New Jersey Weather: Warm Halloween Forecast for Trick-or-Treaters. Some rain is possible this week.

There will be two opportunities for long-overdue and much-needed rain in parts of New Jersey this week, although mild and dry conditions are expected for Halloween trick-or-treaters.

Forecasters say Thursday could see record temperatures due to Halloween celebrations.

October looks almost certain to be the state's driest month on record.

There is a 15% to 25% chance of light rain in northwestern parts of the state on Tuesday, while the rest of the state is expected to remain dry.

There is another chance Thursday night into Friday, although “the latest forecasts appear somewhat less enthusiastic about the likelihood of measurable rain,” the National Weather Service said in its Tuesday morning forecast discussion. “Nevertheless, it should be fairly short with drier air returning during the afternoon.”

The weather service's New York office, which covers New Jersey's five northeastern counties (Bergen, Essex, Hudson, Passaic and Union), says there is a 25% to 40% chance of rain during the same period, but found that Precipitation is more likely east of the Hudson River.

According to the U.S. Drought Monitor, all of New Jersey is either unusually dry or experiencing moderate or severe drought.

Tuesday will be mostly sunny, with highs in the 60s, falling into the upper 40s and lower 50s at night.

Wednesday and Thursday will be even warmer – in the mid-70s, before much of New Jersey flirts with 80 degrees on Halloween.

Overnight lows will be mild in the 50s both nights Wednesday through Thursday and then in the 60s as November rolls into Friday.

Forecasters are predicting a high of about 80 for Newark and Trenton, which would be below the Oct. 31 records of 82 and 81 set in 1946.

According to the weather service, the high at Atlantic City International Airport on Thursday is expected to be 75, well below the 83 the airport reached in 1946.

Normal highs in late October range from the lower 40s to the upper 50s and lower 60s in New Jersey.

As of Tuesday morning, there had been no rain in Trenton for 30 days and in Atlantic City for 26 consecutive days, the weather service said.

The record for the longest stretch without measurable precipitation in the two cities is 38 days (ending May 23, 1903) and 34 days (ending September 15, 1995), according to the weather service.

Philadelphia set a record of 30 consecutive days without precipitation when Monday ended without a drop of rain.

Despite the ongoing dry conditions, there is no increased risk of wildfire spread in New Jersey on Tuesday. As of Monday, 242 fires remained active in the state and had not been declared extinguished, state officials said.
