Warm today with 75 degrees in NYC, but some snow can't be ruled out on Tuesday, even on Long Island:
You can see the projected highs for today from the HRRR model in the 1st image. The details for Long Island are in the forecast below, but a cold front will come through early tomorrow morning with a chance of some showers, although it will still be mild. Cooler for the weekend and then cold on Monday into Tuesday morning. The Euro then shows snow changing to rain Tuesday afternoon for Long Island and southern New England. Some of the other models keep the system weaker and farther south. Several of the Euro ensemble members do show some snow, so it's possible, but the chances of accumulating snow would have to be considered very low, as of now.
The projected snowfall in Boulder, Colorado this weekend is literally off the charts (2nd image) with the GFS ensembles showing around 50 to 70 inches, although 30 to 40 inches might be more realistic.
