Any of our Northeastern readers know the weather term nor'easter very well. It's a powerful low-pressure system that rapidly strengthens off the East Coast and produces heavy snow, damaging winds, and coastal flooding. 

NBC Boston's meteorologist Pete Bouchard tweeted Monday morning, "I wouldn't be doing my job if I disregarded the storm threat for Saturday."

"So here's my due diligence: There's a good possibility of a nor'easter with significant snow starting Friday night and going through Saturday. 

NBC/MSNBC's meteorologist Bill Karins said three long-range forecast models show a winter storm near New England on Saturday. He said forecasting snow totals or even pointing out high impact areas is unknown at the moment, "but confidence growing for a significant weather event including heavy snow, high winds & coastal flooding."
