Coastal Flood Warning Sunday Rain Sunday Night
Long Island is under a Coastal Flood Warning for Sunday’s high tides. Low pressure is off the Southeast coast and while it sits there overnight, it will start a northward move on Sunday. Moderate coastal flooding is expected at the high tides Gale warnings are in effect for the coastal waters overnight into Monday as the coastal storm goes by to the east.
Sunday morning into the afternoon. Meanwhile it is a cold night ahead with clear skies for now though some clouds will come in later tonight . Lows will be in the low to mid 30s with a gusty northerly wind that will turn more northeasterly during tonight. There are no issues on the regional or local radars nor will the be for the overnight night and into the daytime Sunday.

REGIONAL RADAR
On Sunday the strong high to the north will start to inch slowly eastward as our winds go from northeast to east northeast. Clouds will increase and thicken. Temperatures will reach into the 40s. Winds will pick up to 20 to 30 mph at times with higher gusts along coastal areas. I don’t expect any rain during the day on Long Island but it will have a raw feel to it for much of the day.
The coastal storm rides northward along 70 degrees west or just to the east of that and brings the western edge of rain to Long Island during Sunday night and continues on and off on Monday before pulling out to the east Monday evening. This rain should not amount to much. Temperatures will be in the raw 40s on Monday. Weather conditions should improve on Tuesday with clouds and some sunshine along with a gusty wind. Highs Tuesday will be just into the 40s. 
As far as the rainfall is concerned it really shouldn’t amount to much with up to a half inch on the east end and quarter of an inch or less to the west. The low is just far enough east to spare us anything major rain wise and it is possible that even these numbers are too high if the low gets kicked out a little further to the east.
