4:15 AM update on the snow squalls, the Long Island forecast, and the late-week storm:
- There haven't really been any changes to the northeast snow squalls, except maybe slightly weaker on the southern end, so maybe not as strong for the south shore of Long Island. The stronger band comes through Long Island from 3 PM to the west and 5 PM out east, and you will feel it as the wind will gust to 40 to 50 mph and the snow could be moderate to heavy for 10 to 15 minutes. The temperatures on Long Island will reach 40 degrees, but then sharply drop once the Arctic front comes through into the 20's by 6 PM and the teens overnight. The Wind Advisory for Long Island is from 1 PM to midnight.
- Remember, Snow Squall Warnings will likely be issued throughout the northeast today once the front gets closer to your particular location.
- Nice sunny skies for tomorrow and Monday before rain for Tuesday afternoon into early Wednesday morning.
- The late-week storm will bring significant snows to central to northern New England with snow to sleet to rain for Long Island with light accumulations before the changeover. The timing is generally Thursday evening into Friday afternoon.
