For example at hour 126, NYC is sitting in the lower to mid 20's at the surface. That’s a quick heavy thump followed by a dangerous icing depiction..... ouch!!!

NJwx85 Posted January 15, 2019 Share Posted January 15, 2019 No redevelopment this run. If you track the primary, it runs from Western PA, to Albany to the Gulf of Maine in 12 hours. Link to comment Share on other sites More sharing options...

NJwx85 Posted January 15, 2019 Share Posted January 15, 2019 While the GFS thermal profiles have a known warm bias, it's going to flip all areas to plain rain if the surface low takes a track into upstate NY. Link to comment Share on other sites More sharing options...

NJwx85 Posted January 15, 2019 Share Posted January 15, 2019 The key to forcing the redevelopment would be stronger influence from the high pressure to the North. Again, the GFS doesn't have a ton of skill when it comes to CAD setups. The Euro though isn't much different so the GFS has more weight. The strong CAD would at least prevent the surface from torching and we would hold onto snow for a few more hours. It's a little hard to see on this graphic but the ICON shows the CAD signature. The signature is with the sagging of the isobars to the Southwest over NY, PA, NJ and New England. Think of that as the cold air essentially pressing down from the high.

Its prediction may be wrong, but this isn't one of those cases where the surface low track is clearly not in harmony with the model's own synoptic depiction. The trough axis is well west... you can see how cyclogensis is rooted to the divergent jet streak region. Link to comment Share on other sites More sharing options...
