Increased Tendency Of Humidity, More Showers Around

A humidity front will push northeast through the region today, bringing an increased risk of showers and soaking storms to the Delaware Valley. There will be a couple of opportunities for rain -- the first through midday and the early afternoon as the humidity front slides slowly northeast through the region. Some of the showers and storms will produce heavy rains during the course of the day, with the best chances of this as of now modeled to be north and west of I-95.

A second, and perhaps more notorious shot of moisture will work through Ohio along a disturbance that's pushing east. That disturbance moves through tonight and tomorrow morning with more rain and thunder, perhaps with a more widespread heavy rainfall risk for the Delaware Valley and points north than what happens today.  Modeling has waffled a bit on placement of tonight's storms but earlier runs had given us a second shot of heavier thunder late tonight. We'll keep an eye on it and update the blog and our social media with info as needed.

Some sunshine is possible in spots, especially south of the city later in the day. Otherwise, more clouds than sun is expected. With higher humidity levels in place, it will certainly feel more typical of August. Temperatures by day's end will range from the 70's north to the lower 80's south of the city, with Philadelphia projected to be around 80 by day's end.
