***Overnight models have shifted the snow farther south for the storm early next week***

Writer's picture: My Personal Weatherman™My Personal Weatherman™

- With the active pattern continuing, we obviously have the storm for today into tomorrow with rain for Long Island and snow well to the north as it has shifted farther north. See the latest snow map below in the 2nd image. Keep in mind that the highs for tomorrow will be highly dependent on how far northeastward the warm front makes it, so, for example, it's possible that southwestern Nassau makes it to 60 degrees with highs only in the low 40's by Montauk, so there will be a wide range of temperatures with high bust potential (notice the wide uncertainty bar for tomorrow in the last image).

- You already know about the brief shot of cold air for Friday/Saturday with windy conditions on Friday with temperatures falling.

- A couple of weak systems swing through the northeast this weekend. Can't rule out some flurries or snow showers late Saturday and then farther north in New England on Sunday from the 2nd weak system.

- There has been a substantial shift in some of the models and ensembles for the storm early next week with the secondary storm forming farther south now and moving more ENE than NE. It leads to a colder and snowier scenario for southern New England with Long Island even being in play for some wintry weather if this shift holds and trends a little farther south, so stay tuned for more updates!
