It may be time to say goodbye to warmer weather. The National Weather Service issued its first forecast for snow this season for parts of New Jersey and Pennsylvania.

Forecasters say light snow is possible Thursday night into Friday morning for northwest New Jersey and Pennsylvania's southern Poconos and Lehigh Valley.

The National Weather Service is emphasizing only light snow accumulations are possible.

The potential for the snow comes less than a week after a tornado touched down in Morris County. New Jersey has seen an active tornado season this year, and there seems to be some correlation between a busy tornado season and early snow.

State climatologist Dr. David Robinson says that in 1989 New Jersey saw seven tornadoes in one November day, quickly followed by an early snowfall.

“What followed the event on Nov. 16, 1989 – we had 6 inches of snow in central New Jersey on Thanksgiving morning,” he says. “The pattern stuck after that squall line with tornadoes, and December was the coldest on record in New Jersey.”

Parts of New Jersey that see accumulating snow may also have to deal with storm damage since many trees in the state still have leaves left on them. But forecasters are predicting less than an inch of snow this week.

Many New Jersey residents may wonder if the state will see an active winter this year.

“It is extremely difficult to make long-range weather predictions for the winter, or any other season for that matter, here in the Middle Atlantic States,” says Robinson.

Weather experts are calling for New Jersey to see above-average temperatures for the winter.
