UPPER LEVEL TROF WHICH BROUGHT THE SHOWERS AND ISOLATED
THUNDERSTORMS YESTERDAY CONTINUES TO PUSH RAPIDLY EAST. WILL
HAVE MUCH DRIER AND WARMER CONDITIONS TODAY WITH SKIES BECOMING
SUNNY AFTER SOME PATCHY FOG THIS MORNING. WILL SEE THE WARMEST
TEMPERATURES OF THE WEEK THURSDAY AND FRIDAY WITH MANY LOW
ELEVATION LOCATIONS NEAR 80 DEGREES. A COLD FRONT WILL MOVE
THROUGH EASTERN IDAHO FRIDAY AND EXPECT BREEZY TO WINDY
CONDITIONS WITH HIGHS AGAIN NEAR 80 IN LOWER ELEVATIONS. BEHIND
THE COLD FRONT IT WILL BE MUCH COOLER OVER THE WEEKEND WITH
HIGHS SATURDAY IN THE 50S MOUNTAINS AND 60S VALLEYS. THERE WILL
ONLY BE A SLIGHT CHANCE FOR SHOWERS AND THUNDERSTORMS SUNDAY AND
MONDAY BUT NOT EXPECTING ANY SIGNIFICANT AMOUNTS.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 920 PM MDT TUE SEP 22 2026
MAIN CONCERN OVERNIGHT IS LOW STRATUS AND FOG FORMATION WHICH
THE HRRR INDICATES COULD DEVELOP ALONG THE SNAKE RIVER WHICH
COULD IMPACT IDA, PIH AND BYI. THE NBM SHOWS THIS DEVELOPING AS
WELL. WITH LIGHT WINDS, COOL TEMPERATURES AND PLENTY OF MOISTURE
AROUND, FOG IS A STRONG POSSIBILITY. VERY UNCERTAIN ON TIMING
OF WHEN IT WOULD DEVELOP. NEED CLOUD COVER ASSOCIATED WITH THE
UPPER LOW TO EXIT THE TAF SITES. SO MOST LIKELY LATE IN THE
NIGHT, PERHAPS AS LATE AS 12Z.
FIRE WEATHER
ISSUED AT 239 AM MDT WED SEP 23 2026
WILL HAVE DRY CONDITIONS WITH MINIMAL IMPACTS TODAY AND
THURSDAY. A COLD FRONT WILL APPROACH FRIDAY AND EXPECT SOME MUCH
WINDIER CONDITIONS ESPECIALLY IN THE AFTERNOON. ALTHOUGH IT WILL
BE MUCH DRIER MOST MINIMUM HUMIDITY WILL REMAIN OVER 20 PERCENT.
EXPECT COOLER CONDITIONS SATURDAY INTO NEXT WEEK AFTER VERY WARM
TEMPERATURES TODAY THROUGH FRIDAY. NOT EXPECTING RED FLAG
CONDITIONS FOR THE NEXT WEEK.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
