Simulated Radar and Comments from National Weather Service
- This video shows the simulated radar for today from 10 AM to 10 PM.
- The following are comments from the National Weather Service covering Long Island and the tri-state area:
- Expect scattered to numerous showers/thunderstorms to redevelop this afternoon along the slow moving frontal boundary.
- Wind fields aloft are weak, so any storms will be
slow movers capable of producing torrential rainfall. HREF PMM depicts greatest heavy rain potential just north/west of NYC this afternoon, so have issued a flash flood watch from 2-8 PM.
- Convection should quickly weaken this evening, with only a few leftover showers/thunderstorms for at least the first half of the night. An approaching shortwave trough should trigger additional convection toward daybreak.
- Tomorrow: Another round of showers/thunderstorms possible, through there is some uncertainty where this will set up, with higher-res CAM's targeting southern CT and areas just NW of NYC, while the 12-km NAM and global models are siding more with NYC metro and Long Island. HREF guidance suggesting coverage and intensity of convection tomorrow will both be less than that expected for today, so any flood threat would more likely be isolated/minor.
