Severe T-Storm Line




11:52 p.m. UPDATE:

We have been really getting hit tonight with some inclement weather, especially in Southern New Jersey. Numerous thunderstorms developed tonight. The first around rush hour produced frequent cloud to ground lightning and very heavy rainfall. The second, late tonight prompted severe thunderstorm warnings for quarter sized hail and damaging winds in excess of 60 MPH. Numerous reports of 30 to 45 MPH wind gusts were reported between 9:00 p.m. and 11:00 p.m. It is too early to confirm wind damage reports with the thunderstorm line, but power outages have been reported in the counties in which it moved over…but some of these outages could also be related to the strong, non-thunderstorm wind gusts.

The second line prompting the warnings is ongoing due to elevated warm air advection. The warm air is aloft as the marine flow is at the surface. The marine flow just hasn’t been able to win out tonight with the stable, oceanic air that typically keeps a cap on the development of thunderstorms. A strong jet aloft and a relatively cold pool of air has been responsible for the hail and wind.
East-northeast winds will be gusty and additional showers and thunderstorms are possible through the overnight.





So far Atlantic, Burlington, and Ocean Counties have been under a severe t-storm warning.
