DISCUSSION

Issued at 1224 PM MDT Mon Apr 27 2026

General low pressure over the western US will keep showers in the forecast for MOST of the upcoming week and weekend. Friday looks bone dry at the moment due to high pressure quickly shifting across the state. On a daily basis, precipitation amounts do not look extremely heavy. This includes rain, snow, and graupel. That said, a heavier cluster or band of precipitation can settle across a particular area, and produced enough impacts to travel and such.

The biggest impact through midweek is cold overnight temperatures. We are expecting another widespread freeze tonight, except for a few locations dropping to just above freezing. We will see a warming trend, but it still appears the frost and freeze conditions will occur over portions of central and eastern Idaho. There is another FREEZE WARNING for tonight across the Snake Plain and Magic Valley. It is likely the same areas will need another headline for tomorrow night. We may finally NOT need any type of frost or freeze headline by the time we reach Friday morning. We will need to see if our Blend of Models is warming things up too quickly, but current trends quickly returns us to widespread 60s and 70s for highs during the latter half of the week.
