Philadelphia, Pa. weather: Rain, flooding risks Sunday night
PHILADELPHIA (CBS) -- It's the calm before Saturday night, as a storm headed to the Philadelphia region Sunday into Monday aims to bring flooding and wind risks, with the entire area under a slight risk for flash flooding Sunday.
For now, overnight Saturday into Sunday will bring light winds, increasing clouds and a chance for some patchy fog toward daylight.
It's best to get any errands done early Sunday, as the rain rolls in during the afternoon and lasts into Monday morning. The early commute on Monday will not only be terrible, but potentially dangerous. If you can work from home, Monday is the day to do it.
Sunday and Monday are NEXT Weather Alert days due to this storm.
By Sunday morning, the center of a strengthening low-pressure system will be near the coast of South Carolina, but by lunchtime light showers ahead of the approaching storm system will begin to move into the Philadelphia area.
We'll see spotty afternoon showers before widespread rain develops in the evening.
Most regions will see the heaviest rainfall from 11 p.m. Sunday to 5 a.m. Monday, but rain will continue through the Monday morning commute. In South Jersey and especially at the Shore, a second band of heavy rain will cross over Monday morning.
A wind advisory is in effect at the Shore from 6 p.m. Sunday to 6 p.m. Monday with winds of 20-40 mph, and a few gusts to over 50 mph.
This finally tapers off between 10 a.m. and 1 p.m. on Monday.
Rain totals between one and three inches are possible, but some pockets near the Shore could see three to four inches of rain. A lot of this rain will fall while you're sleeping.
This storm should last longer than last Sunday's storm.
Temperatures take a huge dive Monday after the storm moves out — low enough that we could see scattered snow showers — with the greatest chances in the Lehigh Valley and Poconos.
