Discussion              

A major Arctic air outbreak will blast into the US this week. The core of the frigid air will drop southeastward on Monday from western Canada into Montana/North Dakota and then dive southward to Texas by later in the week. The Arctic air mass will then push to the northeast later Friday with a powerful frontal system at the leading edge of the incoming cold air mass. The powerful Arctic front will likely arrive in the Mid-Atlantic’s I-95 corridor late Friday and its passage could be quite dramatic. Damaging winds are possible late Friday, temperatures will drop sharply, and there can be a quick freeze-up or “flash-freeze” of any lingering wet spots on roadways.  In addition, some snow shower or snow squall activity could develop as the Arctic air pours into the region in a still very unstable atmosphere. Christmas Eve (Saturday) and Christmas Day (Sunday) will be very cold throughout the eastern US with some of the coldest weather conditions for these two days in many years.
