IDAHO STATE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
907 AM MDT THU APR 30 2026
HIGH PRESSURE BUILDING OVER THE REGION WILL BRING A SIGNIFICANT WARMING TREND
AND DRY CONDITIONS TO MOST OF IDAHO THROUGH THE UPCOMING WEEKEND. AFTERNOON
HIGH TEMPERATURES ARE EXPECTED TO CLIMB 10 TO 15 DEGREES ABOVE SEASONAL
NORMALS, REACHING THE UPPER 70S AND LOW 80S IN LOWER ELEVATIONS BY SUNDAY.
WHILE DRY WEATHER WILL PREVAIL FOR THE MAJORITY OF THE STATE, ISOLATED
AFTERNOON SHOWERS AND THUNDERSTORMS REMAIN POSSIBLE THROUGH THIS EVENING ACROSS
THE CENTRAL MOUNTAINS AND THE HIGHER TERRAIN NEAR THE NEVADA BORDER. THESE
ISOLATED STORMS COULD PRODUCE LOCALIZED WIND GUSTS UP TO 30 MPH AND SMALL HAIL.
BREEZY CONDITIONS WILL ALSO PERSIST ACROSS EASTERN IDAHO TODAY, WITH GUSTS
NEAR 20 MPH BEFORE WINDS DIMINISH OVERNIGHT. THE WARM AND STABLE PATTERN WILL
LIKELY HOLD THROUGH MONDAY BEFORE A LOW PRESSURE SYSTEM APPROACHING FROM THE
SOUTH INTRODUCES A HIGHER CHANCE FOR WIDESPREAD RAIN AND THUNDERSTORMS BY THE
MIDDLE OF NEXT WEEK. EMERGENCY PLANNERS SHOULD MONITOR FOR A TRANSITION TO MORE
UNSETTLED WEATHER AND POTENTIAL LIGHTNING IMPACTS STARTING LATE SUNDAY
EVENING.
