RE: Thurs-Fri event
The 12z GEFS is advisory level snow/ice N&W of I-95. It's "contaminated" by a few inland running coastal lows that go into Lancaster/Lehigh Valley. If we get rid of those, it's probably a solid event.
Behind the chances for this week, we turn into a legit -NAO/-AO and neutral to slightly +PNA, with favorable EPO. No two ways about, we are looking decent.
Old forecasting rule was 3 to 4 isobars ahead of the storm it meant the Gulf was open for business. Looks like health blocking in Canada and the Atlantic at 500mb at HR240 ahead of the storm. That's nice.
