- ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS SOUTHWESTERN AND

WILL BE POSSIBLE WITH ANY THUNDERSTORMS ACROSS SOUTHWESTERN
UTAH.
- ELEVATED TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS WILL OCCUR

DISCUSSION, ISSUED 1014 PM MDT FRI AUG 14 2026
AFTER AN ACTIVE WEEK OF MONSOON MOISTURE DRIER AIR IS BEGINNING TO
PUSH INTO THE AREA FOR THE WEEKEND. A FEW STORMS NEAR THE IDAHO
BORDER CONTINUE TO PUSH TO THE EAST AND WEAKEN. THESE WILL
DISSIPATE LATER THIS EVENING WITH A MUCH QUIETER PATTERN
DEVELOPING.
A RIDGE WILL STAY CENTERED OVER THE SOUTHERN GREAT PLAINS THROUGH
EARLY NEXT WEEK WITH A LIGHT WEST/SOUTHWEST FLOW ALOFT AND LOWER
PWATS SIGNALING THE MONSOON MOISTURE TAP HAS BEEN WEAKENED. GIVEN
THE WIDESPREAD PRECIPITATION THAT HAS FALLEN OVER THE LAST WEEK
THERE REMAINS SOME LOW LEVEL MOISTURE NEAR THE SURFACE THAT WILL
HELP TO INITIATE SOME DIURNAL CONVECTION OVER THE NEXT SEVERAL
DAYS PRIMARILY ACROSS TERRAIN, BUT EVEN THIS REMAINS <20% CHANCE
OF OCCURRENCE. TEMPERATURES WILL GRADUALLY START TO WARM THIS
WEEKEND, BUT STILL REMAIN 5-8 DEGREES BELOW NORMALS FOR THIS TIME
OF YEAR.
THE MOST NOTABLE SYNOPTIC FEATURE OVER THE NEXT WEEK WILL COME IN
THE FORM OF A SHORTWAVE MOVING THROUGH THE PNW AND UPPER
INTERMOUNTAIN WEST ON TUESDAY. CURRENT GUIDANCE KEEPS US FAR
ENOUGH AWAY FROM THE WAVE TO LIMIT CONVECTION TO THE FURTHEST
NORTHERN PORTIONS OF THE CWA, BUT THE PRESSURE GRADIENT WILL
INCREASE SOUTHWESTERLY WINDS ON TUESDAY.
HIGH PRESSURE STARTS TO BUILD INTO THE FOUR CORNERS BY MIDWEEK
NEXT WEEK WITH A 598DM RIDGE CENTERED OVER THE WEST BY THE END OF
NEXT WEEK. THE POSITIONING OF THIS IS STILL A BIT UNCERTAIN WITH
SOME GUIDANCE HAVE THIS CENTERED OVER EASTERN NEVADA AND OTHERS
HAVING IT OVER THE FOUR CORNERS. THE PLACEMENT OF THIS AXIS WILL
DICTATE HOW MUCH MOISTURE WE CAN ADVECT BACK INTO THE AREA. BUT
THIS RIDGE WILL BRING A RETURN TO ABOVE NORMAL TEMPERATURES.
AVIATION
SLC...SOUTHERLY WINDS WILL SHIFT TO THE NORTHWEST BETWEEN 20-21Z.
OTHERWISE, VFR CONDITIONS UNDER MUCH QUIETER SKIES IN STORE FOR
THE TERMINAL TODAY.
REST OF UTAH AND SOUTHWEST WYOMING...TERRAIN DRIVEN WINDS CAN BE
EXPECTED ACROSS THE AIRSPACE TODAY. ISOLATED SHOWERS OR EVEN A
THUNDERSTORM WILL BE POSSIBLE ACROSS NORTHEASTERN AND SOUTHWESTERN
UTAH. BRIEF REDUCTIONS IN VISIBILITY TO MVFR MAY OCCUR WITH THIS
CONVECTION.
FIRE WEATHER, ISSUED 200 AM MDT SAT AUG 15 2026
MUCH DRIER CONDITIONS WILL BUILD INTO THE REGION TODAY AS HIGH
PRESSURE SHIFTS EASTWARD. EXPECT HUMIDITIES TO DECREASE THROUGH
MIDWEEK ACROSS ALL LOCATIONS, REACHING CRITICAL LEVELS FOR THE
VALLEYS AS EARLY AS SUNDAY. A SYSTEM MOVING ACROSS THE NORTHERN
INTERMOUNTAIN REGION WILL BRING AN INCREASED THREAT OF GUSTY
WINDS...WITH ELEVATED TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS
TUESDAY AND WEDNESDAY ACROSS CENTRAL AND SOUTHERN UTAH.
OUTSIDE OF ISOLATED THUNDERSTORMS ACROSS MAINLY THE HIGHER
TERRAIN, THERE IS LITTLE THREAT OF WETTING RAINS OVER THE NEXT
SEVEN DAYS.
SLC WATCHES/WARNINGS/ADVISORIES
UT...NONE.
WY...NONE.
