DISCUSSION

Issued at 201 AM MDT Thu Apr 9 2026

Building pressure overhead will allow daytime temperatures to warm by several degrees today and again on Friday, bringing highs to around 15 to 20 degrees above climatological normal, into the mid- 70s across the low elevations. Weak moisture associated with an upper low off the CA/OR coast will be filtered into ID in southwest flow through early next week, with PoPs and isolated thunderstorm chances increasing in both coverage and probability through the weekend. Probability of thunder will roughly range 15 to 25 percent over the course of the weekend. The ridge over Idaho will be flattened come Saturday as a descending low merges with the now open trough and the system shifts further inland. 700mb winds will increase to roughly 25 to 35 kts late Friday through Saturday, with the National Blend indicating max wind gusts ranging 35 to 45 mph both Saturday and Sunday. The weekend cold front will result in seasonable temperatures beginning Sunday, becoming slightly cooler than normal early next work week. While snow levels will initially be over 8,500 feet, they will drop to as low as 5,500 feet on Sunday and Monday behind the cold front. National Blend 72-hour precipitation through Tuesday ranges 0.30" to 0.40" across the Snake River Plain with around half an inch to 0.80" in the central mountains, southern highlands, and eastern mountains. NBM snow totals range 2 to 7 inches in the central mountains, Albion Mountains, and Bear River Range, with up to around 5 inches in the Centennials, Caribou Range, and Big Holes.
