You can see the projected storm locations and strengths at 7 PM next Friday in the 1st image, so there is a lot of uncertainty still in where the rain/snow line sets up, so watch for changes in the next several days.
The 2nd image shows the snow map from the NWS for the 1st system, which is Sunday into very early Monday.
The 3rd image is the NWS Model Blend snow map for both storms combined.
The 4th image shows the projected temperatures for Long Island for the next 15 days.
I may very briefly post the latest snow maps around 3 AM tomorrow (late tonight), and then I will have more updates tomorrow afternoon and evening.
