Notice the NAO is going negative next week; in fact, we have been in a negative NAO most of the summer. Some studies have shown that a negative NAO during the summer means heat in the Northeast, while a negative NAO in the winter means colder, stormy weather. So one can surmise that as the jet starts to migrate south in September that a negative NAO would mean stormy weather for the Northeast which looks to be the case next week.
The system coming out of Texas and the Gulf Coast will bring a lot of rain north late in the weekend and early next week. You can see on the GFS model total rainfall that some areas can pick up 1-3 inches of rain which may cause some minor flooding problems.
Also, the pattern across the Great Lakes and Northeast will feature several pushes of chilly air the next 14 days. I would not be surprise to see snowflakes over the Upper Peninsula of Michigan in the cold pushes.
Blizzard continues to rage across New England. More snow is coming with two more storms.
The blizzard will hit tonight and last into Tuesday. This will be an extreme storm for New England.
Major snowstorm starts with workweek as clipper explodes off the coast. It may become a blizzard for New England and NYC.
Two shots of snow are coming as a storm comes north followed by clipper snows Sunday into Monday.
Two snowstorms will affect the East over the next 5 days.
Clipper snows today could be heavy in places. Next storm will bring snow to the I-95 corridor.
