...MONDAY JUNE 14 2021 8:14 AM EDT...
Frontal low pressure system offshore of North Carolina quickly develops well-organized thunderstorms overnight...formation of a tropical depression or storm is likely over the next few hours today! This system will be steered quickly northeast by the upper trough and developing surface frontal low currently moving into eastern Canada...in alignment with the upper SW flow ahead of the upper trough which thus could reduce the shear over this system...and in fact the divergence on the east side of the upper trough may instead aid this system’s thunderstorms and tropical development. Tropical development after 24 hours will be precluded by arrival to cooler waters and absorption into the much larger surface frontal low. This system will bring choppy seas to marine interests offshore of the northeast US and Atlantic Canada...with brief episodes of coastal sea swells and rip currents along the US Mid-Atlantic and New England as well as the Nova Scotia and Newfoundland coasts of Atlantic Canada should this system quickly intensify into a tropical storm.
For the potential Gulf of Mexico tropical development this week...see full post #19 on the home page of this site.
