NATIONAL WEATHER SERVICE BOISE ID
912 PM MDT SUN JUL 19 2026
HIGH TEMPERATURES CONSISTENTLY REACHING 100 DEGREES OR MORE WILL IMPACT
SOUTHERN IDAHO EARLY THIS WEEK. HEAT ADVISORIES ARE IN EFFECT FOR MUCH OF THE
HIGH DESERT AND SNAKE PLAIN MONDAY AFTERNOON. HAZY SKIES AND PATCHY SMOKE WILL
PERSIST ACROSS SW, CENTRAL, AND THE PANHANDLE REGION OF IDAHO. TEMPERATURES
COOL A FEW DEGREES IN THE MIDWEEK, BUT STILL REMAIN HOT, AS MONSOONAL MOISTURE
ARRIVES. THIS WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS, ESPECIALLY OVER
HIGHER TERRAIN, TO THE STATE EACH AFTERNOON TUESDAY THROUGH THURSDAY. STORMS
WILL PRODUCE GUSTY WINDS, SMALL HAIL, AND HEAVY RAIN. HEAVY RAIN POSES A FLASH
FLOODING RISK PRIMARILY OVER STEEP TERRAIN AND BURN SCARS. LATE THIS WEEK AND
THE COMING WEEKEND, HOT, DRY, AND WINDY CONDITIONS MOVE BACK IN.
