IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
512 AM MDT MON MAR 9 2026
AN ACTIVE AND WINDY WEATHER PATTERN WILL IMPACT THE STATE THROUGH THE UPCOMING
WORK WEEK. A COLD FRONT CROSSING THE REGION TODAY AND TUESDAY WILL BRING
WIDESPREAD GUSTY WINDS AND A COOLING TREND, WITH THE STRONGEST GUSTS EXPECTED
ACROSS SOUTHEASTERN IDAHO. LIGHT TO MODERATE PRECIPITATION WILL BE FOCUSED
PRIMARILY ACROSS THE IDAHO PANHANDLE AND CENTRAL MOUNTAINS, WHERE COOLING
TEMPERATURES WILL ALLOW FOR ACCUMULATING MOUNTAIN SNOW. A POTENT ATMOSPHERIC
RIVER IS THEN FORECAST TO ARRIVE WEDNESDAY AND PERSIST THROUGH SATURDAY,
BRINGING MODERATE TO HEAVY PRECIPITATION TO THE NORTHERN AND CENTRAL PORTIONS
OF THE STATE. SOUTHERN IDAHO WILL REMAIN MOSTLY DRY DURING THIS PERIOD, THOUGH
WIDESPREAD BREEZY CONDITIONS WILL CONTINUE STATEWIDE. SNOW LEVELS WILL
FLUCTUATE SIGNIFICANTLY WITH THIS MID-WEEK SYSTEM, LIKELY STARTING LOW BEFORE
RISING AS WARMER AIR ARRIVES BY THE WEEKEND. HEAVY MOUNTAIN SNOW MAY IMPACT
TRAVEL OVER HIGH-ELEVATION PASSES, WHILE LOWER ELEVATIONS WILL SEE A TRANSITION
TO RAIN. ABOVE-NORMAL TEMPERATURES ARE EXPECTED TO RETURN TO ALL REGIONS BY
FRIDAY AND SATURDAY.
