DISCUSSION
ISSUED AT 915 PM MDT WED MAY 20 2026
WE CONTINUE TO BE SITUATED UNDER AN UPPER LEVEL TROUGH THAT WILL
SLOWLY BEGIN TO TRACK EASTWARD BY THE END OF THE WEEK, GIVING WAY TO
A RIDGE OF HIGH PRESSURE. IN THE MEANTIME, TEMPERATURES WILL HOVER
AT OR BELOW NORMAL FOR THE NEXT FEW DAYS, BEFORE WARMING TO ABOVE
NORMAL BY SUNDAY. IN TERMS OF PRECIPITATION, THURSDAY AFTERNOON WILL
SEE THE BEST CHANCE (50-70%) FOR SCATTERED SHOWERS WITH SOME
THUNDERSTORMS POSSIBLE ACROSS THE NORTHERN PART OF OUR CWA.
ALTHOUGH, ACCUMULATIONS APPEAR TO BE QUITE MINIMAL. AS THE SHORTWAVE
TROUGH AND ASSOCIATED COLD FRONT PUSH THROUGH THE AREA INTO THURSDAY
EVENING, PRECIPITATION CHANCES HAVE THE ABILITY TO SPREAD FURTHER
SOUTH ALONG THE I-70 CORRIDOR AND CENTRAL MOUNTAINS. ADDITIONALLY,
AS A RESULT OF THIS SYSTEM MOVING THROUGH, GUSTY WINDS WILL BE
PRESENT. GUSTS WILL GENERALLY FALL WITHIN THE 25-30 MPH RANGE, WITH
LOCALLY HIGHER GUSTS POSSIBLE. CRITICAL FIRE WEATHER CONDITIONS WILL
EXIST FOR TOMORROW AFTERNOON, REFER TO THE FIRE WEATHER SECTION FOR
MORE ON THAT. FRIDAY WILL BE MOSTLY DRY FOLLOWING THE FRONTAL
PASSAGE WITH A CHANCE (30%) FOR LIGHT SHOWERS IN THE NORTHERN
MOUNTAINS DUE TO LINGERING MOISTURE.
THE WEEKEND AND BEYOND:
AS WE MOVE INTO MEMORIAL DAY WEEKEND, CONDITIONS APPEAR TO BE QUITE
PLEASANT AS THE AFOREMENTIONED RIDGE OF HIGH PRESSURE BEGINS TO
SITUATE ITSELF OVER THE INTERMOUNTAIN WEST. AS PREVIOUSLY MENTIONED,
TEMPERATURES WILL BE ABOUT 5-10 DEGREES ABOVE NORMAL WITH THIS
RIDGE. DUE TO SOME LINGERING ENERGY AND AVAILABLE MOISTURE,
AFTERNOON CONVECTION COULD BE SUPPORTED EACH DAY THROUGH THE
WEEKEND, FAVORING THE HIGHER TERRAIN. BEYOND SUNDAY, ANOTHER LOW
PRESSURE SYSTEM WILL ESTABLISH ITSELF OVER THE PACIFIC NORTHWEST
GIVING WAY TO INCREASED PRECIPITATION CHANCES FOR OUR AREA MONDAY
INTO TUESDAY.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 546 PM MDT WED MAY 20 2026
GUSTY WINDS WILL START DYING DOWN OVER THE NEXT FEW HOURS AND
BECOME GENERALLY LIGHT OVERNIGHT. HIGH LEVEL CLOUDS WILL DRIFT
OVERHEAD TONIGHT AS VFR REMAINS THE PREDOMINANT FLIGHT CATEGORY.
AN APPROACHING SYSTEM FROM THE NORTH WILL BRING INCREASING
CLOUDS TOMORROW AND INCREASING CHANCES FOR RAINSHOWERS AND A FEW
STORMS. KVEL AND KHDN WILL HAVE INCREASING CHANCES AFTER 18Z
FOR THIS PRECIP. KRIL, KASE AND KEGE SEE THEIR CHANCES INCREASE
TOWARDS THE END OF THE TAF PERIOD. OUTSIDE OF THE PRECIP, SOME
GUSTY SOUTHWESTERLY WINDS OF 25 TO 30KTS ARE ALSO EXPECTED IN
THE AFTERNOON.
FIRE WEATHER
ISSUED AT 915 PM MDT WED MAY 20 2026
A FRONTAL PASSAGE ASSOCIATED WITH A SHORTWAVE TROUGH WILL TRAVERSE
THE AREA THURSDAY. THIS WILL CAUSE WINDS TO INCREASE THROUGHOUT THE
AREA THURSDAY AFTERNOON LEADING TO WIDESPREAD CRITICAL FIRE WEATHER
CONDITIONS FOR EAST-CENTRAL UTAH AND WEST-SOUTHWEST COLORADO. RED
FLAG WARNINGS HAVE BEEN ISSUED FOR THESE AREAS (UT ZONE 490 AND CO
ZONE 290) FROM 1PM-7PM THURSDAY. LOCALIZED CRITICAL FIRE WEATHER
CONDITIONS ARE POSSIBLE ELSEWHERE, BUT CONDITIONS WILL NOT MEET RED
FLAG CRITERIA.
