Bring it on baby. Lets hope this lasts another 6 months and then winter starts over.

Arctic Oscillation is predicted to be about as negative as it can get over the next few days..This forces arctic air much farther south

If only it could be like this in July... but I bet it'll be 95 degrees and sunny instead.

LOL. True, especially being in an era where its so easy to get well above normal. Probably touch 90s in May..

But latest GFS says wamth?... not just yet..
11-15 day 850mb anomalies. March 28th to April 1st.

We'd fine with a cool July*.

a cool July here would probably have the temperatures of Northern Ireland's warmer month ever

How much does the Arctic get warmer in turn?

[Cambium]

After tomorrow night/Tuesday snowstorm mvoes out, looks like more snow Thursday for NJ, CT, RI, MA again. Light stuff though.



But Next snowstorm in the making for end of month? We'll see. Wow. Buckle Up!

EuroEPS control has a 976mb beast. 850s below freezing all the way off the coast. Goes OTS after this.



GFS agrees on a storm in this time frame. IN fact shows blizzard conditions in northern Mid Atlantic area here.

Just look how deep that trough is digging (blue line). Thats a red flag for anyone expecting spring... and a bell for those expecting winter storms. Thats perfect setup for east coast storms. When it digs that far south..

It looks like the arctic air machine is going to kick into high gear for the rest of the month. The models continue to trend colder, with the latest GFS showing well below normal conditions for the Eastern U.S. through Easter. Quite a few snowstorms are indicated as well. I ran the numbers and some parts of the Southeast are already well below normal for March temperatures, and if the latest (and coldest) GFS model data is correct with regards to temperatures, some locations could average 12F below normal for monthly highs - the coldest since 1960. Also, there is an outside chance of March being both the coldest and the snowiest month of the winter for parts of the Southeast. That's just wild .

Interestingly, those sort of cold departures are comparable or somewhat greater than the warm departures they had last year. The pattern on that model run was a colder version of what most other models are showing - well below normal in the East, and near or slightly below normal in the West. This sort of pattern is being produced by the strongly negative AO and a moderately negative PNA, which tends to produce a very cold East/normal West pattern (Dec 2010 is a prime specimen of that).

Just imagine if those sort of cold departures had occurred in January. The United States would be in the same position Eurasia was in (and still is in) this winter.
