AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1136 AM MDT MON JUN 30 2025
VFR CONDITIONS CONTINUE WITH GENERALLY LIGHT WINDS TODAY. A WEAK
FEATURE ROTATING NORTH INTO EAST IDAHO MAY BE JUST ENOUGH TO PRODUCE
A FEW HIGH-BASED THUNDERSTORMS ALONG THE UT BORDER. A FEW OF THE
HIGH-RES MODEL SOLUTIONS GENERATE CONVECTIVE ACTIVITY POTENTIALLY
IMPACTING BYI LATE THIS AFTERNOON AND EARLY EVENING. CONFIDENCE IS
LOW, BUT JUST HIGH ENOUGH TO ADD A VCTS FOR 22Z-02Z. BETTER CHANCES
EXIST FOR TOMORROW AFTERNOON/EVENING AFTER 18Z, SO POTENTIAL
INCLUSION FOR MORE SITES IN THE 00Z ISSUANCE TODAY.
FIRE WEATHER
ISSUED AT 146 PM MDT MON JUN 30 2025
VERY WARM TEMPERATURES CONTINUE. REMNANTS OF A SOUTHWEST MONSOONAL
SURGE SHIFT NORTH INTO EAST IDAHO THIS WEEK. THERE MAY BE ENOUGH FOR
A VERY ISOLATED DRY THUNDERSTORM OR TWO ACROSS THE SOUTHERN SAWTOOTH
EARLY THIS EVENING, BUT CONFIDENCE IS LOW. BETTER MOISTURE PUSHES
NORTH ACROSS ALL EAST IDAHO FIRE DISTRICTS FOR TUESDAY THROUGH THE
REST OF THE WEEK. MOST THUNDERSTORMS WILL BE DRY THOUGH A FEW STORMS
WILL HAVE THE CAPABILITY OF PRODUCING GREATER PRECIPITATION AMOUNTS,
ESPECIALLY AS THE WEEK PROGRESSES. AFTERNOON HUMIDITIES TODAY AND
TUESDAY WILL GENERALLY BE IN THE TEENS, RECOVERING SLIGHTLY ABOVE
CRITICAL THRESHOLDS FOR THE REMAINDER OF THE WEEK WITH THE MOISTURE
SURGE. WINDS ARE EXPECTED TO REMAIN BELOW CRITICAL THRESHOLDS.
PIH WATCHES/WARNINGS/ADVISORIES
