DISCUSSION

Issued at 122 PM MDT Tue Apr 28 2026

Will have some rain showers with some graupel as well as high elevation snow showers late this afternoon which will end this evening as sunset approaches. Expect clearing overnight with again freeze warnings in effect for the Snake River Plain and Arco Desert as well as northern parts of the Eastern Magic Valley. A frost advisory is in effect for the southern parts of the eastern Magic Valley. High temperatures Wednesday will rise slightly with some upper 50s to lower 60s in lower elevations with 30s and 50s mountains. Will have a threat for afternoon showers once again with some isolated thunderstorms as well. May still see some near freezing low temperatures Wednesday night but think may only need some frost advisories Thursday morning as we start to see the warming trend take effect.

All lower elevations should reach into the 60s for highs on Thursday with showers mainly limited to the southeast mountains. Friday will be the likeliest day for a completely dry dry with highs in lower elevations will above normal in the upper 60s to lower 70s with mainly 60s mountains. Saturday through Tuesday look extremely warm with high temperatures as much as 15 degrees above normal with 70s throughout lower elevations and mainly 60s in the mountains. After another dry day Saturday the threat for showers and isolated thunderstorms returns Sunday through next Tuesday.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1105 AM MDT Tue Apr 28 2026

Overall, VFR conditions are expected at all sites through the afternoon and tonight. DIJ has been the exception this morning with clouds SCT to BKN at 025. Clouds should lift back to VFR levels this afternoon. Isolated to scattered showers are expected to pop up this afternoon, though most of our sites should not be impacted. Best chance (~30 percent) for a shower at a terminal is at DIJ where VCSH remains in the forecast. The chance is closer to 10-15 percent at all other sites, so have left it out of the TAF.
