BROAD UPPER LEVEL TROF WILL SLIDE OVER IDAHO TODAY AND WILL

AND SOUTHERN MOUNTAINS WHERE AN ADDITIONAL 1 TO 4 INCHES OF SNOW
MAY FALL THROUGH TONIGHT. BEAR RIVER RANGE COULD SEE LOCALLY
HIGHER AMOUNTS. WINTER WEATHER ADVISORIES REMAIN IN EFFECT
THROUGH THIS AFTERNOON AND AFTERNOON CONVECTIVE ACTIVITY WILL
LIKELY SEE SOME ENHANCED ACTIVITY. THERE WILL BE AT LEAST A
CHANCE OUTSIDE OF THE EASTERN AND SOUTHERN MOUNTAINS FOR RAIN
AND SNOW SHOWERS ESPECIALLY THIS AFTERNOON BUT SIGNIFICANT
ACCUMULATIONS NOT EXPECTED. MAIN UPPER TROF MOVES EAST WEDNESDAY
BUT COLD AIR ALOFT REMAINS AND ENOUGH INSTABILITY FOR CONTINUED
RAIN AND SNOW SHOWERS AGAIN MAINLY WEDNESDAY AFTERNOON. IT WILL
BE VERY COLD WITH HIGHS TODAY IN THE 30S MOUNTAINS AND 40S LOW
ELEVATIONS AND LOWS TONIGHT SINGLE DIGITS AND TEENS MOUNTAINS
AND 20S LOW ELEVATIONS. HIGHS WEDNESDAY AGAIN IN THE 30S AND
40S WITH LOWS WEDNESDAY NIGHT TEENS AND 20S ONCE AGAIN. SO VERY

GK
LONG TERM /THURSDAY THROUGH MONDAY/
ISSUED AT 248 AM MDT TUE APR 1 2025
LARGE UPPER TROUGH OVER THE REGION WILL CONTINUE TO PRODUCE COOL AND
UNSETTLED WEATHER THURSDAY INTO FRIDAY. MOST OF THE PRECIPITATION AT
THIS POINT LOOKS RELATIVELY LIGHT. THEN A RIDGE WILL BUILD INTO THE
AREA. THIS SHOULD PRODUCE MOSTLY DRY WEATHER WITH ABOVE NORMAL
TEMPERATURE FOR SUNDAY AND BEYOND. THE ONLY POTENTIAL HICCUP IS THAT
SOME OF THE MODEL SOLUTIONS ARE SHOWING A WEAK SHORTWAVE TROUGH
PASSING THROUGH ON MONDAY WHICH COULD PRODUCE A FEW SHOWERS. AT THIS
POINT THOUGH, THIS SOLUTION IS IN THE MINORITY.
AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
ISSUED AT 408 AM MDT TUE APR 1 2025
MODELS HINTING AT AN MVFR DECK DEVELOPING ACROSS THE
LOWER SNAKE PLAIN AND EASTERN MAGIC VALLEY FOR A TIME THIS MORNING.
HANDLING THIS WITH TEMPO GROUPS AS THERE STILL IS UNCERTAINTY IF
THIS WILL DEVELOP AND JUST HOW LOW IT WOULD BE. OTHERWISE SOME
MORNING SHOWERS NEAR THE SUN/BYI AREA SHOULD DISSIPATE IN A FEW
HOURS. THEN WE EXPECT REDEVELOPMENT OF SNOW SHOWERS IN MOST
LOCATIONS THIS AFTERNOON. IDA/PIH/DIJ HAVE THE BEST CHANCES OF
SEEING RESTRICTIONS FROM SHOWERS THIS AFTERNOON. THINKING SHOWERS
AROUND SUN COULD HUG THE SURROUNDING TERRAIN. BRISK CONDITIONS
LIKELY TODAY AS WELL. SHOWERS AND WIND SHOULD WEAKEN THIS EVENING.
PIH WATCHES/WARNINGS/ADVISORIES
WINTER WEATHER ADVISORY UNTIL 6 PM MDT THIS EVENING FOR
IDZ058>060-063-064-066-067.
