Radar and snow maps for the snow tomorrow:
Here's the simulated future radar for tomorrow from 4 AM to 8 PM from the NAM model. There could be some wet snow showers on Long Island between late morning and mid-afternoon. The earlier they arrive, the better chance of snow showers, as opposed to rain showers.
The 2nd to 4th images are the snow maps through 1 AM Thursday from the HRRR, NAM, and National Weather Service, respectively.
