BOISE, Idaho — The wet, windy, and unsettled weather from the weekend will linger into the new work week, as a broad area of low pressure continues to slowly drift to the east on Monday. With an unstable and moist atmosphere in play, though, that sunshine could help trigger some thunderstorms this afternoon and evening across eastern Oregon and SW Idaho. Bursts of rain, hail or graupel, along with gusty winds, could limit visibility at times in the vicinity of these storms.
Brisk, blustery winds will continue to blow across southern Idaho today, especially in the Magic Valley where a WIND ADVISORY is in effect 8ntil 6pm for gusts up to 45mph. The Treasure Valley will likely endure gusts up to 30mph. Northwesterly flow aloft will keep us cool again today with temperatures climbing to near 60° in Boise, a good 10° cooler than normal for early May.
Tonight, another fast-moving cold front will march across the Gem State, leading to more rain and snow overnight into Tuesday and ushering in the coolest conditions of the week. High temps for Tuesday will cap at just 53° in Boise with a cold northwest wind making it feel chillier. A couple inches of snow are possible in the central mountains around 4,000' over the next 24 hours, with up to 8" possible on the highest peaks by Tuesday morning. A few snowflakes are even possible down into the Boise foothills Tuesday as overnight lows dip into the mid-30s in the Treasure Valley.
By mid-week, the cool and unsettled weather takes a hike as a strong ridge of high pressure starts amplifying in from the west. This ridge will bring unseasonably warm weather to the region, with portions of British Columbia and the Pacific Northwest possibly seeing record-setting warmth this weekend. In SW Idaho, temperatures will skyrocket into the mid-70s by Friday and then into the 80s over Mother's Day weekend! This warmth is more typical of mid-June than mid-May and will be picture-perfect for any outdoor brunch or dinner plans that you're planning for Mom on Sunday.
