Welcome to April! Brief 3:30 AM update with the big thunderstorm threat this evening!
It still looks like a break in the action from around 3 PM to 7 PM, and then an impressive line of strong to potentially severe thunderstorms for this evening, reaching NYC around 6 to 7:30 PM and Long Island from west to east from around 7 PM to 10 PM. The best chance for severe thunderstorms is western Long Island and points west, but there can still be a strong to severe thunderstorm in Suffolk as well. The tornado threat is shown in the 2nd image. Any of these storms can contain heavy downpours, frequent lightning, and hail.
The future radar below goes from 7 AM to 11 PM.
