The National Weather Service Mount Holly Forecast Center has issued a hazardous weather outlook for Friday as a result.

“A fast moving cold front will track through the region Friday afternoon and bring a period of moderate rain, said Ray Kruzdlo, of the National Weather Service. “Thunderstorms, which could bring isolated areas of heavy rain and strong gusty winds, are also in the forecast, but mainly for southern New Jersey and the Delmarva.”

Generally speaking, only a quarter-inch to a half-inch of rain is expected across the South Jersey area, Kruzdlo said. However, rainfall totals will be high in areas where thunderstorms occur.

While the bulk of the higher rain totals will fall over western New York and western Pennsylvania, South Jersey could receive up to a half-inch of rain./NOAA While the bulk of the higher rain totals will fall over western New York and western Pennsylvania, South Jersey could receive up to a half-inch of rain./NOAA “The expected rainfall combined with snowmelt will likely cause poor drainage, nuisance flooding,” he said.

Some river models indicate some of the larger streams and rivers across the region could have significant rises, Kruzdlo said.

As a result, a flood watch has been issued for western New Jersey and eastern Pennsylvania by the National Weather Service.

Meteorologists are watching rainfall totals and temperature levels because of their combined effects on any potential flooding, he said.

Flooding is more of a risk in the Poconos and in northern New Jersey where up to 4 inches of water equivalent is now stored in the remaining snow cover, he said.

“Just a slight uptick in rainfall amounts or expected high temperatures could easily generate a more widespread flooding event,” he said. “The threat of flooding will significantly increase if rainfall amounts approach 1 inch.”

A light increase in temperatures or in rainfall totals could increase South Jersey's flood potential, according to the National Weather Service. A light increase in temperatures or in rainfall totals could increase South Jersey's flood potential, according to the National Weather Service.
