Black ice risk Monday night, cautions weather service

Another blast of Arctic air is pushing through Long Island, likely dropping temperatures below freezing for Monday night and into Tuesday morning, the National Weather Service said.

The rapidly declining temperatures, going down to the teens Monday night, could pose a risk of black ice for drivers, said David Stark, a meteorologist based in Upton with the National Weather Service. The service issued a hazardous outlook for black ice from Monday night to Tuesday morning, including the rush hour.

"Any water left standing on the road will likely become black ice," Stark said, adding that people should also watch out for black ice on walkways.

From about 6 p.m. Monday through 6 p.m. Tuesday, high pressure is expected to build eastward and into the mid-Atlantic states, creating some gusty winds, dry conditions and very cold temperatures, with highs and lows expected to be 15 to 20 degrees below normal, the service said.

The cold snap, courtesy of another Arctic cold front, is likely to last until Friday, when daytime highs in the mid 30s are expected.
