Area Forecast Discussion National Weather Service Spokane WA 436 PM PST Fri Dec 13 2019

SYNOPSIS. Snow showers are expected through the weekend mainly over the mountains. Light to moderate snow accumulations will be possible over southeast Washington and the Camas Prairie tonight. Monday and Tuesday are likely to be dry with a return to unsettled weather possible for the middle to end of next week.

DISCUSSION. Late afternoon update: after examination of high-resolution models and radar, as well as observations across the region, I decided to increase PoPs across the region. First near the Cascades the incoming disturbance and the strong westerly flow may help to push some of the Cascade crest showers off the crest toward the Waterville Plateau. I'm not thinking much will fall, but the threat of snow showers is there.

I also increased PoP across the northern mountains and going into the overnight into early Saturday across the Columbia Basin and southeast. With the incoming disturbance and remnants of yesterday's boundary, combined with the unstable atmosphere on the north side of the jet some showers are possible. Again limited threat, but it can't be ruled out. The Cascade mountains and the Central Panhandle through southeastern CWA (areas south of I-90) continue to have the best threat of more than inch of snow, including up to 5 on the Camas Prairie. Elsewhere accumulations should be less than an inch and in most cases a dusting to less half an inch if anything.

I will reassess things as new model guidance comes in over the next few hours too. /Cote'

AVIATION. 00Z TAFS: The area remains in a west-northwest flow with disturbances caught up in that flow. Areas of low clouds will slosh about the Basin, bringing a mix of VFR to IFR conditions around TAF sites early this evening. The low clouds and fog are expected to expand later this evening into Saturday morning, with more persistent MVFR/IFR conditions. A risk for -sn possibly mixed with -ra will develop around the region during that time frame too. The best threat will be found over COE/PUW. Chances wane in the afternoon. /Cote'

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
