BOISE, Idaho — The system that brought cool, cloudy, and at-times wet weather to our area on Thursday drifted eastward overnight, allowing skies to clear and setting the stage for a perfectly pleasant Friday afternoon. Temperatures will rebound back closer to normal today, with highs in the mid- to upper 60s in the Treasure Valley with abundant sunshine to wrap the work week. If you've got any yard work to get done or a lawn that needs to be mowed, today will a perfect day to get outside!
Over the weekend, get ready for some 'weather whiplash' as we've got a mild but very windy Saturday on tap ahead of a dramatic cooldown for Sunday, courtesy of a strong storm system that will dive south into the Pacific Northwest early in the weekend. Winds will start howling as early as Friday night ahead of the strong and unseasonably cold system, with gusts up to 40mph possible by Saturday morning. A potent cold front moving west to east will trigger rain in eastern Oregon by early afternoon Saturday, with wet weather rolling into the Treasure Valley by dinnertime Saturday and sticking around through the overnight hours. Some forecast models are indicating up to 1" of precipitation could fall from late Saturday through Monday, so get the umbrella and the rain boots ready now and feel free to turn off those sprinklers as well.
Snow levels start off high, around 6,500' Saturday, but quickly lower to 3,500' by Sunday as cold air moves in behind the front. Several inches of accumulation are possible above 5,000' by Monday morning so plan on winter driving conditions if headed to the high terrain Sunday and Monday.
Off-and-on rain showers will linger into Sunday across the lower elevations, and temperatures plummet on Sunday as well. High temps in Boise go from around 70° on Saturday to just the low 50s on Sunday; Twin Falls could cap a just 47° on Sunday after reaching 72° tomorrow!
The cold-core system slowly exits east on Monday, supporting valley rain and mountain snow chances possibly into Tuesday, along with blustery winds east of Boise. Then, sunshine and warmer temps finally make a return by the middle of next week.
