After a week of severe thunderstorms, heavy winds, and near-record high temperatures in eastern Pennsylvania, a cold front is sweeping through the region, bringing rain that will transition to snow by Thursday evening. While significant accumulation is not currently expected, the rapid temperature drop and strong winds could make for slippery travel conditions, especially during the morning commute.

Why it matters

The sudden shift in weather patterns is being attributed to a break in the polar vortex, which has occurred numerous times this winter and could happen again in early April. This unpredictable weather is disruptive to residents and can impact travel, school closures, and other daily activities.

The details

The rain will continue throughout Wednesday, with temperatures steadily falling to around 35 degrees by 5 p.m. The precipitation will then transition to snow, with steady winds up to 20 mph and gusts up to 40 mph in more outlying areas. While significant accumulation is not expected, the combination of snow, wind, and cooling temperatures could make for hazardous travel conditions, especially during the morning commute on Thursday.
