Polar Air Madness Returns As East Coast Winter Threat Rises

Average temperatures across the Mid-Atlantic, including Washington, DC, have trended above the 30-year normal in recent weeks (pressuring NatGas futures) following an Arctic plunge in early December, but a second cold blast of the season is expected to arrive by the end of the week, bringing the risk of winter precipitation by late weekend that could extend into early next week.

“Not one, not two, not three, but four or five plunges of polar air will probably hit the United States through the end of the month. The third, fourth, and fifth episodes currently look to bring the most severe cold,” meteorologist Ben Noll wrote on X.

Warm grounds and marginally cold air temperatures will work against a big event.

Still in the game. There will be two chances for snow around Baltimore this weekend. Snow showers on Saturday could produce a coating of snow in some areas. Then there’s the coastal storm on Sunday. The trend on that storm is NW. Models are split on getting the snow into… pic.twitter.com/r3keHoClMb
