KEY MESSAGES
- SHOWERS WILL RETURN AND GRADUALLY INCREASE THROUGH TUESDAY
- COLDER TEMPERATURES WILL COME BACK WITH BETTER CHANCE OF RAIN
AND SNOW MIDWEEK
SHORT TERM /THROUGH TUESDAY NIGHT/
ISSUED AT 106 PM MDT MON OCT 13 2025
A FEW SHOWERS ARE EXPECTED THIS EVENING ACROSS THE CENTRAL
MOUNTAINS BEFORE WE SEE A RAPID INCREASE IN DEVELOPMENT
OVERNIGHT. MULTIPLE BANDS OF SHOWERS WITH A FEW THUNDERSTORMS
ARE LIKELY TUESDAY INTO TUESDAY NIGHT. AT THAT POINT, WE MAY SEE
SOME ENHANCEMENT FROM THE WOOD RIVER VALLEY UP THROUGH ISLAND
PARK DUE TO DECENT SOUTH TO SOUTHEAST FLOW ACROSS OUR PART OF
THE STATE. ANY ACCUMULATING SNOW SHOULD REMAIN ABOVE 7000FT,
ALTHOUGH WE MAY NEED TO WATCH WHERE COLDER AIR STAYS IN VALLEY
LOCATIONS TO SEE IF WE END UP WITH AT LEAST RAIN MIXING WITH
SNOW...EVEN IF NO ACCUMULATION TAKES PLACE. RIGHT NOW, THIS
PATTERN ISN'T CONDUCIVE TO SEEING ANY SURPRISE POCKETS OF
FREEZING RAIN WHERE IT STAYS COLDER OVERNIGHT. HIGHS TUESDAY
SHOULD REMAIN IN THE MID 50S TO MID 60S IN THOSE LOWER VALLEYS.
WE COULD SEE IF EEK OUT INTO THE UPPER 60S FOR AREAS FAVORED
WITH SOUTHERLY DOWNSLOPE CONDITIONS.
LONG TERM /WEDNESDAY THROUGH MONDAY/
ISSUED AT 106 PM MDT MON OCT 13 2025
WEDNESDAY BEGINS WITH A CLOSED UPPER LOW IN PLACE ACROSS CENTRAL
NEVADA WITH BROAD UPPER TROUGHING IN PLACE ACROSS EASTERN IDAHO.
THIS WILL SET THE STAGE FOR A FEW UNSETTLED DAYS ON WEDNESDAY AND
THURSDAY WITH WIDESPREAD PRECIPITATION EXPECTED THROUGHOUT THE AREA
ON WEDNESDAY. TEMPERATURES WILL BE WELL BELOW NORMAL, BY 10 TO 15
DEGREES, THROUGHOUT EASTERN IDAHO WITH HIGHS ONLY IN THE 40S TO
LOWER 50S. SNOW LEVELS WILL BE RUNNING AROUND 7000-7500 FEET DURING
THIS PERIOD SO EXPECT SOME ACCUMULATIONS ACROSS THE HIGHER TERRAIN
OF THE CENTRAL MOUNTAINS AND EASTERN HIGHLANDS WHERE SOME WINTER
WEATHER ADVISORIES MAY BE NEEDED ABOVE THE AFOREMENTIONED ELEVATIONS
FOR ACCUMULATIONS. STAY TUNED. THURSDAY LOOKS LIKE THE COLDEST DAY
WITH THE LOW NEARLY CENTERED NEAR THE BEAR LAKE REGION WITH AREAS
NEAR THE WYOMING BORDER PERHAPS STAYING IN THE 30S TO LOWER 40S FOR
HIGHS, WITH 40S AND LOW 50S ELSEWHERE. PRECIP WILL SLOWLY TAPER OFF
FROM WEST TO EAST THROUGHOUT THE DAY AS THE LOW STARTS TO MOVE EAST
OF THE AREA OVER THE COURSE OF THE DAY.
RIDGING LOOKS TO QUICKLY BUILD OVER THE AREA ON FRIDAY AND
CONTINUING INTO THE WEEKEND WHICH SHOULD ALLOW TEMPS TO WARM UP A
FEW DEGREES EACH DAY RETURNING CLOSER TO SEASONAL NORMS BY SUNDAY.
PRECIP CHANCES LOOK LIMITED TO THE HIGHER TERRAIN DURING THIS PERIOD
ALTHOUGH ANOTHER DEEP UPPER TROUGH APPEARS POISED TO APPROACH THE
REGION ON MONDAY. AS SUCH, EXPECT CLOUDS TO BE ON THE INCREASE
DURING THE AFTERNOON HOURS SUNDAY AND INTO THE OVERNIGHT HOURS
MONDAY MORNING AS ANOTHER SYSTEM LOOKS TO BRING MUCH COOLER
TEMPERATURES ALONG WITH RAIN/SNOW CHANCES FOR THE EARLY PART OF NEXT
WEEK.
