Update on the complex systems ahead and the Long Island forecast:
Not much has changed since my previous posts, and I have the updated Long Island forecast below. It's obviously quite complicated, but that's what it looks like as of now. The 1st and 2nd images are from the NWS NY for Long Island and the Tri-State area for the weekend and the storm early next week. While there may be a coating to a half-inch of snow tomorrow afternoon into evening, there may be not be any snow at all on Tuesday as it may be freezing rain and then rain. The best chance for 2 or 3 inches of snow before changing to ice and then rain is Thursday morning. The 3rd image shows the model blend snowfall for the next 7 days, so you can see there will be a lot of snow for areas that are on the colder side of the storm. The 4th image is for Long Island and shows the gradual warming trend over the next 3 weeks.
