Light snow back in play now for L.I. late tonight and update on the snow for the weekend and Tues:

- There is a Special Weather Statement for Long Island this morning until 8 AM for black ice, so please be careful this morning.

- While it won't be a big event, light snow is now likely for Long Island for late tonight into very early tomorrow morning (around midnight to 7 AM) with up to an inch possible.

- The system for Saturday night into Sunday morning won't be a major storm, but it will bring some accumulations to the northeast with some mixed precipitation likely along the coast. The details for Long Island are in the forecast below, but 1 to 3 inches of snow is possible along with some sleet, freezing rain, and rain before ending by late morning on Sunday.

- Tuesday will be a bigger storm that will bring widespread snow to the northeast. The GFS, Canadian, and ICON show mostly snow with some sleet for Long Island, but the Euro has a warmer solution, which seems unlikely at the moment, so I am discounting it unless it shows it again this afternoon. The NWS model blend shifted the rain/snow line southeast, which seems more likely.

- I will continue to update on all of these systems.


Today: Mostly sunny in the morning and then increasing clouds in the afternoon with highs in the low 30's. Light winds out of the NW at 5 to 10 mph.

Tonight: Light snow developing around or just after midnight with lows in the mid 20's. Total snowfall by 8 AM of around 1 inch.

Thursday: Light snow ending by around 8 AM and then mostly cloudy. Highs in the low 30's. Wind out of the north at less than 10 mph.

Friday: Mostly cloudy in the morning and becoming partly cloudy in the afternoon. Cold with highs in the upper 20's.

Saturday: Increasing clouds and cold with highs in the upper 20's to around 30 degrees.

Saturday night: Cloudy with a 60% chance of snow developing between 7 PM and 10 PM. Accumulations of 2 or 3 inches are possible, but it also may mix with or change to sleet. Some freezing rain and rain are also possible by Sunday morning. Lows in the upper 20's.

Sunday: Rain, sleet, or snow ending around late morning. Highs in the low 30's.

Monday: Mostly sunny and cold with highs in the upper 20's.

Tuesday: Cloudy with a 50% chance of snow developing in the morning. Moderate accumulations are possible, but there is uncertainty in where the rain/snow line will set-up. I will continue to update the forecast. Highs in the low 30's.
