Winter isn't coming — it's here. Or at least the weather is.

While the fall months have been unseasonably warm, those pleasant temperatures are about to take an extreme dip towards the end of the week.

According to Accuweather, as the cold front moves in on late Tuesday, the moist air coming in from the Atlantic Ocean may cause some wintery precipitation all along the Northeast. At the moment, it’s too early to tell whether the storms will create flurries or heavier snowfall.

Winter storm watches are likely to be issued as early as Wednesday morning along the I-95 corridor, stretching between most of the larger cities on the eastern seaboard, mainly between Portland, Maine and Washington, D.C.

“A storm that tracks close to the coast and gains only a moderate amount of strength would be successful at bringing a stripe of accumulating snow from New York City to Boston,” said AccuWeather Chief Meteorologist Elliot Abrams, “and perhaps as far to the southwest at Philadelphia and Washington, D.C.”

There may be a brief break from the cold closer to the end of this week, with highs in the 50s, but by next week, highs of the 20s and 30s are in the forecast for most of the Northeast.

And that isn't the only region of the U.S. that will be shivering by this weekend: According to Accuweather, some cities in the Southeast and the lower Mississippi Valley will experience temperatures that are 20- to 30-degrees cooler this week than the previous week. Even some very southern areas may experience a freeze.

Looks like everyone on the East coast should grab their warm jackets.
