Quick 4 AM update with changes for this storm and a brief look at next weekend and the LI forecast:
There have been big changes overnight with the storm for today into tomorrow with reduced snow amounts for New England. It looks like the storm will move farther east and not come close enough to the Maine coast anymore to bring the high snowfall amounts. It's rare to see such a large and rapid change in the models so close to the storm. As for Long Island, it's still just rain, but a brief period of sleet is possible later this morning and then a very slight chance again tonight of some sleet or snow mixing in, but no accumulations.
Regarding the potential storm next weekend, it looks like it may be a close call for the northeast, but the odds still favor it moving a little too far offshore, but it could skim the coast. The Euro ensembles are less bullish than the previous run in a snowstorm for Long Island, but a handful of the ensemble members are still showing snow. It should start to come into focus in the next couple of days.
