Latest update on this storm and the next storm:

- Everything seems to be basically on track with this storm, although it looks like the snow will arrive a little later than expected with it possibly arriving around 8:00 tonight in western Long Island and 10:00 or even a little later out by Montauk. It still looks like a period of moderate to heavy snow with possibly some sleet mixing in along the south shore after 1 AM.

- This new HRRR run only goes out 18 hours, so I have included the future radar in super-smooth 15-minute increments from 8 PM to 3 AM. The green on the leading edge is either not expected to reach the ground or possibly be light rain.

- I have included a snapshot of the projected snowfall at 4 AM tomorrow from the HRRR model in the 2nd image.

- In the 3rd to 5th images, I have included maps from the Canadian, GFS, and ICON for Friday night for the Friday afternoon into Saturday morning storm. Let's see what the Euro and ensembles show later. The basic idea is a strong storm initially cuts west with cold high pressure to our north, and then secondary low pressure forms and passes maybe just south of Long Island. Let's see which way things shift in the next couple of days.

Are you still calling for 3-5 inches?

Replying to

Yes, but the 3 to 5 is mostly for the northern half of Nassau and northwestern and northcentral Suffolk. Generally 2 to 4 inches elsewhere, but more like 1 to 3 inches along the immediate south shore and east end. There are almost always surprises, so we will se how it plays out 😁
