Quick 4 AM update as Tuesday trends warmer, but Thursday trends snowier:
Happy Valentine's Day!
The freezing rain and snow continue to trend more to the northwest for the late Monday night into Tuesday storm, and it will also be moving through quickly, so that Long Island may see some sun Tuesday afternoon.
It's looking more likely that there will be snow with accumulations on Long Island on Thursday late morning into late afternoon before changing to rain as there will be cold high pressure to the north, so it has the look of a quick thumping of snow. Both the Euro and the NWS model blend trended snowier for Long Island and southern New England. The Euro ensemble mean is now around 4 inches for Long Island. It will turn to sleet and then rain though and last into Friday.
