Kind of the same as here. We will need some form of north or northeasterly component to get the real goods. I do know strong cold fronts will give Leavenworth the goods, but doubt that happens in this pattern. At least initially. Our normal temps in late November and early December are generally cold enough for snow, though just barely (until you get to mid December). We don't want storms coming in from the NW, we get heavily shadowed. We would want the low to come inland to the south after having spent some time over the ocean and then we get good upslope enhancement. Certainly it would be cold enough for snow, at least for the 2nd trough. We had 3.5 inches of snow Tuesday, and we have had snow on the ground since the 6th. That is pretty early for snow to last this long. 3 Link to comment Share on other sites More sharing options...

Dave Posted November 24, 2022 Report Share Posted November 24, 2022 I'm still snow covered but it's pretty sloppy. I have many slushy dog turds to deal with tomorrow. Predictably it looks like it might snow on the day I leave Bend. I knew this would happen the moment I planned the trip. 1 Link to comment Share on other sites More sharing options...

snow_wizard Posted November 24, 2022 Report Share Posted November 24, 2022 One thing to remember is blasts from the north are much more likely to produce snow for Seattle than backdoor ones. Mins temps are usually a lot colder too, because we don't have east winds to deal with. Right now this thing looks top tier for this early in the season. That is other than events like 1955 and 1985. 3 1 1 Death To Warm Anomalies!

And that usually comes with a low to the south. The E/NE winds help with precip rates and helps with cold air damming. I don't get as excited by arctic blasts as most do because they are sometimes too dry for significant snow. Give me normal temps and average to above average precip and I get a lot of snow. 1 Link to comment Share on other sites More sharing options...

TacomaWx Posted November 24, 2022 Report Share Posted November 24, 2022 GEM and gfs are a bit different but great scenarios either way. The first shot of cold air coming early next week on the Euro,Gfs and Cmc is showing 850mb temps in the -8C to -10C range. Pretty decent warning shot if the models are to be believed past early next week showing an even colder shot potentially. 4 1 Link to comment Share on other sites More sharing options...
