Area forecast discussion National Weather Service Boise Idaho 851 PM MST Thursday Dec 18 2014 Discussion... abundant moisture off the coast in association with the next cold front is expected to push into eastern Oregon overnight and into western Idaho middle morning through early afternoon. The associated warm front moved into eastern Oregon early this evening and is now moving into central Idaho. This will keep snow off and on in McCall this evening. This sould be a good event for the mountain regions with generally 3 to 6 inches of snow expected through the end of the day Friday. This all handled well in the current forecast. Have made a few changes to the forecast to increase overnight temperatures slightly across the forecast area along with increasing the winds. && Aviation...scattered MVFR snow showers will continue over the higher terrain of southeast Oregon and the central Idaho mountains. Areas of snow with rain below 4k feet mean sea level will spread across eastern Oregon into the central Idaho mountains after 06z and all of southwest Idaho after 12z with warm frontal passage. MVFR/IFR conditions with snow...MVFR/low-VFR conditions in rain. Surface winds...south- southeast around 10 kts. Winds aloft... southwest 15-25 kts up through 10k feet mean sea level. Weekend outlook...brief break in the precipitation Friday night will be followed by widespread precipitation starting in eastern Oregon late Saturday morning and spreading across the entire area by Saturday evening lasting through Sunday afternoon. Snow levels 4000- 4500 feet mean sea level Saturday morning will rise to 6000-8000 feet by Saturday afternoon/evening. Valleys will remain as all rain but will likely see MVFR ceilings Saturday night through Sunday morning. && Previous discussion... short term...tonight through Saturday...short wave ridge will move through overnight...and in it/S wake we will begin the first of two notable changes in the weather pattern impacting the Pacific northwest. Strong moist flow will move in behind the short wave ridge. This will begin a period of moderate to heavy precipitation that will last into the long term. The first wave will move in Friday. We have continued the trend of increasing probability of precipitation as confidence increases. Precipitation will spread from west to east tonight...getting into all of SW Idaho by tomorrow afternoon. Rainfall amounts will range from 0.10 to 0.20 in lower elevations...with even more at higher elevations. Temperatures will be still be above normal...but several degrees cooler than today. Friday night we will see a relative break in the action. On Sat...an even wetter system will begin moving into the region. Light to moderate rainfall will move into eastern Oregon early in the day...and into SW Idaho mainly in the afternoon. Conditions in Boise from middle afternoon into the early evening will be cool and rainy...with temperatures in the lower 40s. Heavier precipitation will come Saturday night. Long term...Saturday night through Tuesday...a moist flow from the Pacific will keep our area mild wet and cloudy through Monday. Snow levels will range from 4000 to 5000 feet Saturday evening then rise to around 6500 feet in central Idaho and as high as 8000 feet in southeast Oregon by Sunday afternoon. Rainfall totals of half an inch or more are expected in the valleys...falling mainly Saturday night through Sunday evening. New snow accumulations of 12 to 18 inches are likely above 6500 feet by Monday night in the mountains of central Idaho and Baker County Oregon. Monday night and Tuesday an upper level ridge building north and east from California will bring a drying trend with scattered showers confined mainly over the mountains. Temperatures will average around 15 degrees above normal. Tuesday night through Thursday...the region will begin this period in a moist northwesterly flow...but will come under the influence of a moist/cold shortwave by Wednesday evening. This shortwave will bring a chance of precipitation to the entire region and will continue doing so until Christmas morning. Areas in southeast Oregon and the Treasure valley will be the first to dry out while higher elevations and the Magic Valley will continue to experience a slight chance of precipitation through Christmas night. Precipitation could come in the form of snow /including the valleys as temperatures and snow levels drop/ by Wednesday night. Temperatures during this period will begin about 5 degrees above normal but will drop to normal by Thursday. && Boi watches/warnings/advisories... Idaho...none. Or...none. && $$ Weather.Gov/Boise Discussion...CR aviation.....Js previous short term...snow pellets previous long term....jt/ab
