IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
909 AM MDT WED APR 29 2026
UNSETTLED WEATHER CONTINUES THROUGH THE MIDDLE OF THE WEEK AS A BROAD TROUGH
REMAINS OVER THE REGION. CENTRAL AND EASTERN IDAHO CAN EXPECT DAILY CHANCES FOR
RAIN AND HIGH-ELEVATION SNOW SHOWERS, WITH ISOLATED AFTERNOON THUNDERSTORMS
POSSIBLE THROUGH WEDNESDAY. A SIGNIFICANT SHIFT IN THE WEATHER PATTERN BEGINS
ON THURSDAY AS A HIGH-PRESSURE RIDGE BUILDS OVER THE STATE. THIS WILL RESULT IN
A DRY AND SUBSTANTIAL WARMING TREND THROUGH THE END OF THE WEEK AND INTO NEXT
WEEKEND. HIGH TEMPERATURES ARE FORECAST TO RISE INTO THE 70S FOR MOST VALLEY
LOCATIONS, WITH SOME AREAS IN CENTRAL AND SOUTHERN IDAHO POTENTIALLY REACHING
THE LOW 80S BY SATURDAY. BREEZY CONDITIONS MAY PERSIST IN THE SNAKE RIVER PLAIN
DURING THIS TRANSITION, BUT NO SIGNIFICANT WIND IMPACTS ARE EXPECTED.
EMERGENCY PLANNERS SHOULD MONITOR THE RAPID WARMING LATE IN THE WEEK FOR
POTENTIAL INCREASES IN HIGH-ELEVATION SNOWMELT.
