Best time for this to happen, if it does, is 3 pm onward today. This may not be widespread.
Radar is not showing too much now…
Keep an eye to the sky on Tuesday. Any thunderstorms that do form in western New Jersey have the potential to be slightly more severe than normal
Unless you were out of town last night, you couldn’t but help notice the thunderstorms that passed into western New Jersey last evening. I was able to get a few descent photos of the lightning since the storms were not directly overhead where I was. All photos © 2016 Dave Dabour, Dabour Photography
...Excessive heat warning remains in effect from noon Saturday to 9 PM EDT Sunday... ...Heat advisory will expire at 8 PM EDT this evening... * maximum heat index values...105 to 110 on Saturday afternoon and 102 to 107 on Sunday afternoon. * Temperatures...highs are forecast to be in the middle 90s on Saturday and in the lower to middle 90s on Sunday. Overnight lows are expected to favor the middle and upper 70s. * Timing...heat index values will reach excessive levels during the afternoon and early evening hours each day. Scattered showers and thunderstorms may bring brief periods of relief from the heat. * Impacts...the multiple day excessive heat will increase the risk for heat-related health issues...especially for the elderly and for those with chronic health problems such as lung and heart disease. * Outlook...a frontal boundary approaching from the northwest should arrive early in the new week bringing some relief from the oppressive heat and humidity. Precautionary/preparedness actions... This excessive heat warning means that a prolonged period of dangerously hot temperatures and high humidity levels will occur. The conditions will enhance the potential for the development of heat-related health issues among susceptible individuals. Be sure to drink plenty of fluids...stay in an air- conditioned environment if possible...stay out of the sun and check on elderly relatives and neighbors. Children and pets should never be left unattended in a vehicle under any circumstance. During hot weather a car interior can reach lethal temperatures in a matter of minutes. Take extra precautions if you work or spend time outside. When possible...reschedule strenuous activities to the early morning or late evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing and drink plenty of water. To reduce risk during outdoor work...the occupational safety and health administration recommends scheduling frequent rest breaks in a shaded or air conditioned environment. Anyone overcome by heat should be moved to a cool shaded location. Heat stroke is an emergency...call 9 1 1.
...A line of strong thunderstorms will affect Warren...northern Hunterdon...Sussex...northwestern Somerset...Morris... Northampton... southeastern Monroe and southeastern Carbon counties...

So as usual, we go from hardly any rain at all to a whole bunch. The next system looks to deposit 1-1.5″ of rain to western New Jersey later Thursday into Friday.
I’ll post updates tomorrow.

Some of the thunderstorms may contain torrential rainfall and result in a localized flash flood threat. * The axis of heaviest rain remains uncertain at this time. However, the potential for localized rainfall amounts of 2 or more inches in one hour will bring the risk for flash flooding particularly in urban areas. Precautionary/preparedness actions... A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
