Satellite shows one system heading out across New England. Blue in Texas is next system taking the southern route...and may provide some spotty light precip. for Northeast this Sunday. System off west coast could be the troublemaker for Christmas eve into Christmas Day.
Canadian Model for Christmas eve - One low offshore and another over Great Lakes. System offshore will bring rain to Northeast...Gt. Lks storm..snow there. Low coming out of Rockies will bring snow there.
Above - Euro model....wanting to bring near-blizzard weather from upper Midwest thru Great Lakes & Ohio Valley....while wind and rain hit the east coast.
