Stay safe, residents of the eastern seaboard!

A powerful 950 millibar nor'easter cyclone will be tracking towards Maine through tomorrow. It will cause 1 to 2 feet of snowfall and damaging northeasterly winds over 65mph, leading to power outages and severe blizzard conditions!

Additionally, the storm will combine with a building arctic surge of cold temperatures to result in another wave of arctic cold, with temperatures down to -25 degrees and wind chills to below -45 degrees across the Great Lakes and northeast as far southeast into the Ohio Valley and Mid-Atlantic coast.

People from the central Plains through the Midwest/Northeast will have to prepare for the likelihood of a major winter storm between Friday through Sunday of this weekend.

With arctic high pressure and cold air mass north of the low pressure system, and ample moisture from the Gulf of Mexico overrunning this cold air mass, the synoptic conditions will be favorable for both a major snowstorm and a significant mixed-precipitation event, including the possibility of an ice storm.

So, winter storm watches may be required.
