Update on the snow for tomorrow on LI and the Euro also shows the snowstorm next week:

  • Snow showers or a period of light to occasionally moderate snow is looking a little more likely on Long Island tomorrow morning, as both the HRRR and RGEM models show it. The NAM isn't as bullish though. A coating to an inch can't be ruled out at this time, but let's see what the models show today.

  • It's going to be a very cold weekend in the northeast. Highs on Long Island will only be in the low to mid 30's with breezy conditions, and lows by early Sunday morning and early Monday morning with been in the upper teens to low 20's.

  • Regarding the potential snowstorm for early next week, the Euro kind of stands alone in showing it on Long Island and southern New England, although the GFS-parallel also shows some snow (edit at 5:20 AM: Now the new 06Z GFS run also has snow for Long Island). While the Euro is showing 8 to 12 inches, it doesn't really have a lot of support from its own ensembles, although there are a bunch of them showing accumulations of 2 inches or more.

  • The storm tracks for next week with the 2nd storm as well for next Friday, generally will be from west to east, so it doesn't look like the classic storms coming up the coast and heading NNE. This means the chances of a snowstorm for northern New England are much lower. Parts of the Mid-Atlantic states have the best chance.
