The quick hitting arctic blast has delivered as expected and this morning was by far the coldest morning of winter in the East. Temps fell into the 20s down to the Gulf Coast.

This morning’s lows.

-27 in NW Maine.

-24 in Upstate New York, -15 Vermont.

It was a cold morning in the Mid-Atlantic.

As cold as it may be today, let’s not forget that it’s January. This looks and feels worse simply because it’s been so warm.

Looks can be deceiving…. What a beautiful afternoon in New York. However it’s arctic air that’s making for such clear skies.

Cold it may be but it remains snowless for the Big I-95 cities.

Check this out, Chesapeake ‘Bay effect’ snow brought a little white to the dunes of Cape Hatteras, NC overnight.

That band was visible on satellite. Note how clear skies were over land.

Philadelphia dipped to 12 degrees this morning. What’s very interesting is that 5 out of the last 9 winters have seen a morning colder than this morning.

Tonight will be another chilly one but not as cold as this morning as heights rise and the arctic air leaves.

As we progress through late this week, the storms pushing into the West deepen the West trough and in doing so, the eastern ridge gets pushed ENE.

That Northeast ridge eventually hooks up with the Greenland ridge as it does so, arctic air building over north-central Canada gets released south.

See today’s video for the discussion.
