Aug 3: Thunderstorms Possible for NNJ Later

Today should be mostly sunny in New Jersey however some funky energy should move through to our NW later this evening and overnight. The main player is a low pressure disturbance in SE Canada which will drag a series of frontal activity through the Ohio Valley/PA region between this afternoon and tomorrow morning. The lower 2/3 of New Jersey should generally miss out on this but NWNJ could see showers and thunderstorms. The National Weather Service Storm Prediction Center (NWS SPC) has issued the following convective outlook which illustrates the threat being mostly to our NW (SLGT area is better chance of storms):

Expected timing is extremely hard to pin-point given the dynamics and axis (W/NW-E/NE) of the energy. The best I can do is between a general period between 8PM and 3AM for the more organized storms to roll through NWNJ. Isolated showers and thunderstorms are possible earlier in the afternoon but that’s a lesser chance. This is the high-res NAM showing estimated precipitation between 1AM and 2AM. Again, I believe this can happen anytime between the general period I stated. Also please note that the rest of New Jersey is dry:

In English: Most of New Jersey can expect a mostly sunny, warm and humid day today. NWNJ has a chance for isolated showers and thunderstorms later in the afternoon and then a more concentrated area of showers and thunderstorms overnight. The NWS will issue Severe Thunderstorm Warnings should wind gusts exceed 58mph and/or hail reaches a diameter of 1 inch or greater. I would expect most storms to stay just under severe criteria with only isolated and localized instances of severe. I’ll be watching. Be safe! JC
