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 /12Z TAFS THROUGH 12Z SATURDAY/
ISSUED AT 519 AM MDT FRI APR 24 2026
KIDA AND KDIJ STILL HAVE ISSUES WITH SHSN IN THE AREA, REDUCING
VSBY AND CIG TO MARGINAL VFR FOR BOTH AT LEAST, WITH KDIJ
POSSIBLY GOING IFR FOR VSBY. FOR THE THREE SOUTHERN AIRPORTS,
THE SHSN/SHRA HAVE ENDED IN THIS REGION MOSTLY, EXCEPT KPIH MAY
SEE SHRA DEVELOP IN THE NEARBY MOUNTAINS. KSUN, KPIH, AND KBYI
ALL STAY VFR.
WIND IS DOWN AGAIN CONSIDERABLY, WITH ONLY KBYI
RAMPING UP AGAIN TO 20G30KT. MOSTLY EXPECTED DIRECTIONS,
ALTHOUGH A LOW MOVING THROUGH HAS PUSHED WIND AT KSUN TO
SOUTHERLY THIS MORNING. HOWEVER, AS IT PASSES TO THE WEST IT
SHOULD SHIFT TO NORTHWEST BY LATE MORNING AND STAY THAT WAY
THROUGH TONIGHT.
PIH WATCHES/WARNINGS/ADVISORIES
FREEZE WARNING UNTIL 10 AM MDT THIS MORNING FOR IDZ051>055.
