Area forecast discussion National Weather Service Boise Idaho 912 PM MDT Wednesday Sep 2 2015 Discussion...cold front is moving through the area as anticipated...with its current location being just east of Mountain Home and moving east-southeast. Northwest winds prevail behind the front. Model guidance continues to show the bulk of associated precipitation lifting north of the central mountains...but chances remain here in the mountains overnight and Thursday. No changes made to the afternoon forecast...as conditions look in line with the current grids. && Aviation...VFR. Locally gusty northwest surface winds trailing a cold front this evening. Gusts will diminish by 06z with steady northwest winds continuing overnight. Light showers accompanied by middle-level ceilings across east-central Oregon and west-central Idaho will persist over west-central Idaho mountains through Thursday. Weekend outlook...cutoff low pressure system will bring periods of rain...low VFR and local MVFR ceilings to southeast Oregon and SW Idaho Friday and Saturday. VFR conditions with decreasing clouds on Sunday. && Previous discussion... short term...tonight through Friday...a cold front was situated over central and northeast Oregon...east of Baker City but just west of Burns. The front is still on track to move through the remainder of southeast Oregon and SW Idaho overnight. Southwest winds gusting to 35 miles per hour this after-evening will switch to northwest with the frontal passage. A slow-moving narrow band of showers will lag behind the front and reach portions of southeast Oregon and far north portions of SW Idaho overnight. Temperatures will be 10-15 degrees cooler on Thursday. Locally breezy northwest winds will continue through Thursday afternoon. The aforementioned band of showers will continue to track slowly to the east on Thursday. Precipitation amounts will be light tonight-Thursday...with the best chance for measurable rain across the northern mountains an upper low in southern British Columbia will dive south...with the center of the low moving into western Oregon on Friday. The low will bring a chance of showers to southeast Oregon by the afternoon. Meanwhile...a band of showers will also develop over central Idaho. Instability will be marginal on Friday...but enough to carry a slight chance of afternoon thunderstorms. High temperatures Friday will be within a few degrees of Thursday/S highs. Winds are expected to be lighter on Friday. Long term...Friday night through Wednesday...unseasonably cool upper level trough will trek across the Great Basin Friday night into Sunday. Models in good agreement with the center of the trough moving across southeast Oregon and southwest Idaho. Expect precipitation amounts of 0.25 to 0.50 in the west central mountains with this system and valley amounts up to 0.20 in. Snow levels will fall to around 8000 feet mean sea level in the core of the system with the highest peaks receiving snow. Drier air moves into the region by Sunday for the remainder of the extended period. Temperatures Saturday will be around 15-20 degrees below normal slowly warming to around 5 degrees below normal by Tuesday and Wednesday. && Boi watches/warnings/advisories... Idaho...none.
