Kudos to the PDX NWS for at least reporting the potential for snow late Sunday/Monday, nothing from the Seattle NWS: GFS and ECMWF solutions begin to diverge Sun with a complex upper pattern developing. Both models have a low from the Gulf of Alaska dive to CA by Sun afternoon. But the differences are how the models handle the cold air in northwestern Canada. The 00Z ECMWF is pushing the cold air much further to the southwest than the GFS. For example, by 12Z Mon the GFS has 850 mb temps around 0C to -4C over nw Oregon while the ECMWF shows -8C to -10C. If the ECMWF turns out there could be enough cold air pouring off the B.C. coast induce cyclogensis off the WA/OR coast and result in low snow levels, possibly below 1000` ft. But that is just one model run. Current forecast is about a blend of the two. /mh Cyclogenesis!

Ignorance is bliss. Keep on believing that thought!

For those who have not read this yet, the attached three month forecast from Pete Parsons is intriguing. http://www.oregon.gov/ODA/programs/NaturalResources/Documents/Weather/dlongrange.pdf My apologies if this does not link automatically.
