Thanksgiving Weekend Weather (Wed-Sun)

The black and white RGEM looks like it may go close to or a hair SE of the BM. Very close to it.

The RGEM was my bread and butter for ptype last winter, I literally started using it for every storm to figure out ptypes and changeover times, it was right almost every event and its done well so far this year on Midwest events...it has very bad 06 and 18z runs, on the level that the US models used to have years ago so I don't use those often but I will probably rely on it heavily starting 12Z tomorrow for NYC/PHL/BOS

Basically your favorite. It will lead to mesoscale areas of vertical and downward motion. They won't be stationary but will favor setting up in the same pattern. So localized maxes or mins in QPF are possible.

 

The pressure perturbations they produce can also lead to enhancing local wind fields too. Especially in the "warm" sector this could lead to a brief mixed layer enough to bring down some of the LLJ.

 

Thanks.

It's a good model.

BOX is pretty underwhelming with the forecast in GC.  I guess to moderates equal 8-10 (their map).  Better than bare ground though.

 

Wednesday Snow. Moderate snow accumulation. Much colder. Near steady temperature in the lower 30s. North winds 5 to 10 mph. Chance of snow 80 percent.

 

Wednesday Night Snow likely. Additional moderate snow accumulation possible. Lows in the mid 20s. North winds 10 to 15 mph. Chance of snow 70 percent.

Yeah 8-10" of snow is pretty underwhelming on 11/26

Dude I'll swap with you in a heartbeat, lol.  What's underwhelming about it?  What were you looking for?

 

I think their snowfall works something like this...Light is 1-3, moderate is 4-7" and heavy is 8"+.  Too bad you only get two periods of 4-7" ;)
