First Alert Forecast: Skies clear overnight, sunshine returns Monday

A third round of thunderstorms swept through the region Sunday, but thankfully did not bring widespread damage as they did on Friday and Saturday. They did deliver heavy rainfall though, with many locations in New Jersey catching a good soaking.

Sunday night forecast

For tonight, a few residual showers are possible early, otherwise skies will be clearing, with some fog development possible. Lows will range from the mid 60s to lower 70s.

Monday forecast

Highs in the 90s return on Monday, with lots of sunshine and a slight decrease in humidity levels. A stray storm is possible late.

Unsettled week ahead

After Monday, most of the upcoming week looks quite unsettled with multiple rounds of rain combined with thunderstorms, and some of it could be heavy. The first round is likely to arrive on Tuesday, bringing slow moving showers and storms that can lead to flash flooding. As we progress later into the week, moisture from what is now Hurricane Debby will start to move northward, thus enhancing rainfall rates and totals for our region. All that tropical moisture would be capable of producing several inches of rain by week's end. Due to all the clouds and rain, high temperatures are expected to run below average, mainly in the low 80s.

Hurricane Debby update

Hurricane Debby is currently churning off the northwest coast of Florida. Debby strengthened into a Category 1 hurricane late Sunday night and is expected to eventually make landfall around Florida's Big Bend region on Monday afternoon. After landfall, Debby will slowly meander across the southeastern United States throughout the week. While it will be weaker, the slow-moving nature of the storm will allow it to dump copious amounts of rain in several states. Portions of the Carolinas and Georgia may see localized rainfall totals ranging between 20-30 inches. Catastrophic flooding would be imminent if those rainfall totals verify.
