This morning we have an excellent example of why winter storms are so hard to come by in the northern Mid Atlantic and why all features must be in place just right. In this case, the Sub Tropical disturbance certainly delivered with an energetic and impressive storm developing off the North Carolina coast. A [...]

This morning, I discussed in great detail on what the model guidance was suggesting will occur over the next 24 hours that will keep the heavy rainfall associated with the remnants of Ida and the Sub Tropical disturbance well to the south. The idea even now in the model guidance is that the disturbance [...]

This pattern for October is about to get a lot more interesting for the Mid Atlantic over the next several weeks. However, before I dive into all the fun details I’m looking at this morning, lets deal with the here and now!
A cold front is slowly moving through eastern Pennsylvania and western New Jersey [...]

Much of the Philadelphia and New York City metropolitan areas are starting off very chilly this morning with temperatures in the mid to upper 40’s throughout the region. Temperatures will rebound into the 50’s and 60’s for afternoon highs, but even for the first day of October, the temperatures today will average well below [...]

Over the past several days, much of the New York City and Philadelphia metropolitan areas can expect dry and very comfortable weather conditions. A strong upper low anchored over New England will continue to be positioned in such a way to produce strong convergence and confluence over the northern Mid Atlantic. This in turn [...]

A cold front will continue to slowly slide off the coast this afternoon as a trough over the Great Lakes moves towards New England. The cold front will initially stall over the coastal waters this morning, however as the upper level trough lifts to the northeast, upper level winds will shift to the west [...]

There is a slight uptick in activity over the Tropical Atlantic this morning. The most obvious area of disturbed weather is over the central Tropical Atlantic where a strong disturbance is organizing. This disturbance is producing a significant amount of convection around a developing low level center of circulation. Upper level winds will continue [...]

The early fall pattern can sometimes give us a preview of some characteristics of the late fall and possibly winter pattern and if that’s the case, then the one characteristic that really stands out is amplification. Over the next several days, a strong ridge will build over the western third of the nation up [...]

The remnants of Fred continues to track to fight back, however the future of this disturbance and the one further to the east have a rather impressive road block to the west in the form of a deep trough over the western Atlantic.
Showers and thunderstorms have once again fired up on the northeastern quadrant [...]

I want to start this post by saying that what I am about to write is a theory, an unproven theory at that, which has been rattling around in my brian for the past several days.
As we all know, the Tropical Atlantic season has been less than stellar with very few tropical systems impacting [...]
