.DISCUSSION...
Issued at 303 AM MDT Sat May 9 2026

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.
