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 PRECIPTATION 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.
AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
ISSUED AT 512 AM MDT TUE JUN 30 2026
A TROUGH WILL BE INCHING CLOSER TO IDAHO FROM THE WEST. IT WILL
PROVIDE ENOUGH INSTABILITY THAT A CHANCE OF TSRA AND SHRA WILL
DEVELOP FOR THE AFTERNOON. WHILE THE SHOWERS CAN BE ANY
AIRDROME, ONLY KSUN AND KDIJ ARE AT SERIOUS RISK OF TSRA, ENOUGH
TO WARRANT A PROB30 GROUP. SHRA BARELY GETS A VCSH REMARK. KIDA
ACTUALLY HAD A BRIEF EPISODE OF BR, SO HAVE VCFG IN THE FIRST
FEW HOURS THIS MORNING.
WIND IS VERY LIGHT, SOME PLACES LIKE KBYI TAKING UNTIL 30/21Z TO
DEVELOP A SLOPE-VALLEY WIND. HAVE 15KT PEAK SUSTAINED WIND, BUT
EVEN THAT IS A LITTLE HIGH FOR KIDA AND KPIH. THIS IS OUTSIDE OF
TSRA.
CIGS SHOULD STAY SOLID VFR, WITH THE STORMIEST TAFS HAVING THE
POSSIBILITY OF 4000FT AGL CIGS; KDIJ THE LIKELIEST AND KSUN A
DISTANT SECOND.
NO IMPACT TO VSBY EXPECTED, UNLESS THE FOG RE-DEVELOPS IN THE
NEXT COUPLE OF HOURS.
FIRE WEATHER
ISSUED AT 144 AM MDT TUE JUN 30 2026
AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS CONTINUE THROUGH FRI
AFTERNOON, ALTHOUGH BY THEN IT WILL MAINLY BE IN SOUTHERN AND
EASTERN HIGHLANDS. THE HOLIDAY SHOULD BE WARM, DRY, AND QUIET
WIND-WISE, WITH NO THREAT OF THUNDERSTORMS OR ANY PRECIPITATION.
THE ONLY SIGNIFICANT WIND WILL BE ON FRI AFTERNOON, WHEN
TEMPERATURES ARE STILL NEAR NORMAL FOR THE TIME OF YEAR. SHOWERS
AND THUNDERSTORMS RETURN AFTER THE HOLIDAY WEEKEND IS OVER, ON
MON.
