IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
508 AM MST WED JAN 28 2026
A WEAK COLD FRONT MOVING ACROSS THE STATE TODAY WILL BRING LIGHT MOUNTAIN SNOW
AND A WINTRY MIX TO THE VALLEYS. HIGH PRESSURE REBUILDS QUICKLY BEHIND THIS
SYSTEM, LEADING TO DRY CONDITIONS FOR CENTRAL AND SOUTHERN IDAHO THROUGH THE
UPCOMING WEEKEND. STRONG TEMPERATURE INVERSIONS WILL LIKELY REDEVELOP IN
SOUTHERN AND CENTRAL VALLEYS, RESULTING IN PERSISTENT LOW CLOUDS, PATCHY
MORNING FOG, AND POTENTIAL AIR QUALITY DEGRADATION. THE IDAHO PANHANDLE WILL
REMAIN ON THE PERIPHERY OF A MORE ACTIVE PATTERN, KEEPING CHANCES FOR LIGHT
SNOW IN THE FORECAST THROUGH SATURDAY. TEMPERATURES STATEWIDE WILL REMAIN NEAR
OR SLIGHTLY ABOVE SEASONAL AVERAGES, EXCEPT IN VALLEY LOCATIONS WHERE STUBBORN
CLOUD COVER MAY KEEP DAYTIME HIGHS COOLER. WINDS ARE EXPECTED TO REMAIN LIGHT
ACROSS THE MAJORITY OF THE STATE OUTSIDE OF THE IMMEDIATE FRONTAL PASSAGE.
LOOKING INTO NEXT WEEK, A MORE SUBSTANTIAL WEATHER SYSTEM MAY APPROACH FROM THE
WEST, POTENTIALLY INCREASING PRECIPITATION CHANCES BY MONDAY.
