NJ Faces Storm Threat: Flash Floods Possible Monday, Severe Weather Tuesday
27 Jul
Summary
- Isolated thunderstorms may cause flash flooding early this week.
- Severe weather risk increases Tuesday with widespread showers and storms.
- Uncertainty remains regarding storm track and heaviest rainfall locations.

The upcoming week in New Jersey is forecasted to bring a return of showers, thunderstorms, and humidity, beginning Monday and extending through at least Thursday. Isolated thunderstorms on Monday afternoon could bring strong wind gusts and brief, heavy downpours, with the entire state under a marginal risk for severe weather. The potential for excessive rainfall leading to flash flooding is particularly noted for early this week.
Widespread showers and thunderstorms are anticipated throughout Tuesday, with southern New Jersey counties under a slight risk for severe thunderstorms. A stalled or slow-moving front might dump the heaviest rainfall in northern and central counties, increasing the risk of flash floods. Scattered storms are also likely on Wednesday afternoon, though the threat of severe weather and heavy rain will be lower than on Tuesday.
The risk of scattered showers and storms is expected to gradually decline on Thursday and Friday as the storm system moves eastward. However, forecasters indicate ongoing uncertainty regarding the precise track of the storm system and the areas most likely to experience the heaviest rainfall.
