snow_wizard Posted November 16, 2019 Report Share Posted November 16, 2019 If we do end up with a cold snap to finish out the month like some GFS runs and ensemble members are showing that would make this late Oct through Nov period a dead ringer for 1936.

snow_wizard Posted November 16, 2019 Report Share Posted November 16, 2019 Well over an inch for places up north of seattle from that convergence. Some places approaching two inches.

snow_wizard Posted November 16, 2019 Report Share Posted November 16, 2019 Here is my prediction for the next couple of weeks. First the trough early next week will be enough to get our frosty nights back. From there the entire dry period following should be on the chilly side due to inversions and northerly surface pressure gradients After that (8 to 11 day period) we will see the blocking retrograde, but still be too far east to be all that exciting for us. About 4 to 6 days later there will be another retrogression step that will bring us something notably chilly in early December. That's the way things look at this moment at least. It's still possible the retrogression around day 10 could nail us with cold, but I think we will have to wait until the next step. 1 Quote Death To Warm Anomalies!

But technically... just a switch to SW flow would clear it out. The amount of rain was pretty much meaningless to that process. And our water supply will be determined by mountain snow this winter and next spring... not rainfall in Seattle.

That hasn’t been the case. Even after the front moved through this morning, it got windy so that was the main factor in cleaning out the air. I’ll take that any day if it’s not gonna rain. Also, the one thing that surprises me the most with the current pattern is we don’t see much inversion. Typically this time of year, if it doesn’t rain we’d be socked in with a nasty inversion with fog capable lasting whole day. Quote Link to comment Share on other sites More sharing options...
