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.
