The Philadelphia region is preparing for an Arctic blast that will bring frigid temperatures and snow showers this weekend. Temperatures are expected to plummet as the Arctic air arrives, making conditions feel below freezing throughout the day. The cold snap will be accompanied by snow showers, particularly on Saturday, as the region experiences two rounds of snow. The weather pattern follows a mild start to the week, with conditions turning blustery and bitterly cold by Thursday night. Residents should prepare for a significant drop in temperatures and potential snowfall as the weekend progresses.
