Update on the multiple systems that may bring snow and the Long Island forecast:
- First, here is the link to the final snowfall totals for the Tri-State region from the snowstorm yesterday. Mostly 4 to 8 inches on Long Island with a few spots that received amounts above or below that range. https://mesonet.agron.iastate.edu/wx/afos/p.php?pil=PNSOKX&e=202102080247
- Overall, the forecast is starting to come into focus. There will be a weak system tomorrow that may bring 1 to 2 inches of snow on Long Island (see below for the forecast details for Long Island) with a little more north and northwest of Long Island (see 1st to 5th images for snow maps).
- It then looks like the Thursday morning system won't be a big storm and Long Island may be on the northern fringe, but we may get another 1 to 2 inches of snow then.
- Then there will be another weak system for Friday for the northeast, which may bring another inch of snow to Long Island.
- The real storm to watch for Long Island and eastern New England is a potential coastal storm from Saturday evening into Sunday morning. As of now, the best chance for accumulations are Suffolk and eastern MA. I will definitely be watching this potential storm.
- Then the next storm for the middle of next week may cut to our west, so we may get rain.
- Overall, below average temperatures this week into this weekend, and then around average temperatures next week.
