This week’s weather will bounce around in normal ranges, switching from sun on Sunday to midweek rain to possible snow on Friday.
Thermometer-watchers will find Sunday and Monday pretty close to average, with temperatures hovering in the low 50s, though overnight lows will retreat to the 30s, forecasters said.
Sun lovers might prefer Sunday, which will be sunnier than Monday, said Faye Morrone, a meteorologist with the National Weather Service in Upton.
Tuesday has a 40 percent chance of afternoon rain that could last until Wednesday afternoon, she said.
The high on Tuesday could climb to just two degrees shy of 60; Wednesday’s high should slip to 52. Thursday is even cooler with a high of around 43 degrees.
While it might seem like the Island has had fewer autumn rains than usual, Morrone said that Islip, its measuring site, has registered about 2 inches more than average, for a total of 12.9 inches.
Temperatures this September to November have run about 3.7 degrees above average, according to the weather service. Experts said that is one reason Long Islanders have seen lots of brown leaves instead of yellows, oranges and crimsons.
Snow lovers might take a bit of hope from Friday’s forecast; there is a 30 percent chance of precipitation, though rain could fall instead, the weather service said.
The high might hit 44 degrees; the nighttime low just 34.
