Friday Overview: Heat, humidity, more thunderstorms expected

/by

The heat and humidity is back this morning, and it’s expected to stick around through the day. Temperatures will rise from the 70’s this morning into the 90’s once again early this afternoon. The combination of the heat and humidity will push heat index values into the middle 90’s once again throughout the area, despite temperatures remaining a bit cooler (as usual) near the shore.

The main story today will be the development of a seabreeze front, which is part of a larger “backdoor” cold front pushing toward our area from the Northeast. This boundary will serve as a convergence point for moisture, heat, and humidity — as well as atmospheric instability and lift for thunderstorms. An approaching disturbance in the atmosphere is likely to aid in storm development this afternoon and evening, some of which could be strong — especially over New Jersey. Some other highlights through the weekend:

  • Showers and thunderstorms this afternoon could be strong, especially over New Jersey. Localized flooding is also possible with extreme atmospheric moisture content.
  • Saturday is likely to be a much cooler day in NYC and Long Island, thanks to a northeasterly wind component.
  • Temperatures will remain hot and humid over Southern and Central NJ, where additional strong and severe thunderstorms are possible Saturday afternoon and evening.
  • Warm, but drier weather is anticipated on Sunday with northwest winds and plenty of sun.
