Area forecast discussion National Weather Service Spokane Washington 1000 PM PST Friday Nov 28 2014 Synopsis... a showery and breezy weather pattern will continue over far eastern Washington and the Idaho Panhandle tonight, but snow levels will remain above pass levels for motorists traveling. A strong push of cold Arctic air will bring very windy conditions to the Okanogan Valley tonight and Saturday. Cold conditions are forecast for the upcoming work week, with some opportunities for snow. The next big threat looks to come the southeast half of Washington and Idaho later Monday into Tuesday. && Discussion... evening update: the Arctic front is on the move. The main push of colder air is making it into the Cascades and Okanogan, while it remains mild over the southeast half of the forecast area. For example at last report around 8 PM temperatures were in the mid-20s near Oroville, Washington over the northern Okanogan Valley, with north winds sustained between 20 and 30 mph; at the same time Lewiston, Idaho was at 56 degrees, with winds around that area coming out of the southwest at around 15 to 25 mph with gusts to 45 mph. So those winds have been blowing down the Okanogan Valley at a good clip already, so I went ahead and started the Wind Advisory in that area about an hour ago (730 pm). That portion of the Wind Advisory also includes the Waterville Plateau, but those winds should materialize later (after about 09-12z). The other Wind Advisory GOES through midnight (12 am) across the upper Columbia Basin east into the Spokane area and Palouse and l-c valley, as well as the Coeur D'Alene area (which I added at 730 PM to due to some rather strong winds reported at the surface and indicated by radar aloft). Newest model runs support this downward trend. These updates to the Wind Advisory are already on the street. I did increase winds down the Purcell Trench tonight into Saturday, as that increasing northerly gradient develops, but these really don't appear should increase until after 09-12z). The other issue out there is the precipitation. A modest shield of rain continues to Rake the eastern third of Washington and north ID, especially from the Palouse east into the portions of the central Panhandle. All models support this precipitation gradually decreasing from the northwest overnight. On the backside of this, however, will be some some snow threat. The rain changed to snow around the Okanogan Valley, per the ASOS at omk, around 5pm and fell for a couple hours. It wasn't being sampled well by radar and available web cams in the region did not show much. Yet I have no reason to doubt the sensor. So this highlights that some snow threat will be coming on the heels of the cold front and with the cold core of the upper trough. The snow chances will found near the Cascades through the Okanogan the remainder of this evening and above about 5-6kft farther east and south. However later overnight into Saturday snow levels drop toward valley floors. Outside of the mountain the snow is not expected to amount to much: a half inch or so over northeast Washington and north Idaho and maybe an inch to an inch and a half toward the Palouse. More snow is projected about the central Panhandle mountains, where a Snow Advisory remains in place through the day Saturday (4 am to 4 pm). The northwest flow and unstable upper trough will help produce this threat here, while the unstable upper trough will bring the light snow threat across the remainder of eastern Washington and north Idaho. The last thing to mention that some guidance suggests is a possible Puget Sound convergence zone in the westerly flow. It is mainly the NAM/sref which has this suggestion, which wants to show some band of snow developing near the Chelan/Okanogan County border overnight (after 09z) and expanding east across northern Douglas and Lincoln County through Saturday. Typically a band of precipitation associated with the pscz doesn't spread that far east, so I suspect there may be some mix of the incoming upper trough influencing that depiction. /J. Cote' && Aviation... 06z tafs: an Arctic front drops across the Washington and north Idaho tonight, with the trailing upper trough coming through Saturday. Look for areas of rain across the eastern taf sites to turn to showers and dissipate overnight. The showers may mix with or turn to snow before morning. The incoming upper trough will keep the threat of flurries or snow showers alive across the eastern taf sites through Saturday, before the threat wanes at night. The western taf sites (eat/mwh) will see some the potential for a few flurries or a brief snow shower and some increase cloud cover during the day Saturday too, but the threat appear smaller in that region. Winds will remain breezy to windy this evening. The overall speeds are projected to decrease after midnight into Saturday morning, but will still remain gusty through Saturday before abating Saturday night. Note: the visible sensor at eat is out of service so amendments to visible are not scheduled. A replacement sensor is on order. Service may return as early as Saturday, but may not be available until the middle of next week. /J. Cote' && Preliminary point temps/pops...
