Maps for the first storm, but the main focus on the Long Island snowstorm on Thursday:

Details for Long Island for today and tomorrow are in the forecast below as a Winter Weather Advisory is in effect, and all of the maps for the northeast are shown below.


Thursday continues to look like a snowstorm for Long Island with snow developing probably between 6 AM and 10 AM, and it will be a dry snow to start with temps in the mid to upper 20's. Accumulations of 4 to 6 inches are possible before changing to sleet/freezing rain and then rain in the evening. The rain will then continue into Friday morning.
