Will have slightly cooler conditions today but still warm with highs in the 60s mountains and 70s valleys. Upper ridge builds in Sunday with very warm conditions Sunday through Wednesday. Highs tomorrow into the 80s low elevations and 60s and 70s mountains. By Tuesday many low elevations will reach the lower 90s. And even some mountain areas will hit the 80s. It will be the warmest day of spring so far. No precipiation is expected through Tuesday. Ridge moves east Wednesday and southerly flow aloft increases which should return some moisture and allow at least a slight chance of showers and thunderstorms late Wednesday into next Saturday.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1013 AM MDT Sat May 9 2026

High pressure continues unlimited VSBY, while three airdromes for the 24 hour period will have nothing but SKC. The other two, KIDA and KDIJ, have SKC for some of those hours, but some cumulus at 4000ft to 7000ft AGL. KIDA is the only airdrome where the sky condition has SCT rather than SKC or FEW.

Finally, wind is the major reason for any FM groups. Vertical mixing due to insolation is already starting to bring wind to 15KT. This is expected at KSUN, already happening at KPIH, KIDA, and KBYI. However by late evening wind should be below 8KT.
