Discussion              

An active weather pattern will continue through the week across much of the nation.  Multiple low pressure systems will form in a boundary zone region between very cold air sitting across the northwestern states/southwestern Canada and very mild air draped across much of the southern US.  The next in a series of low pressure systems will generate some rain around here later this evening and then another one later tomorrow into early Thursday. A stronger storm early this New Year’s Day weekend could have a big impact on a large part of the nation with mild, rainy conditions likely around here, a possible severe weather outbreak in the Tennessee/Mississippi Valleys, and accumulating snow in the Upper Midwest.  A second storm could follow from later Sunday into Monday and - given the potential of colder air filtering into the Mid-Atlantic from the northwest - it is a threat that needs to be monitored in coming days.
