Early April In Pa.: Polar Vortex, Snow Possible, Forecasters Predict

April is going to get of to a cold start — complete with a Polar vortex and the possibility of snow — according to forecasters.

The polar vortex is expected to take a southward plunge, sending arctic air and even the potential for snow toward the northeastern United States, including Pennsylvania, during the first week of April, forecasters with AccuWeather predict.

The northern part of the mid-Atlantic is one area that will get a hefty dose of the cold air and temperatures will be "unseasonably cold," according to AccuWeather.

"Temperatures in the Northeast will be 10-20 degrees Fahrenheit below normal, which will be the largest negative anomalies since Valentines Day," AccuWeather Meteorologist Joe Lundberg said. "When the wind is factored in, it will feel a whopping 40-60 degrees colder than it will late this week."

Normal high temperatures for the region are typically in the upper 50s to 60s.

But next week won't be normal — the high temperature Sunday, Monday and Tuesday will be in the 40s, according to the National Weather Service. Low temperatures will be in the 20s Sunday, according to the forecast.

Snow showers could accompany the frigid weather, especially along the I-95 corridor, according to predictions by AccuWeather.

The National Weather Service also has a chance of snow in its 7-day forecast. The NWS says there's a chance of snow showers Monday and Tuesday.
