While it may have been fall for some time, finally it's about to feel like it.
After 22 consecutive days of above average temperatures this month, Wednesday breaks the streak with a high of 53 degrees expected at Long Island MacArthur Airport in Ronkonkoma, the National Weather Service said.
That would be below the norm of 61, said Joey Picca, weather service meteorologist based in Upton.
What's more, "below normal looks to be the norm" in the coming days, he said, with a cooler air mass expected to bring highs in the 50s through the weekend.
As of Tuesday, October's average monthly temperature at the airport had been 61.9 degrees, which is 6.3 degrees above normal.
Along with cooler weather comes peak fall foliage on Long Island this weekend, according to a report on ILoveNY.com. That means "a nice mix of orange, yellow and some green leaves" in the Hamptons and "orange, yellow, gold, red and purple leaves of average brilliance" in Nassau and western Suffolk, the report said.
As for lows, most of southern Connecticut is under a frost advisory overnight Wednesday into Thursday, and some areas of Long Island, such as the coldest spots in the pine barrens, could also see frost, Picca said.
With mid-30s forecast for most of Suffolk on Thursday night into Friday and Friday night into Saturday, some spots, similarly, could get cold enough to see frost, he said.
A small amount of rain, less than a 10th of an inch, was likely on Long Island during the day Wednesday, with no significant precipitation on the horizon, the weather service said.
The area has been deemed "abnormally dry" by the National Drought Monitor, with a 2.52-inch rain deficit so far for October, the fourth month in a row to register a deficit of an inch or more.
