IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
927 AM MDT SAT MAR 21 2026
A COLD FRONT WILL SWEEP ACROSS THE STATE TODAY, BRINGING A RETURN OF MOUNTAIN
PRECIPITATION AND LOWERING TEMPERATURES CLOSER TO SEASONAL NORMALS BY SUNDAY.
WHILE SOUTHERN VALLEYS WILL REMAIN MOSTLY DRY, THE CENTRAL MOUNTAINS AND
EASTERN HIGHLANDS MAY SEE LIGHT RAIN AND SNOW SHOWERS WITH THE FRONTAL PASSAGE.
BREEZY TO GUSTY CONDITIONS WILL ACCOMPANY THE FRONT, PARTICULARLY ACROSS THE
SNAKE RIVER PLAIN AND THE HIGH DESERT OF SOUTHERN IDAHO. HIGH PRESSURE BUILDS
IN BRIEFLY FOR THE START OF THE WORK WEEK, RESULTING IN A SHORT PERIOD OF DRY
AND STABLE CONDITIONS STATEWIDE. ANOTHER WEATHER SYSTEM IS ANTICIPATED BY THE
MIDDLE OF NEXT WEEK, POTENTIALLY BRINGING MORE WIDESPREAD MOISTURE AND GUSTY
WINDS TO THE IDAHO PANHANDLE AND NORTH-CENTRAL IDAHO. SNOW LEVELS WILL
FLUCTUATE WITH THESE PASSING SYSTEMS, GENERALLY REMAINING HIGHER IN THE SOUTH
AND LOWER ACROSS NORTHERN IDAHO. EMERGENCY PLANNERS SHOULD MONITOR FOR
LOCALIZED PONDING ON ROADS IN NORTHERN AREAS WHERE HEAVIER RAIN OCCURS LATER IN
THE WEEK.
