July 27: Evening Storms Approaching!

Thunderstorms continue to push ENE across Pennsylvania towards New Jersey. They’re not moving very fast so estimated impact is still at least a few hours away. Given the current setup and radar observations, it appears that NNJ has a better chance than SNJ. I’m watching the area that I’ve circled below for near-future development. It seems like that line of moisture wants to stream southeastward towards the DC/Baltimore area. If that happens then more of SNJ will likely get in on tonight’s storms. Here’s the playbook diagram:

Harrisburg, PA is currently seeing a decent storm cell. As with any system like this, coastal regions of New Jersey, especially SENJ, have a lesser chance of holding intensity due to marine influence. Dew point temperatures are holding pretty high though and there’s plenty of instability + shear to work with overnight. With that being said, no guards are being let down anywhere in the state of New Jersey. As I always say for the coast, 9 times out of 10 these storms fizzle for you but there’s always that 1 time. Best to be ready for it. The best timing window for NJ impact I can give is 8PM through sunrise. Obviously WNJ will see impacts before ENJ…about 2-3 hours beforehand. I’ll be tracking all night. Be safe! JC
