.DISCUSSION...
Issued at 314 AM MDT Sat May 2 2026

After a chilly start to the day across they Magic Valley and
Snake River Plain, we will warm, dry conditions today. Most
locations in the Snake River Plain and Magic Valley will be in
the 70s for highs today. This morning should be the final
morning for frost/freeze alerts with temps expected to hold in
the upper 30s across the Snake Plain. There`s an outside chance
for a few showers Sunday afternoon as a low pressure system
slowly advances toward the California coast. Better chances for
precipitation Monday into Tuesday as the low moves inland and
interacts with a weak system passing just to our northeast. This
weak system will help to draw up some moisture from the
southwestern U.S. low. Still, expect mainly light, scattered
precipitation. Temps cool back down for Tuesday with potential
for another frost/freeze situation Tuesday night into Wednesday
morning. Then, a ridge builds back into the region for the
second half of the week with warming temps once again.
