IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
906 AM MDT FRI APR 24 2026
AN UNSEASONABLY COLD AND UNSETTLED WEATHER PATTERN WILL PERSIST ACROSS THE
STATE THROUGH EARLY NEXT WEEK AS A BROAD TROUGH REMAINS ANCHORED OVER THE
REGION. HIGH PRESSURE BUILDING TO THE WEST WILL KEEP THE IDAHO PANHANDLE MOSTLY
DRY THROUGH THE WEEKEND, THOUGH ISOLATED AFTERNOON SHOWERS REMAIN POSSIBLE IN
THE NORTHERN MOUNTAINS. CONVERSELY, EASTERN IDAHO WILL EXPERIENCE SIGNIFICANT
IMPACTS THROUGH FRIDAY MORNING, WITH ADDITIONAL SNOW ACCUMULATIONS OF 2 TO 4
INCHES POSSIBLE ON MOUNTAIN PASSES AND LINGERING GUSTY WINDS. THE PRIMARY
CONCERN FOR SOUTHERN AND CENTRAL IDAHO OVER THE NEXT SEVERAL DAYS WILL BE A
WIDESPREAD HARD FREEZE, WITH TEMPERATURES DROPPING WELL BELOW FREEZING AND
THREATENING SENSITIVE VEGETATION. WHILE A BRIEF PERIOD OF LIGHTER WINDS AND
CLEARING SKIES IS EXPECTED SATURDAY, ANOTHER WEATHER SYSTEM WILL MOVE SOUTH
FROM CANADA EARLY NEXT WEEK, BRINGING A RENEWED CHANCE FOR SCATTERED SHOWERS
AND BREEZY CONDITIONS STATEWIDE. TEMPERATURES WILL REMAIN 5 TO 10 DEGREES BELOW
SEASONAL AVERAGES BEFORE A MORE PRONOUNCED WARMING TREND BEGINS TOWARD THE
MIDDLE OF NEXT WEEK. LOCALIZED FLOODING AND ROCK SLIDES REMAIN A MINOR CONCERN
IN STEEP DRAINAGES WHERE RECENT HEAVY RAINFALL AND FLUCTUATING SNOW LEVELS HAVE
SATURATED SOILS.
