCHES/WARNINGS/ADVISORIES
