A major winter storm is starting to develop over the Gulf Coast that will have a lasting impact on the entire northern Mid Atlantic tonight through Friday evening.
This morning, the water vapor satellite picture shows two disturbances beginning to interact over the Tennessee Valley. By this afternoon, these disturbances will form a powerful upper [...]

The latest 12Z NAM is out and boy does it deliver a heck of a snow storm!
The basic idea of the 12Z NAM is to take the 500 MB low over the Tennessee Valley and basically park that upper low over the central New Jersey coastal waters and over Long Island on Thursday [...]
10:00 PM
My thoughts this evening on the storm for Friday night through Sunday morning has not changed much. The overall development of the storm will depend on the development of the Polar Vortex and the interaction of the Arctic cold front with the Sub Tropical disturbance.
The initial set up for this storm on Friday afternoon [...]

This morning, a strong Sub Tropical disturbance is driving out of the Mississippi Valley and moving towards the Tennessee Valley.

The pressure gradient over the New York City [...]

As of last night, the majority of model guidance started to take a decided jump towards a solution where much of the East coast with the exception of northern New England will miss out on what could have been an impressive snowfall. So what are the models seeing and does the solution thus far [...]
9:26 PM
This evening, the movement of high pressure into the Atlantic highlights an environment not favorable for a significant snowfall over the northern Mid Atlantic. Temperatures, although cold, are still hovering around freezing along the coast. As the surface high pressure system slides to the east, winds will back to the south leading to a [...]
