Some parts of our region have picked up over three inches of rain so far today from scattered heavy thunderstorms. The main axis has been from Mays Landing northwest through the Philly metro north through Doylestown and Easton. Parts of the western burbs have seen little more than trace amounts of rain so far today and some at the Shore have had a bit more sun than clouds, avoiding showers in the process.
However, in a few spots, heavy rain has fallen. Some of the totals through 3:30 PM are listed below. The Airport has picked up just shy of two inches. Some of the totals, such as Drexel Hill and Pennsauken, are likely a bit low but they were reported earlier in the afternoon.
With humidity still in place, the night is not without the risk for at least some scattered thunder. A frontal boundary is to our west and has triggered thunderstorm development across Upstate New York and Western Pennsylvania, with enough instability to our north and northwest to warrant a Severe Thunderstorm Watch north of I-80. While we're not under a watch here, the fact that there's a boundary out to our west does warrant mentioning scattered storms. It does look like the odds of the city getting in on anything over the next couple of hours is pretty low -- looking back to our west, there isn't much in the way of thunderstorms out there until we get west of State College. However, there is activity across the Lehigh Valley that's pushing southeast. That could conceivably work down through Bucks and Mercer Counties later on this evening.
The front pushes through early in the morning...while we should be humid through the night, you'll feel relief work on in through the course of Tuesday. Unfortunately, with one more night of humidity the risk of thunderstorms continues in parts of the region.
