A brutal arctic blast is sweeping across the Midwest and heading towards the Northeast, bringing dangerously cold temperatures and wind chills as low as -20 degrees in parts of Massachusetts, Rhode Island, and Connecticut. The upcoming days will feature ALERT DAYS for bitter cold, with significant snowfall expected this weekend amid cold weather advisories. Residents are advised to prepare for severe conditions, including sub-zero wind chills and a potential winter storm, as the coldest air of the winter arrives. The polar vortex is contributing to this severe weather pattern, promising persistent arctic air and possible snow accumulation throughout the week.
