Area forecast discussion National Weather Service Spokane Washington 1106 am PST Sat Dec 20 2014 Synopsis... a more active weather pattern will continue into early next week. Another wet and robust weather system will bring snow to the mountains with mainly rain for the valleys today and tonight. Temperatures are expected to remain above average through early next week...before dropping down toward normal values by Christmas day. && Discussion... morning update: messy forecast pattern. A warm front is draped across the region this morning and impulses riding along it will bring occasional rain and snow. Short-range guidance, such as the hrrr and hi-res NAM, have been showing one wave of precipitation pushing across the region from mid-morning to early afternoon, followed by brief break, before another broader wave of precipitation comes in from mid to later afternoon into this evening. That precipitation comes with the mid-level shortwave riding in on the nose of the jet stream, before things begin to dry out from the west overnight into Sunday morning so that by afternoon the main precipitation will be near the Cascades crest and over Idaho, particularly the central Panhandle mountains, through the Blue Mountains. Winter weather advisories remain in place for the Cascade mountains and valleys, with the most significant snows expected both near the crest and north of Lake Chelan. This is where some of the colder air remains, though even the most guidance that keeps snow levels lowest tends to bring them up a bit through this afternoon into tonight. Places like the Methow Valley, including areas near Twisp, have reported around 4 inches of snow so far and spots could pick up another 4 to 6 inches through this evening, with locally higher amounts in the higher terrain, before the rates start to wane as the drier air comes in overnight into Sunday morning. Winds are expected to increase with this system, especially overnight into Sunday when drier air and mixing comes with the mid-level disturbance riding that jet. Right now this is not prime timing for thinking any wind highlights will be needed. But it will be monitored. /J. Cote' && Aviation... 18z tafs: periods of mainly rain expected around taf sites from mid morning to early afternoon and again from late afternoon into tonight, before precipitation starts to wane from the west overnight into Sunday. Look for MVFR/IFR conditions. Winds are expected to increase later this evening into Sunday. We will have to monitor for possible llws, if the atmosphere fails to mix effectively this evening into Sunday morning. /J. Cote' && Preliminary point temps/pops...
