NATIONAL WEATHER SERVICE BOISE ID
850 PM 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 TONIGHT INTO 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
NEAR 3000-4000 FEET BEFORE RISING TO 5000-6000 FEET 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.
