FOX 29 Weather Authority: 7-Day Forecast (Thursday update)

FOX 29's Kathy Orr has the latest on the plummeting temperatures and storm that could bring significant snow to the region starting Sunday.

PHILADELPHIA - Temperatures will continue to plummet over the next few days ahead of a developing nor'easter that could bring hours of significant snow to the area.

Temps will only make it to a forecasted high of 27 in Philadelphia and surrounding counties Friday.

Gusting winds will continue and make the wind chill factor even harsher. Feel-like temperatures will be in the single digits and below zero in some spots.

Snow is expected to move in Sunday afternoon and last all day Monday before pulling offshore by Tuesday.

Philadelphia and the northwest suburbs could see significant snow. Some parts could see anywhere from 6 inches to a foot of snow, according to the Euro model. The GFS is predicting lower totals. Down the shore will only see wind and rain but interior sections of South Jersey should expect all snow for the balance of this event.

FOX 29’s Scott Williams says the track and temperature will be key for this long-duration storm.
