DISCUSSION

Issued at 134 PM MDT Sat Apr 11 2026

Showers and thunderstorms are moving through the area today as moisture continues to be pushed our way by the low moving inland towards northern California today. SPC has a good portion of our CWA included in the Marginal risk for severe storms today. Main threat will be strong wind gusts to 60 mph and small hail with storms. We've already seen a few storms in the southeast corner produce gusts around 50 to 55 mph. Gusts outside of storms today will be closer to 20 to 30 mph through the Snake River Plain and Eastern Highlands. It will be quite breezy on Sunday, outside of thunderstorm activity, especially in parts of the Snake River Plain, South Hills and Eastern Highlands with gusts again around 30 to 40 mph, though wouldn't be surprised to see some gusts closer to 45 mph. We will be brushing right up against WIND ADVISORY criteria with about a 30-40 percent chance of maximum gusts reaching 50 mph in these areas tomorrow. Our aforementioned low will be over northern CA on Sunday and working eastward, bringing these gusty winds and more showers and thunderstorms on Sunday. Snow levels will fall to near 7500 feet by Sunday morning. Highs on Sunday will again be in the upper 50s to low 60s before we cool down for most of the week ahead. Between showers and storms today through Monday, models are showing about a tenth to a quarter inch of liquid precipitation in the eastern Magic Valley and Snake River Plain. In the mid to upper elevations, those totals will be closer to a quarter to a half inch with a few spots closer to three quarters of an inch, though that will be more likely for spots that have thunderstorms pass directly overhead. Snow levels will continue to fall and be near 5000-5500 ft by Monday morning as the low moves over Eastern Idaho and transitions into more of a deep trough than a closed low. Mountain snow is still in the forecast, though it has decreased slightly for the Eastern Highlands and increased slightly for the Central Mountains. Most of it will fall at and above pass levels with 3-5 inches total from Sunday morning to Monday morning around Galena Summit and 1-3 inches near Emigration Summit.

By Tuesday, a few showers will linger in the Eastern Highlands as the trough continues to march eastward into Wyoming and highs will be in the mid 50s for Tuesday and Wednesday afternoons. Look for increasing winds on Wednesday ahead of our next low and cold front dropping in from British Columbia. Gusts in the upper Snake River Plain already look to be in the 35 to 45 mph range, so will likely need a WIND ADVISORY for Wednesday, but we will see how that evolves over the next several days. This system will bring yet more precipitation for the area and another drop in temperatures for Thursday and Friday.
