Major Winter Weather Pattern the Next Two Weeks

The weather leading up to the holidays will be one of the more extreme in regards to snow and ice. I think over three-quarters of the country will have snow prior to the holidays, and it's not out of the question that at least 20+ states has snow on the ground for Christmas. Most likely, the wintry pattern will back off some after the holidays.

Initially, the coldest and most dangerous air mass will stay in the northern Plains where highs may not get over 20 degrees for at least 10 days. Some of the cold air will split across the Great Lakes and into the Northeast which will set the stage for at least two snow events between Dec. 13 and 17 of the month. The NAO is going negative which means to watch the East Coast for development and possible snow.

The ice storm from Texas to Kentucky is going to be very nasty with up to an inch of ice accumulation. That means extended power outages for parts of Arkansas. Keep in mind, the snow and ice will occur with two events: one Thursday into Friday night and another Saturday night into Monday. The same areas shown on the map will get snow and ice with both events.
