SHORT TERM /THROUGH FRIDAY NIGHT/
ISSUED AT 128 PM MDT THU OCT 16 2025
EAST IDAHO REMAINS UNDER THE INFLUENCE OF AMPLIFIED UPPER
TROUGH, NOW SHIFTING EAST INTO THE ROCKIES AND PLAINS PER
SATELLITE IMAGERY. WRAP AROUND MOISTURE AND NORTH/NORTHWESTERLY
FLOW ARE HELPING TO KEEP SHOWERS IN PLACE ACROSS THE REGION THIS
AFTERNOON. SNOW ACCUMULATIONS WILL REMAIN LIGHT AND GENERALLY
ABOVE 7000 FT ELEVATION. OUTSIDE OF SHOWERS, LOW CLOUDS, PATCHY
FOG, AND BREEZY WINDS ALSO CONTINUE. SHOWERS LINGER THIS EVENING
MAINLY EAST OF I-15, THEN TAPER TO ISOLATED SHOWERS MAINLY
HIGHER ELEVATIONS ALONG THE WY BORDER FOR THE REMAINDER OF THE
NIGHT. LOW CLOUDS OVERNIGHT WILL KEEP LOWS AROUND OR JUST ABOVE
FREEZING FOR MOST LOWER ELEVATION AREAS. POCKETS OF FOG ARE
POSSIBLE, BUT MODEL SOUNDINGS GENERALLY SUPPORT STRATUS OVER
FOG. AT THIS TIME, DENSE FOG IS NOT ANTICIPATED OVERNIGHT. NBM
PROBABILITIES SUPPORT A 10-15% CHANCE OF VISIBILITIES AS LOW AS
3 MILES OVERNIGHT AND EARLY FRIDAY IN VERY FEW LOCATIONS. A WEAK
SHORTWAVE CROSSES THE IDAHO PANHANDLE INTO MONTANA FRIDAY NIGHT
INTO EARLY SATURDAY FOR SOME SHOWER POTENTIAL ACROSS THE ISLAND
PARK/YELLOWSTONE REGION. OTHERWISE EAST IDAHO WILL TREND TOWARD
DRIER AND SUNNIER WEATHER HEADED INTO THE WEEKEND.
LONG TERM /SATURDAY THROUGH WEDNESDAY/
ISSUED AT 128 PM MDT THU OCT 16 2025
WEAK RIDGING WILL BE OVER THE AREA TO START THE DAY ON SATURDAY
WHICH SHOULD KEEP THINGS DRY ACROSS EASTERN IDAHO ALONG WITH MOSTLY
CLEAR SKIES AND DRY WEATHER. TEMPS WILL BE ON THE COOLER SIDE OF
NORMAL BY A FEW DEGREES, GENERALLY UPPER 40S TO UPPER 50S,
THROUGHOUT THE REGION. SOUTHERLY FLOW WILL INCREASE DURING THE
OVERNIGHT HOURS INTO SUNDAY AHEAD OF AN APPROACHING TROUGH THAT'LL
SWING NORTH OF THE AREA. MODELS HAVE BEEN TRENDING POPS AND QPF BACK
A BIT NOW WITH THIS FEATURE LOOKING TO STAY MORE TO THE NORTH
COMPARED TO A FEW DAYS AGO. WE'LL STILL INCREASED CLOUD COVER AND
SOME HIGH ELEVATION PRECIP CHANCES BUT NOT SURE NOW HOW MUCH PRECIP,
IF ANY, WILL BE SEEN ACROSS THE SNAKE PLAIN AND MAGIC VALLEY. IT
WILL HELP BRING COOLER TEMPS BACK INTO THE AREA THOUGH AFTER A MORE
MILD SUNDAY IS EXPECTED. HIGHS ON MONDAY WILL LIKELY STRUGGLE TO
CLIMB ABOVE 50 THROUGHOUT MUCH, IF NOT ALL, OF EASTERN IDAHO. UPPER
FLOW LOOKS TO BECOME MORE ZONAL ON TUESDAY IN THE WAKE OF THE
AFOREMENTIONED TROUGH WHICH SHOULD KEEP THE FORECAST MOSTLY DRY BUT
TEMPS WILL BE SLOW TO MODERATE INTO THE MIDDLE PART OF NEXT WEEK
WITH HIGHS MAINLY IN THE 50S EXPECTED.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1150 AM MDT THU OCT 16 2025
STILL SEEING LINGERING LOWER CLOUDS ACROSS REGION THIS AFTERNOON
INCLUDING SOME STRATUS BARELY SNEAKING INTO KSUN WITH THE
SOUTHERLY FLOW PUSHING SOME OF IT UP THE VALLEY. IN THEORY,
SHOULD SEE SOME CLEARING AT ALL TERMINALS, EXCEPT KDIJ, OVER THE
NEXT FEW HOURS ALLOWING FOR MORE MVFR OR LOW END VFR TO PREVAIL
INTO THE EVENING HOURS BEFORE THE CLEARING SHOULD IMPROVE MORE
AS WE GET CLOSER TO THE OVERNIGHT. COULD HAVE SOME TROUBLE WITH
OVERNIGHT STRATUS/FOG THOUGH WITH RECENT RAINFALL KEEPING
MOISTURE TRAPPED IN THE LOWER LEVELS SO THIS WILL BE SOMETHING
TO WATCH OVERNIGHT AND INTO THE AM HOURS ON FRIDAY. CURRENT
FORECAST HINTS AT THIS POTENTIAL BUT KEEPS THINGS VFR FOR THE
TIME BEING. WE'LL HAVE TO SEE WHERE THINGS TREND OVER THE NEXT
FEW HOURS.
FIRE WEATHER
ISSUED AT 253 AM MDT THU OCT 16 2025
RAIN AND SNOW SHOWERS WILL TAPER OFF FROM WEST TO EAST TODAY AS
THE RESPONSIBLE LOW PRESSURE SYSTEM PULLS AWAY FROM THE REGION.
EXPECT A BRIEF BREAK WITH MOSTLY DRY CONDITIONS FRIDAY AND
SATURDAY, BEFORE OUR NEXT TROUGH BRINGS ANOTHER ROUND OF
PRECIPITATION TO THE REGION FROM SUNDAY AFTERNOON THROUGH
MONDAY. WINDS MAY BE A BIT BREEZIER WITH THIS NEXT SYSTEM.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
