DISCUSSION
ISSUED AT 104 AM MDT SAT JUL 4 2026
TODAY THROUGH MON NIGHT...HIGH PRESSURE HAS BUILT INTO EASTERN
IDAHO FOR TODAY, AND THIS WILL MEAN WARMER AIR AND LIGHT WIND.
AFTERNOON TEMPERATURES PEAK IN THE LOWER 90S FOR THE EASTERN
MAGIC VALLEY AND WESTERN HALF OF THE SNAKE RIVER PLAIN.
CONTINUED RIDGE BUILDING PUSHES TEMPERATURES IN THE LOWER
ELEVATIONS INTO THELOWER TO MIDDLE 90S. CLOUD COVER ON MON MEANS
INCREASED RISK OF SHOWERS AND THUNDERSTORMS ALONG WITH
TEMPERATURES DOWN 3 TO 7 DEG F.
WIND STAYS LIGHT FOR TODAY AND SUN, THEN A SOUTHWEST FLOW IN THE
AFTERNOON RISES TO 10KT TO 15KT, STAYING BELOW LAKE WIND
ADVISORY CONDITIONS.
TUE THROUGH FRI...TUE HAS ENOUGH OF A SOUTHERLY COMPONENT ALOFT
THAT THE DOOR IS OPEN FOR SOME REMNANTS OF THE SOUTHWEST
MONSOON, AS IT WILL BE ON MON, BUT SUBSEQUENT DAYS THE FLOW
BECOMES MORE WESTERLY AND DRIER. CLUSTERS ARE ONLY DIFFERENT IN
THE 500MB HEIGHTS AND THUS JUST HOW HOT IT WILL GET IS THE MAIN
DIFFERENCE. MOST NBM POPS IN THIS PERIOD ARE SUB-10 PERCENT
AFTER TUE. TEMPERATURES STAY 7 TO 12 DEG F ABOVE NORMAL FOR
HIGHS, OVERNIGHT LOWS NEAR NORMAL FOR THE TIME OF YEAR.
AVIATION /12Z TAFS THROUGH 12Z SUNDAY/
ISSUED AT 424 AM MDT SAT JUL 4 2026
HIGH PRESSURE DOMINATING MEANS AT MOST SKC-SCT IN THE MID-LEVELS
OR HIGHER, SO NO CIG ISSUES. NO PRECIPITATION OR DUST EXPECTED,
SO NO VSBY ISSUES. SO ONLY WIND SHIFTS MAKE UP THE FM GROUPS.
WIND SHOULD NOT GET TO MORE THAN 15KT ANYWHERE, MOSTLY DRIVEN,
WHEN IT HAS A DIRECTION, BY THE SLOPE-VALLEY WIND EFFECT.
FIRE WEATHER
ISSUED AT 104 AM MDT SAT JUL 4 2026
WIDESPREAD HUMIDITY EVERYWHERE EXCEPT IN THE CENTRAL IDAHO
MOUNTAINS AND THE UPPER SNAKE RIVER HIGHLANDS WILL DRY OUT TO
BELOW CRITICAL THRESHOLDS OVER THE NEXT THREE DAYS, SAT-SUN-MON.
A SURGE OF HUMIDITY ARRIVES TOWARDS THE END OF MON AND INTO TUE
TO BRING HUMIDITY UP SLIGHTLY AS TEMPERATURES ALSO STAY VERY
WARM FOR THE TIME OF YEAR. HOWEVER, DRYING RETURNS ON TUE AS THE
UPPER LEVEL WIND SHIFTS TO A DRY WESTERLY AIRFLOW. WIND IS
EXPECTED TO BE BELOW CRITICAL THRESHOLDS UNTIL MAYBE THU.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
