FIRE WEATHER
ISSUED AT 128 PM MDT THU JUL 3 2025
EARLY REGION OF SHOWERS HAS SHIFTED INTO WYOMING, ALLOWING FOR
CLEARING SKIES AND THE DEVELOPMENT OF NEW SHOWERS AND THUNDERSTORMS.
EARLY AFTERNOON RADAR SHOWS CURRENT DEVELOPMENT OVER THE CENTRAL
MOUNTAINS, WITH NEW DEVELOPMENT EXPECTED ACROSS THE SOUTHERN
SAWTOOTHS AND CARIBOU NF THIS AFTERNOON. GUSTS 25-45 MPH WILL BE
POSSIBLE. ALTHOUGH THE THUNDERSTORM ACTIVITY IS EXPECTED TO DECREASE
AFTER SUNSET, THE SHOWERS MAY LINGER OVERNIGHT. A SECOND BROAD AREA
OF SHOWERS WILL DEVELOP LATE TONIGHT INTO EARLY FRIDAY MORNING,
SHIFTING NORTHEAST ACROSS THE REGION. WETTING RAINS WILL BE POSSIBLE
WITH THIS FEATURE, MAINLY OVER HIGHER ELEVATION ZONES. BEHIND THE
MAIN BAND, AFTERNOON HEATING WILL ALLOW A FEW THUNDERSTORMS TO
DEVELOP. OVERALL CHANCES FOR WETTING RAINS DURING THE DAY FRIDAY
EXCEED 40% FOR ALL BUT THE MIDDLE SNAKE REGION. MOST OF THE NORTHERN
SAWTOOTH, SALMON-CHALLIS, AND TARGHEE NFS HAVE A 60% OR HIGHER
CHANCE OF WETTING RAINS. LOCALIZED RAINFALL AMOUNTS COULD APPROACH
OR EXCEED ONE-QUARTER INCH ESPECIALLY WITH HEAVIER
SHOWER/THUNDERSTORM OCCURRENCE. COOLER TEMPERATURES AND HIGHER
DAYTIME HUMIDITIES REMAIN FORECAST, AND THE COMBINATION OF THE ABOVE
FACTORS WILL PRECLUDE ANY FIRE-RELATED HEADLINE FOR THE DAY.
ONCE AGAIN, THUNDERSTORM ACTIVITY IS EXPECTED TO DIMINISH AROUND
SUNSET, THOUGH A FEW SHOWERS COULD LINGER JUST BEYOND MIDNIGHT. A
FEW SHOWERS REMAIN POSSIBLE FOR SATURDAY AFTERNOON/EVENING,
OTHERWISE HIGH PRESSURE REBOUNDS ACROSS THE INTERMOUNTAIN WEST.
EXPECT A DRYING AND WARMING TREND TO LAST THROUGH MID-WEEK NEXT
WEEK.
