SHORT TERM /THROUGH SUNDAY NIGHT/
ISSUED AT 122 AM MDT SAT MAY 31 2025
SHALLOW UPPER LEVEL RIDGE SLIDES EAST TODAY AND WEAK WESTERLY
FLOW ALOFT WILL MOVE INTO REGION. IT WILL BE VERY WARM TODAY
WITH VALLEY HIGHS IN THE MID 80S TO LOWER 90S. MOUNTAIN HIGHS IN
THE 70S TO LOWER 80S. NOT EXPECTING ANY PRECIPITATION TODAY.
LOWS TONIGHT IN THE 50S VALLEYS AND 40S MOUNTAINS. IT WILL BE
WARM AGAIN SUNDAY WITH HIGHS IN THE 70S MOUNTAINS AND 80S
VALLEYS. AN UPPER LEVEL TROF MOVES ON SHORE FROM THE PACIFIC
SUNDAY AND SOUTHWESTERLY FLOW COMBINED WITH INSTABILITY WILL
BRING SHOWERS AND THUNDERSTORMS BACK INTO THE FORECAST GRIDS
SUNDAY AFTERNOON AND SUNDAY NIGHT WITH THE BEST CHANCES IN THE
CENTRAL MOUNTAINS AND EASTERN MOUNTAINS. EXPECT AN INCREASE IN
WINDS WITH THE SYSTEM SUNDAY AS WELL WITH WIDESPREAD 10 TO 20
MPH SUSTAINED WINDS IN THE MAGIC VALLEY AND SNAKE RIVER PLAIN
INTO THE CENTRAL MOUNTAINS.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 122 AM MDT SAT MAY 31 2025
NEXT WEEK CONTINUES TO LOOK COOLER (KICKING OFF WITHIN 5 DEGREES OF
CLIMATOLOGICAL NORMALS FOR EARLY JUNE THROUGH WEDNESDAY, THEN SLOWLY
TRENDING WARMER WITH SOME 80S RETURNING FOR HIGH TEMPERATURES AT
LOWER ELEVATIONS THURSDAY ONWARD), AS WELL AS LESS IMPACTFUL IN
TERMS OF WIND AND PRECIPITATION. THE ENTIRE WEEK WILL BE DOMINATED
BY BROAD/LONGWAVE TROUGHING WITH A FEW EMBEDDED SHORTWAVE TROUGHS
PUSHING THROUGH, BUT THESE WILL LARGELY JUST SUPPORT CHANCES OF
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS FOCUSED IN SOME OF
OUR MOUNTAINS AND ALONG THE WYOMING BORDER CORRIDOR. REGIONALLY THE
BEST CHANCE OF MORE WIDESPREAD SHOWERS AND THUNDERSTORMS WILL BE
TUESDAY AFTERNOON, ESPECIALLY ACROSS THE CENTRAL MOUNTAINS, EASTERN
HIGHLANDS, AND UPPER SNAKE PLAIN. OTHERWISE, MONDAY LOOKS A BIT
BREEZY IN THE EASTERN MAGIC VALLEY INTO THE RAFT RIVER REGION, AND
OVERALL QPF AMOUNTS THROUGHOUT THE WEEK APPEAR LIGHT.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1012 PM MDT FRI MAY 30 2025
RIDGE OF HIGH PRESSURE CONTINUES TO INTENSIFY OVER THE REGION
WHICH WILL RESULT IN MAINLY CLEAR SKIES, LIGHT WINDS AND HOT
TEMPERATURES. NOT EXPECTING ANY PRECIPITATION THROUGH THE
PERIOD. LIGHT, VARIABLE WINDS OVERNIGHT INCREASE TO CLOSER TO 10
KTS DURING THE AFTERNOON SATURDAY BUT THAT'LL BE ABOUT THE MOST
IMPACTFUL THING TO AVIATION OVER THE NEXT FEW DAYS, WHICH ISN'T
MUCH. THAT BEING SAID, VFR EXPECTED TO PREVAIL.
