With heat advisories in place across much of the state as another hot and humid day grips New Jersey, forecasters say possible heavy downpours could lead to flooding Friday afternoon and evening.
There’s also a shot of rain on Saturday and Sunday, in what will be another very warm weekend.
The precipitation on Friday won’t last for hours, though “when it is raining it could be quite heavy,” the National Weather Service said Friday morning. The best estimate for storms arriving is around sunset — approximately 8:10 p.m.
Rain is likely to overspread most of the state at some point. In addition, there is an elevated risk for lightning accompanying Friday’s storms.
AccuWeather.com says “drenching downpours” might lead to flooding in urban areas and the flooding of small streams, with the main window for rain from 5 p.m. to 9 p.m.
Otherwise, the pattern of hot, humid weather will continue Friday. Conditions won’t be nearly as stifling as on Thursday, but temperatures will still top out in the low 90s across much of the state. The heat index, which indicates how hot in will feel once the humidity is factored in, will be mainly in the mid to upper 90s.
A heat advisory remains in effect until 8 p.m. Friday for Bergen, Burlington, Camden, Essex, Gloucester, Hudson, Mercer, Middlesex, western Monmouth, Ocean, Passaic, Somerset and Union counties.
Saturday will still be plenty warm with highs of around 90 and heat indices in the mid to upper 90s under partly sunny skies. Afternoon showers and thunderstorms are again possible — the weather service says there’s a 20% to 50% chance of rain.
Sunday is expected to be the hotter of the two weekend days as temps settle in the low 90s with plenty of humidity. Once again, afternoon storms can’t be ruled out. The heat index will climb to 100 over a large portion of the state, the weather service said Friday.
