Severe Storm Threat
A decent chance of severe storms exists for the northern Mid-Atlantic region today, including NJ, PA, MD, and DE. Storms will start to form out in western and central PA around 2pm give or take an hour or so. These storms will have the highest tornado threat as they push eastward into eastern PA because of the discrete nature of these storms. They will then congeal into a squall line. This line will press east, producing damaging winds. There will be an isolated tornado threat associated with the bookend vortex on the squall line. Otherwise it is mainly a damaging wind and flood threat. The storms will clear the coast around 9pm or so. Make sure you have a way to get warnings and keep your eye to the sky.
