The U.S. is bracing for a series of back-to-back winter storms that could blanket the Northeast, impacting major cities including New York, Boston, and Washington, D.C. This weekend, areas of Massachusetts are expecting plowable snowfall, with forecasts suggesting accumulations of 3-6 inches. Residents should prepare for a combination of rain and snow, with significant snowfall predicted from Saturday into Sunday. A winter storm watch has been issued for the I-95 corridor, and travel warnings are in effect across 15 states due to the severe weather conditions. Following the storm, a polar vortex is expected to usher in the coldest temperatures of the season, with wind chills plummeting significantly. Meteorologists are tracking these winter systems, and updates will be crucial for those planning to travel during this busy holiday weekend.
