TUE THROUGH THU NIGHT...A TROUGH IN THE PACIFIC NORTHWEST WILL
TRIGGER SHOWERS AND THUNDERSTORMS MAINLY THIS AFTERNOON AND
EVENING. BEST PRECIPITATION AMOUNTS SHOULD OCCUR IN THE CENTRAL
IDAHO MOUNTAINS, AND GENERALLY BETTER IN THE NORTH HALF OF THE
FORECAST AREA THAN IN THE SOUTH HALF. THE TROUGH IS SLOWLY
MOVING AND WILL MOVE INTO WESTERN IDAHO DURING THE DAY WED, AND
THROUGH EASTERN IDAHO WED NIGHT. THIS WILL MEAN A CONTINUED RISK
OF LIGHT PRECIPITATION AND THUNDERSTORMS. BY THU, THE TROUGH
HAS PASSED. CLEARER SKIES MEANS WARMING TO NEAR NORMAL WITH
DIMINISHING THREAT OF THUNDERSTORMS AND SHOWERS, MAINLY LIMITED
TO THE EASTERN HALF OF THE OF THE FORECAST AREA.
FRI THROUGH MON...THE RISK OF THUNDERSTORMS DIES OUT JUST IN
TIME FOR INDEPENDENCE DAY. TEMPERATURES WILL BE RIGHT AROUND
NORMAL, WHICH IS LOWER TO MIDDLE 80S IN THE SNAKE RIVER
PLAIN/EASTERN MAGIC VALLEY, 70S TO AROUND 80 FOR THE MOUNTAINS
AND HIGHLANDS. TEMPERATURES START TO SOAR SUN WITH SOME LOWER
ELEVATIONS SURPASSING 90 DEGREES. SHOWERS AND THUNDERSTORMS
DON'T RETURN UNTIL MON AFTERNOON.

ISSUED AT 1148 AM MDT TUE JUN 30 2026
WEAK IMPULSES MOVING THROUGH A REMNANT BROADER UPPER TROUGH OVER
THE REGION WILL COMBINE WITH ADEQUATE MOISTURE TO SUPPORT A
CHANCE OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EARLY
EVENING. WHILE AN ISOLATED SHOWER OR STORM CANNOT BE RULED OUT
AT ANY OF THE TERMINALS, THE BETTER POTENTIAL WILL EXIST AT KSUN
AND KDIJ. HAVE MAINTAINED A PROB30 THUNDERSTORM MENTION AT
THESE TERMINALS FROM ROUGHLY 19Z-01Z, WITH VCSH MENTIONED AT
OTHER TERMINALS. EVEN WITH A PASSING SHOWER OR STORM, VSBYS AND
CIGS ARE LIKELY TO REMAIN VFR WITH ONLY A LOW PROBABILITY FOR
BRIEF MVFR CONDITIONS. OTHERWISE WINDS WILL REMAIN MUCH LIGHTER
TODAY COMPARED TO RECENT DAYS WHILE VFR CONDITIONS PERSIST. WILL
SEE PERIODS OF MID-LEVEL CIGS BUT WELL WITHIN VFR RANGE.
