'2-Wave' Storm Could Now Mean 6 Inches Of Snow For Philly Area

Will winter go out with a bang? Forecasters are predicting a "two-wave" storm this week, which could leave six inches of snow behind across the Philadelphia region. The updated forecast was provided by the National Weather Service early Monday, and won't make you happy if you're anxiously awaiting spring. (Who isn't?)

The storm is expected to move in late Monday into Tuesday and could come in two waves, bringing another round of snow Wednesday, the NWS said. A total of six inches could be left behind when it's all over.

Buckle up, because the NWS is anticipating it will be a "long duration" event.

Here is the map of snowfall predictions:

The NWS says while the impacts from the storm are still uncertain, "there is growing concern for more substantial snow and impacts," as of Monday morning. Those impacts include travel hazards, coastal flooding and more power outages.

AccuWeather is also predicting a similar forecast for the week, saying a pair of storms are expected to deliver two rounds of "potentially disruptive" snow to the northeastern United States. The first storm will whiten parts of the mid-Atlantic Monday night into Tuesday, meteorologists from AccuWeather said.

"On its heels, a second storm can spread snow from the upper Ohio Valley and southern Appalachians to the Interstate 95 corridor of the Northeast from Tuesday night into Wednesday night."
