Midwest Christmas Blizzard...

The storm that brought snow to Texas (giving Dallas its first white Christmas since 1920) and tornadoes to the Gulf coast is now producing a blizzard in the upper Midwest for Christmas Day. Up to 20 inches of snow is forecast. This storm will produce rain in the NYC area Christmas night and on Saturday. Behind the storm, very cold air will again invade the upper Midwest and the Northeast. The maps above are the 18 hour NAM forecasts for the surface and 500 mb levels. A huge upper-level low can be see circulating in the Midwest at 500 mb (approximately 18,000 ft.)
