TT-SEA Posted December 18, 2016 Report Share Posted December 18, 2016 Funky pattern on the Euro. 12Z ECMWF is perfection at the surface. Good snow on Friday into Christmas Eve and then it stays cold with no precip from Saturday night through Tuesday... then a little overrunning snow on Tuesday night.

Parksvillewx Posted December 18, 2016 Report Share Posted December 18, 2016 Just occasional flurries here this morning. 1/4" accumulation.

TT-SEA Posted December 18, 2016 Report Share Posted December 18, 2016 Jim takes the day off and all hell breaks loose. ECMWF has trended much better for cold... but I am thinking its not the best pattern for his location to get snow on the 12Z ECMWF with a c-zone in the typical spot up here and all the way up to Randy. He would also warm up fast on Christmas morning just like the big snow event for many last Friday if the 12Z GFS solution verified. Seems like every pattern is much better for snow all around the SW King County and Pierce County areas. Lets hope the ECMWF is right because then at least it would be cold for everyone. The 12Z GFS would result in a rainy Christmas Day for some and wonderfully snowy for others... you think his hissy fit was bad last week?

snow_wizard Posted December 18, 2016 Report Share Posted December 18, 2016 Incredible improvement in a number of time fames / models today. 1. ECMWF and GFS both show it cold enough for snow for Seattle into tomorrow morning 2. Both models show lowland snow around Christmas 3. ECMWF shows 850s dropping to -9 between Christmas and New Years with some lowland snow 4. CFS (4 run composite) now shows a major cold snap between Christmas and New Years. Was not showing that yesterday 5. ECMWF and GFS both show PNA at -3 around Christmas It should be noted the CFS has outperformed the GFS in predicting near term cold waves on multiple occasions in the past that I have seen.

Heavy Snow Posted December 18, 2016 Report Share Posted December 18, 2016 The updated run of the 12z EURO shows a modified Arctic Blast arrive on Christmas Day. Unfortunately it shows a system head into California the next day. If it heads into the PNW it would give us Snow. It's still a long ways away and we just saw this past week how originally the system that brought many of us Snow was headed to California but at the last minute decided to head up here. http://maps1.pivotalweather.com/maps/models/ecmwf/2016121812/168/850t.na.pnghttp://maps1.pivotalweather.com/maps/models/ecmwf/2016121812/192/850t.na.pnghttp://maps1.pivotalweather.com/maps/models/ecmwf/2016121812/192/sfcmslp.na.png 1 Quote Link to comment Share on other sites More sharing options...
