LATE-WEEK NOR'EASTER?

It may only be Monday, but there is reason to highlight the chance for a coastal storm Thursday into at least part of Friday that could end up being classified as a nor'easter with persistent northeast wind. While there is still a wide range of potential impacts on the table several days away - from periods of rain showers and breezy conditions to heavier rain and more intense wind gusts around 40 mph - plan to need the rain gear, starting Thursday afternoon.
There will be a couple of areas of low pressure around, but the exact location and strength of those systems will determine the local impacts - amount of rain, wind and any minor coastal flooding - here on Long Island. That will become clearer tomorrow and Wednesday.
The News 12 Storm Watch Team will continue to provide updates for you on what's expected for the end of the week several times per day, so keep checking back for updates.
You may also be hearing about first snow of the season chances for the northeast during the end of this week. While that is true, that is not the case for Long Island. Those snow chances will remain far away to the north and west - toward the Poconos, Catskills and higher elevations.
