- The Long Island forecast all the way to next Wednesday is below with all 3 storms likely being all or mostly all rain for us.
- The tracks for the Sunday late afternoon into Monday and Wednesday into Thursday morning northeast storms are coming into better focus with not much in the way of shifts as they both look to possibly take a very similar track along the northeast coast, which brings rain for Long Island and southern New England with snow to the northwest.
- Both the Euro and GFS are showing a smaller (narrower) snow field for the Sun/Mon storm and a more expansive (wider) snow field for the mid-week storm.
- I have included the 8-day snow maps below, which cover all 3 storm systems combined, and I will continue to update. The 6th image is the snow map for today through tomorrow.
