KSLC, ISSUED 1044 PM MDT SUN AUG 9 2026...
THE SLC TERMINAL WILL SEE PRIMARILY VFR
CONDITIONS THROUGH MONDAY. SOUTHERLY WINDS ARE LIKELY TO PERSIST
THROUGH THE NIGHT AND INTO MONDAY MORNING, WITH NORTHWESTERLY
WINDS EXPECTED TO DEVELOP AROUND 19-20Z. HOWEVER, THERE IS A 40%
CHANCE OF THUNDERSTORMS OVER/NEAR THE TERMINAL BETWEEN 19-23Z
WHICH COULD RESULT IN GUSTY AND ERRATIC WINDS. SOUTHERLY DRAINAGE
WINDS MAY DEVELOP EARLIER THAN NORMAL ON MONDAY EVENING AHEAD
ANOTHER POTENTIAL ROUND OF SHOWERS AND THUNDERSTORMS DEVELOPING
BETWEEN 01- 04Z.
REST OF UTAH AND SOUTHWEST WYOMING...GENERALLY VFR CONDITIONS
WILL PREVAIL ACROSS THE AIRSPACE TONIGHT THROUGH MONDAY. SCATTERED
SHOWERS AND THUNDERSTORMS WILL REDEVELOP MONDAY AFTERNOON.
POCKETS OF HEAVY RAIN AND GUSTY WINDS MAY BRING BRIEF MVFR
CONDITIONS AND CEILINGS THAT COULD RESULT IN TEMPORARY MOUNTAIN
OBSCURATIONS. GUSTY AND ERRATIC OUTFLOW WINDS CAN BE EXPECTED NEAR
SHOWERS AND THUNDERSTORMS. 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
HIGH PRESSURE WILL REMAIN PARKED OVER THE FOUR
CORNERS REGION THROUGH WEDNESDAY. THE RESULTANT SOUTHERLY FLOW
OVER UTAH WILL CONTINUE TO DRAW DEEP MONSOON MOISTURE NORTHWARD.
THIS WILL RESULT IN SHOWERS AND THUNDERSTORMS DEVELOPING EACH
AFTERNOON, FOCUSED PRIMARILY OVER THE HIGHER TERRAIN, WITH THE
STORMS BECOMING WETTER AS THE MOISTURE CONTINUES TO MOVE INTO THE
LOWER LEVELS. THIS PATTERN WILL BRING IMPROVEMENT IN RELATIVE
HUMIDITY VALUES AND AN INCREASING CHANCE OF WETTING RAINFALL,
THOUGH ANY STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING GUSTY
AND ERRATIC THUNDERSTORM WINDS AS WELL AS LIGHTNING. THE RIDGE IS
EXPECTED TO MOVE EAST FOR THE LATTER HALF OF THE WEEK, THOUGH A
RELATIVELY MOIST AND UNSTABLE PATTERN IS EXPECTED TO REMAIN OVER
THE AREA FOR AT LEAST MUCH OF THE REMAINDER OF THE WEEK.
