Snow maps as a Winter Storm Watch is issued for Long Island and confidence increases!

- There is better general agreement among most of the models (GFS is an outlier). The highest amounts on Long Island are still expected in eastern Suffolk, and the Winter Storm Watch is in effect from 7 PM tomorrow to 7 PM Saturday. There will still be adjustments in the snowfall amounts and the National Weather Service is still giving a 10% chance of 21 inches in Nassau and a 10% chance of less than an inch, which is remarkable. With temperatures mostly in the mid 20's while it's snowing on Long Island, this will be a dry powdery snow.

- I will continue to post the latest info throughout the day.
