tombo82685 Posted November 27, 2018 Report Share Posted November 27, 2018 EPS are starting to show to potential periods to watch for. First one is around the 5th which looks to be an anafrontal type wave along the boundary coming east. Think that one has a better chance of wet rather than white. Se ridge is going to put up a fight so it may take a little time to get the cold to the coast, but could set up a third wave after the 5th. They also have the period between the 8th and 10th as potential, this one seems better as the cold air will already be in place. Quote Link to comment Share on other sites More sharing options...

Gefs have the 8th-10th as a primary west with coastal transfer too far north in NE, similar to most recent storm. Same on EPS or do some of the members show the primary below us?

Could get something at beginning or end of cold snap. 06 fv3 below. Will take a while to sort out the details. Quote Link to comment Share on other sites More sharing options...

Consistent with last nights runs. Could be a better threat for I95, MA and even the SE, if the convergence and STJ pan out. Quote Link to comment Share on other sites More sharing options...

It gets flattened out pretty good as it does so, but def a milder look from last night. Quote Link to comment Share on other sites More sharing options...
tombo82685 Posted November 27, 2018 Report Share Posted November 27, 2018 Looking at the eps I would say there are three periods of interest before the pattern goes down the toilet. first would be 5-6th time frame for a possible follow up wave if the front gets hung up around the coast. Second would be around the 8th for a possible storm coming out of the south that could have a primary to the west then coastal take over. Third would be around the 11th with the changing of the pattern as the warmer air starts to come east and attacks the cold. Quote Link to comment Share on other sites More sharing options...
irishbri74 Posted November 28, 2018 Report Share Posted November 28, 2018 5th and 9th timeframe on 18z GEFS: Quote Link to comment Share on other sites More sharing options...
susqushawn Posted November 28, 2018 Report Share Posted November 28, 2018 Definite potential 12/8 with this look. Closed low ejecting out of SW, transient confluence in place for high pressure, +PNA, cold wedge. Comes down to timing of any phase, confluence is mobile so CAD could erode etc and the details will continue to bounce around. Nice to see potential Quote Link to comment Share on other sites More sharing options...
Chubbs Posted November 28, 2018 Report Share Posted November 28, 2018 Nice trends last night. Here are the changes for the euro a week out. A couple of obs: 1) plenty of changes in wave spacing/location in E NA and WC ridging so still quite uncertain, 2) Big 50/50 popped on last nights run, 3) Much stronger with wave for Dec 8 system nearing Ca. 2 Quote Link to comment Share on other sites More sharing options...
Chubbs Posted November 28, 2018 Report Share Posted November 28, 2018 00z 10-day GEFS, strong signal for a GOM system. Likely to be a snowstorm for somebody in the east. Quote Link to comment Share on other sites More sharing options...
tombo82685 Posted November 28, 2018 Report Share Posted November 28, 2018 Would say on the eps, the dec 8-10th period has a better signal. The dec 5 threat did bump up a little last night but not as strong as the dec 8-10th period. 5/6th 8/9 Quote Link to comment Share on other sites More sharing options...
Heisenberg Posted November 28, 2018 Report Share Posted November 28, 2018 You guys will prob laugh at this, but the dec 8-10th period reminds me of feb 5 2010 with the way the GFS has energy coming out of the Southwest into a wall of HP & CAD. Driving or I’d post the image similarities i see. Quote Link to comment Share on other sites More sharing options...

Driving or I’d post the image similarities i see. it def has the best shot of the two right now. The airmass is much better in front of it compared to the dec 5th one which is more timing and proximity of the front Quote Link to comment Share on other sites More sharing options...

Heisenberg Posted November 28, 2018 Report Share Posted November 28, 2018 Yeah, way out there, but that Dec 8-10 system has all the ingredients. Great jet configuration, you got the the 300mb jet screaming out of the southwest with one racing across the NE which locks in the cold HP Quote Link to comment Share on other sites More sharing options...
