Quick 4 AM update as the cooler and rainy week begins, and a possible late-week storm?

- More details are in the Long Island forecast below, but the rain should arrive around mid to late morning from west to east on Long Island, and there will be more rain tonight and tomorrow. While there still can be a passing shower on Tuesday and Wednesday, it will generally be fairly cool and mostly cloudy.

- The models are now showing a potential coastal storm for Thursday night into Friday, and I have included the maps below.
