ISSUED AT 155 AM MDT FRI APR 24 2026
SOME RESIDUAL SHOWERS CONTINUE THIS MORNING AND SHOWERS WILL
REGENERATE IN THE UNSTABLE AIR THIS AFTERNOON. THUNDERSTORMS ARE
POSSIBLE IN A SMALL AREA ALONG THE ID-WY BORDER THIS AFTERNOON.
SNOW ACCUMULATIONS ARE VERY LIGHT, STAYING BELOW 3 INCHES EVEN
IN THE HIGHEST ELEVATIONS IN THE EASTERN HIGHLANDS FOR THE NEXT
24 HOURS. SHOWERS SHOULD END PRIOR TO MIDNIGHT TONIGHT. SKIES
CLEAR AND THIS WILL ALLOW TEMPERATURES TO PLUMMET. EVERYWHERE IN
THE FORECAST AREA TONIGHT WILL BE BELOW FREEZING; A FREEZE WATCH
HAS BEEN ISSUED FOR THE 5 ZONES THAT MAKE UP THE FREEZE-FROST
DISTRICT. MUCH MORE SUNSHINE WITHOUT THE EVAPORATIVE COOLING OF
PRECIPITATION WILL ALLOW AFTERNOON WARMING TO RESUME AFTER A
CHILLY AFTERNOON ON FRI. THE THREAT OF PRECIPITATION RETURNS
LATE SAT NIGHT AND CONTINUES SUN MORNING AS ANOTHER SHORTWAVE
ENTERS THE WEST SIDE OF THE MAIN TROUGH OVER SOUTH CENTRAL
CANADA AND BRINGS CLOUDS AND PRECIPITATION BACK TO THE NORTHERN
ROCKIES. THIS AIR MASS IS CONTINENTAL POLAR IN NATURE AND LITTLE
PRECIPITATION IS EXPECTED, SAVE FOR AREAS ALONG THE ID-UT BORDER
THAT MAY BE ABLE TO PULL UP SOME MOISTURE FROM THE SOUTH. THE
CLOUD COVER SUN NIGHT ENDS THE STRING OF FREEZE WARNINGS, BUT
THE AIR MAY BE COLD ENOUGH FOR A FROST ADVISORY IN THE DISTRICT.
THE ONE ELEMENT NOT PRESENT IN THIS SHORT TERM FORECAST IS
STRONG WIND. AS FREEZE WARNINGS WOULD IMPLY. THE AIR IS FAIRLY
CALM AT NIGHT, WITH AT BEST SOME BREEZY AFTERNOONS, BUT GUSTS
SHOULD STAY MAINLY BELOW 30 MPH.
MON THROUGH THU. MON STILL HAS THE NEARLY STATIONARY UPPER LEVEL
LOW IN SOUTH CENTRAL CANADA, AND IT KEEPS THE TROUGHING OVER THE
FORECAST AREA INTO MON AND TUE. SO SLIGHT CHANCE TO CHANCE
PROBABILITIES FOR PRECIPITATION CONTINUE THROUGH TUE NIGHT. BY
AN APPROXIMATE 75 PERCENT-25 PERCENT SPLIT IN THE CLUSTERS, THE
CANADIAN LOW HAS MOVED FAR ENOUGH EAST TO NOT BE A FACTOR AND A
TROUGH OVER THE DESERT SOUTHWEST HAS NO INFLUENCE. TEMPERATURES
FINALLY RETURN TO NORMAL AT THIS POINT AND WIND IS EVEN LIGHTER.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1218 PM MDT FRI APR 24 2026
CONTINUING TO SEE CLOUDS ROTATING THROUGH THE BROAD BASE OF AN
LARGE UPPER LEVEL TROUGH. STARTING TO SEE SOME SHOWERS
DEVELOPING WHICH COULD POSE BRIEF IMPACTS TO KPIH, KIDA AND KDIJ
OVER THE NEXT FEW HOURS. LOCALIZED MVFR/IFR REDUCTIONS WILL BE
POSSIBLE WITH RAIN OR SNOW. KSUN AND KBYI SHOULD AVOID ANY
ISSUES WITH PRECIP AND HAVE BEGUN TO SEE SOME CLEARING ALREADY.
EXPECTING SKIES TO CONTINUE CLEARING LATER THIS EVENING AND INTO
THE OVERNIGHT FROM WEST TO EAST WITH VFR EXPECTED AT ALL SITES
BY LATER THIS EVENING AND CERTAINLY INTO THE DAY SATURDAY.
BREEZY WINDS CONTINUE THIS AFTERNOON, NAMELY AT KBYI AND TO A
LESSER EXTENT KPIH, BUT THESE SHOULD BECOME MORE LIGHT AND
VARIABLE REGIONWIDE AS WE MOVE INTO THE EVENING AND THIS TOO
WILL CONTINUE INTO SATURDAY.
PIH WATCHES/WARNINGS/ADVISORIES
FREEZE WARNING FROM 9 PM THIS EVENING TO 10 AM MDT SATURDAY
