We’re starting off Friday looking pretty good across Long Island. There may be some patchy fog early, followed by a mixture of sunshine and clouds. It’s going to be a warm day for early October, with highs in the 70s across much of Suffolk County and lower 80s across parts of Nassau County. A few spots over western Long Island could even approach the mid-80s.

Enjoy the dry weather while it lasts because changes arrive late this afternoon. Clouds will increase, with showers developing from west to east after about 5 p.m. A thunderstorm is also possible early this evening. If you have Friday night plans, keep the umbrella nearby. Showers will move through during the evening before gradually tapering off overnight. Lows will fall into the upper 50s and lower 60s.

Saturday brings a noticeable change behind the front. We’ll have a mixture of sun and clouds, but it will be cooler and a little breezy. Overall, it looks like a pretty nice fall day, with afternoon temperatures around 65 to 70 degrees.

Saturday night remains quiet and dry with mostly clear to partly cloudy skies. Temperatures will fall into the 50s, so you may want the light jacket if you’re heading out Saturday evening.

We’ll start Sunday with some sunshine, but clouds will increase as another system approaches. Rain showers could begin developing during the afternoon, especially after about 2 p.m., and continue into Sunday evening. It will remain cool, with highs generally in the lower to middle 60s. So for weekend plans, Saturday is looking like the better outdoor day, while you’ll want to keep the umbrella nearby Sunday afternoon.
