.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.
