July 8: Thunderstorm Update
A cold front is moving through PA towards NJ. Ahead of it lies destabilized and unsettled air mass currently responsible for widely scattered showers and thunderstorms. There’s hardly any wind shear so these are mostly instability-driven with tropical surface fuel (dew points above 70). This traditionally results in short pulsing (on radar) storms that pack a quick downpour punch with a few strikes of lightning. All thunderstorms so far have failed to meet severe criteria and are therefore considered just strong thunderstorms. NNJ has seen a bit more precipitation than other parts of NJ due to the training nature of the storms between the I-78 and I-80 area. Some more showers and thunderstorms are currently moving into SNJ (between Philadelphia and Cape May) from the west.
Expect these humid and stormy conditions to last into the overnight hours with more showers and storms possible tomorrow. Be safe! JC
