This morning I discussed my concern for convective snowfall along the New Jersey coast in the public post. I wanted to give more details on this threat this morning.
This morning I took a look at the latest sounding from OKX, which is on Long Island. Granted, the sounding is still a bit of [...]

Tropical Depression Henri continues to fall under the influence of strong southwesterly shear with the center of circulation located southwest of the strongest convection this morning. Henri will continue to weaken over the next 24 hours and likely dissipate by Friday morning.
The rest of the tropical Atlantic remains quiet. A deep trough and [...]

The Tropical Atlantic remains slightly more active compared to the previous few weeks. Tropical Storm Grace is now history as the remnants race into western Europe. However, a new tropical storm, Henri, has formed to the east of the Leeward Islands.
Tropical Storm Henri continues to get slightly better organized overnight, however it is clear [...]

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 remnants of Fred is still trying to hold on over the central Atlantic as showers and thunderstorms continue to flair up to the north of the weak low level center. There is a slight chance that this disturbance redevelops into a tropical depression once again, but the threat of this system impact any [...]

As expected, Fred continues to weaken under the influence of strong southwesterly shear. The shear is forcing much of the convection of Tropical Storm Fred to the east of the center of circulation.
Over the next 48 hours I expect Fred to continue to weaken and will no longer remain an organized tropical system by [...]

Action in the Tropical Atlantic picked up last night as Tropical Storm Fred formed off the African coast. The developmental process of Tropical Storm Fred is rather impressive as the low level circulation with Fred was well on the way of maturing while exiting the African coast. The outflow with Tropical Storm Fred is [...]

The main story in the Tropical Atlantic this morning is a very impressive tropical wave coming off the African coast. This wave is exhibiting a strong low level circulation and thus far a well developed area of convection around that center. For now, the upper level environment is favorable for development and the potential [...]

With the remnants of Erika being torn apart by southwesterly shear, the tropical Atlantic is generally quiet this morning.
One disturbance bares watching to the west of the Cape Verde Islands. This disturbance has a strong low and mid level circulation, however lacks strong convection around the center of the weak low pressure system. While [...]

The life of Erika may not last for too much longer. Erika continues to remain very disorganized this morning with a low level circulation that appears to be disintegrating. Erika still continues to produce strong convection around the poorly defined center of rotation, however strong shear from the southwest continues to keep the majority [...]
