In case you thought summer was over already, think again.
Long Island weather is expected to become hot and humid this week, ending a spate of downright autumnal weather that visited the region during the past few days, according to the National Weather Service.
Sunday will be cloudy and cool, with temperatures hovering in the 70s and a chance of light rain or drizzle, said David Stark, meteorologist with the service's Upton bureau. Lows on Sunday will be in the lower 60s.
But Monday temperatures will start reaching into the lower 80s and the cloud cover is expected to give way to sun, Stark said.
"It will definitely feel more summerlike tomorrow," Stark said on Sunday. A shift in a high pressure system, which will bring more warm air from the southern United States, is the culprit. Humidity levels are also slated to rise through the week, Stark said.
Lows on Monday will be in the mid-60s.
Tuesday will warm up even more, with temperatures in the low to mid-80s.
"Tuesday will be one of the warmer days we've seen in the past week," Stark said. Lows on Tuesday will be in the mid- to upper 60s.
Wednesday will also be in the low to mid-80s, with lows in the mid- to upper 60s.
The next chance of precipitation will come on Thursday, with temperatures that day again in the low to mid-80s. A chance of rain will occur late in the day, with lows in the mid- to upper 60s.
A cold front will begin to move in on Friday, pushing temperatures back down into the low 80s.
