THIS EVENING
Have a coat with you! It is still mostly clear to partly cloudy, with temperatures gradually falling through the 50s this evening. It is breezy, too, and that will add to a developing chill outside through the night.
OVERNIGHT
It will be a good idea to have a heavier winter coat overnight. It will be a dry night, but breezy and quite chilly. The sky will continue to be mostly clear to partly cloudy. Overnight low temperatures will fall into the mid-to-upper 40s. A persistent northeast wind with gusts between around 20 to 30 mph will make it feel like the upper 30s to lower 40s into early Wednesday morning.
OFFSHORE NOR'EASTER
Other than a slight chance for a passing shower over eastern Suffolk County Wednesday evening, it will continue to stay dry this week, but an offshore Nor'easter (coastal storm) is bringing some windier weather and rough surf to Long Island still from now into the start of Thursday.
Even though the center of the storm is staying well offshore, its wind field is still bringing northeast gusts of around 20 to 40 mph to Long Island through Wednesday. The highest gusts in the 30 to 40-mph range will mostly be along the shoreline and East End of Long Island. That's not necessarily damaging wind, but it will be annoying at times. Just expect decent, but windy and cool weather midweek with some more clouds around on Wednesday, too.
Here is a look at the projected hour-by-hour weather for Long Island:
This offshore storm is also bringing rough surf along the South Shore. Waves will build to around 6 to 10 feet, creating high surf and the potential for some minor beach erosion. Coastal communities, especially along the South Shore and East End, should keep an eye on conditions as we head through the middle of the week.
Beach erosion and minor coastal flooding are possible Wednesday into Thursday. Right now, the tide that would be impacted with the best chance for some minor coastal flooding would be Wednesday evening, but we are not expecting much impact at this time.
