New Jersey's stretch of warm, dry weather is set to end Thursday, the 5th, as a cold front approaches, with rain intensifying from Thursday night through Friday, the 6th. After a long dry spell, roads may be slick and flash flooding is possible, Patch reported. Starting Saturday, the 7th, skies will be mostly clear and temperatures will fall.
According to Patch, New Jersey's warm, dry weather ends Thursday, the 5th. As a cold front approaches, rain will intensify from Thursday night through Friday, the 6th, with the potential for flash floods and thunderstorms. The National Weather Service expects the front to move out and conditions to turn mostly dry starting Saturday, the 7th.
The National Weather Service said that because the front approaches from the west, the chance of rain will rise Thursday during the day in the western part of the forecast area. The metro area and points east are expected to stay mostly dry, with a precipitation chance of 30% or less. The chance of rain increases from Thursday night into Friday.
Expected rainfall varies widely by region. The Jersey Shore could receive 1–2 inches (about 25–51 millimeters), and locally 2–3 inches (about 51–76 millimeters). Most of the rest of the state is expected to see anywhere from a trace to 1 inch (about 25 millimeters). The National Weather Service said it is still uncertain where the heaviest rain will fall, which depends on where the front stalls.
Because it has not rained for some time, roads may become slick and flash flooding could occur. Brett Anderson, a senior meteorologist at AccuWeather, said strong rain clouds could repeatedly pass over the same areas, creating conditions that can quickly lead to flash flooding.
After the front passes, temperatures will drop noticeably. The National Weather Service forecast Saturday, the 7th, highs in the upper 50s to mid-60s Fahrenheit (about 14–18 degrees Celsius) and overnight lows mostly in the 40s (about 4–9 degrees Celsius). From Sunday, the 8th, through early next week, it will turn cooler, with highs in the upper 50s to low 60s Fahrenheit (about 14–16 degrees Celsius) and lows mostly in the 30s (about 0–4 degrees Celsius, in the 40s in the metro area). The possibility of scattered showers over the weekend has not been ruled out.
