First significant rain since mid-September arrives in Philadelphia

We haven't had really significant rainfall since the middle of September. But the next couple of days will be warm, humid and feeling very tropical.

FOX 29 Meteorologist Scott Wiliams says we're watching the remnant moisture associated with Nate move in our direction, and it looks like on average we'll get about an inch of rain today into early Tuesday.

That swirl on radar is now Tropical Storm Nate. It made two landfalls, the first around the mouth of the Mississippi River and then second around Biloxi, Mississippi.

That moisture will kind of stream into our area, beginning with some spotty showers Sunday morning.

By 1 p.m., it's mostly cloudy, warm, humid, and there could be few spotty shares around at Lincoln Financial Field, so keep that in mind. You might want to grab the poncho.

On Monday morning, that wave of very heavy rainfall starts to move in through the afternoon and evening, and then the system is out of here early on Tuesday.

Temperatures were in the low-to-mid-70s already Sunday, well above average for this time of year. Winds are coming in out of the south at 10 to 15 miles per hour, pumping in all of that moisture, so that's why it feels very humid and tropical.

Our Weather Authority seven-day forecast shows the bulk of the heaviest rainfall Monday into the afternoon and evening, then gradual clearing, warming up into the low 80s Tuesday. Things are cooler by Thursday, when we're in the upper 60s.

But then we warm right back up for next weekend.
