Isolated Thunderstorms Later Today



A warm front is currently lifting through North-Central New Jersey, with plenty of sunshine to the south of the boundary.

Despite increasing instability with daytime heating---I don't see too many things out there to trigger thunderstorms here in New Jersey. I think the primary threat for thunderstorms will be in Pennsylvania today. However, a sea breeze front or bay breeze front could initiate an isolated t-storm. With the warm front lifting northward, a hidden boundary riding along it may also pose a risk for an isolated shower or thunderstorm.

The 06z GFS was a bit more robust with the thunderstorm chances for today, compared to the 12z NAM. Any thunderstorm that does form, could potentially produce strong gusty winds, hail, and dangerous lightning. Otherwise it will be a sunny day with warm and humid conditions. Some southern sections may inch towards the 90 degree mark.
