Update on the big storm with all of the maps and the Long Island forecast:
The higher resolution Euro and NAM models continue to be the most aggressive with the strength of the storm, deepening it to below 980 mb. The overnight Euro run shifted back east with the heavy snow, and it's also showing around 3 inches of rain for Long Island with wind gusts over 50 mph, especially for eastern Suffolk. The National Weather Service is forecasting gusts of 40 to 45 mph for eastern Long Island with rainfall amounts of 1.5 to 2 inches.
See all of the images below for the complete picture, and I will continue to update throughout today and tonight.
