Philadelphia is set to experience a significant weather transition this week. The week begins with a freeze warning on Tuesday morning, urging residents to protect sensitive plants and outdoor plumbing from the cold. However, this cold snap is expected to be short-lived, as temperatures are forecasted to rise dramatically by Wednesday. Meteorologist Kate Bilo from NEXT Weather reports that the region will see rain showers on Wednesday, marking a shift to warmer conditions. This change represents a stark contrast to the current cold spell, bringing both precipitation and higher temperatures as the week progresses.
