We’re starting our morning with a bit of an October chill across Long Island, with temperatures in the 30s and 40s. You’ll want a jacket or sweatshirt as you head out the door, but we have a nice fall day ahead. Mostly sunny skies will help temperatures climb into the upper 50s and lower 60s this afternoon. Overall, it’s shaping up to be a pleasant start to the workweek. For tonight, skies will become partly cloudy, with temperatures dropping back into the 40s, bringing another chilly start to your Tuesday morning.
Tuesday will feature a mixture of sunshine and clouds, with afternoon temperatures reaching the lower 60s for most of Long Island. Communities across the East End will stay a little cooler, with highs generally in the 50s. It will also become breezy during the afternoon, with winds gusting around 20 to 30 mph. Those winds will increase Tuesday night as a coastal storm strengthens offshore. Under partly cloudy skies, temperatures will fall into the 40s, with wind gusts reaching 30 to 35 mph, especially across eastern Suffolk County and the East End.
We’re keeping a close eye on that Nor'easter (coastal storm), which will bring gusty winds and rough surf to Long Island from Tuesday night through Wednesday and into early Thursday. Even though the center of the storm is expected to remain offshore, its wind field could still produce some impacts along our coastline. Wednesday will feature a mixture of sunshine and clouds, with more sunshine expected across Nassau County and western Suffolk, while clouds may linger longer across the East End. Afternoon temperatures will reach the upper 50s and lower 60s, but winds gusting to 30 to 35 mph will make it feel cooler, especially near the coast.
One of our biggest concerns with this coastal storm will be the rough surf along Long Island’s Atlantic-facing South Shore. Waves could build to around 5 to 10 feet, creating pounding surf and the potential for some beach erosion. The greatest coastal impacts will depend on the storm’s exact track, strength and how long the strong onshore winds persist. At this point, the bigger concern is the wind and rough surf rather than rainfall. 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. We’ll continue tracking the storm closely for any changes in its strength or impacts. Beach erosion and minor coastal flooding is possible Wednesday into Thursday.
The good news is that quieter weather returns as we head toward the end of the workweek. Winds should gradually ease Thursday as the coastal storm moves farther offshore, with plenty of sunshine returning across Long Island. Friday is looking nice as well, with mostly sunny skies and afternoon temperatures in the upper 50s and lower 60s. Overnight lows will remain in the 40s, keeping that typical October chill around during the mornings and evenings. Overall, Thursday and Friday are shaping up to be a couple of nice fall days to finish the workweek.
