Another massive cold wave headed for Eastern US next week to put temperature 20 degrees below normal

Senior WeatherBell Meteorologist Joe Bastardi commented:

I am 58.. never seen anything close to this for late March.

and

[The] pattern next week has as much extreme potential for the time of the year as I can find. Coldest opening to calender spring in 50 yrs at least.

Weather forecast models such as the ECMWF and NCEP, both of which have had good track records this year in identifying polar vortex outbreaks in advance, are now forecasting a massive cold blast for the beginning of spring. See maps:

Dr. Ryan Maue commented on this forecast from ECMWF:

ECMWF 12z (WMO-Essential) 850-hPa temperature + wind streams. Final 10-day outcome after 2nd Arctic blast. Brutal.

He added:

Canadian ensemble system looks like other guidance at 7-days as well. This cake is baked. Arctic blast to end March … If Lake Michigan can open up a bit, then this cold could drop enormous amounts of Lake Effect snow on Lower Peninsula of Michigan.
