Active pattern continues with snow and ice mostly north of Long Island and a brief shot of cold:
- The little system moving through this morning is bringing rain to Long Island with some snow for southern New England.
- Another quick shot of rain to the south and snow to the north for later this afternoon into early evening.
- Then the main system for tomorrow afternoon into Thursday with rain on Long Island (possibly briefly mixing with sleet near the beginning away from the south shore) and ice and snow to the north (see snow and ice maps below, which only go through 7 PM Thursday).
- A brief shot of Arctic air with temperatures dropping on Friday with gusty winds with lows in the upper teens on Long Island by early Saturday morning and only getting into the low 30's for highs on Saturday.
- The weak system moving through Saturday night could produce some flurries, but it will really strengthen offshore and become a monster ocean storm, and there is a chance of some enhancement to the precipitation shield over the northeast on Sunday with some snow showers.
- A very strong storm for Monday into Tuesday will then cut west with a secondary strong storm forming near Long Island or southeastern New England on Tuesday. So, while there is still uncertainty, it could begin briefly as snow on Long Island, but as of now, it looks like a mainly rain event for Long Island with the potential for a snowstorm in interior central to northern New England.
