SHORT TERM...Tonight through Sunday night...An upper ridge over the region will bring early summer like temperatures through the weekend. The warmth will peak on Sunday, bringing high temperatures to around 15 degrees above normal. This will place the valleys into the mid-80s with mountain valleys in the upper 70s. Winds will ramp up on Sunday afternoon/evening across open terrain as flow aloft increases. LONG TERM...Monday through Friday...An upper trough will track across the region Monday bringing a 15% chance of showers and thunderstorms to higher terrain of s-central Idaho, mainly south of the Snake River Plain. Otherwise the trough passage is dry and marked by gusty winds and slightly cooler temperatures from Monday. Deterministic models quickly fall out of agreement after Monday. There is little change in ensemble consensus which is to keep the area under dry northwesterly flow along the east side of an upper ridge. This pattern will keep temperatures well above normal through the week. && .BOI WATCHES/WARNINGS/ADVISORIES... ID...None.
