Update on the late-week storm, tropics, and Long Island forecast:
The models continue to show the storm for Friday into Saturday with heavy mountain snow for northern New England and northeastern NY state with heavy rain and gusty winds from Long Island into New England. For Long Island, the heaviest rain would be Friday night into Saturday morning.
Invest 93L still has a 30% chance of tropical development, but if it doesn't develop today, upper-level winds will become unfavorable for development tonight and beyond.
The models, especially the GFS, continue to signal the potential for a hurricane in the western Caribbean later this month, but it's too soon for specifics.
