A few notes:  ECMWF sub seasonal ensembles via ecmwf.int.  imo tend to  be too dry here in the northeast and deny the shorter range global ensemble expectations.  Be alert for that.  Huge error this past weekend - see attached ecmwf.int prediction the 19th, and you know what happened!

Also fwiw:  via ECMWF.int. Week 3-4,  2m temp departures, I suspect are related to snow cover... see the repeated weekly prediction of colder than normal-here ne USA and OH Valley, and where the snow depth is this morning (and the southern boundary likely to be close to that 16 days - Valentines Day)  from now.

 GFS MOS (MEX). I have no access ecmwf mos. GFS MOS is missing too warm on nighttime lows NYC CP... this I think will be a factor on getting much colder than morning MEX MINS this weekend as the BL wind tends to go northernly---easier access CP.   I still try for 2-3F above zero. This also portends the power of the weekend storm. Occasionally prior to these huge northeast snowstorms, it sets up with MB T cold prior to, like this past weekend, and what I think is likely this weekend (excepting unknown nw fringe of snowfall). If you read Weather Wise (Ludlum et al) issues for the big snowstorms including Kennedy Inaugural Jan 1961... big time cold prior to.
