We continue to watch not one but 2 snow makers ahead of the first wave of arctic cold into the East.

The EC storm track appears to be slightly inland as it heads up the coast and therefore rainfall may be more substantial than previously thought for the Big Cities. There also appears to be less cold air available but this doesn’t mean there won’t be snow from DC to Boston. It just means there may be less.

This system could still bring 1-3, locally 5 inches to the I-95 corridor from DC to Boston on the colder backside.

Another clipper follows the weekend storm and this marks the leading edge of wave 1 of arctic air driving into the East. This may bring more snow than the weekend system. It’s all down the track!

ECMWF snow cover by day 5 following coastal storm and clipper.

This will determine how cold the Big Cities get next week.

I showed you the crazy temps the EPS control was showing next week in yesterday’s post, well here’s the deterministic. 0-5F for NYC?

The very cold days early/mid next week appears to be just the opener of a very cold 10-15 day period in which there may be 2-3 waves of severe, perhaps extreme cold.

CFSv2 sees this unfolding frigid pattern.

Check out the ENSO-MJO index analog package for the upcoming 30 day period.

Looks a lot like the JMA has with a frigid Feb!
