Temperatures on Monday, Tuesday and possibly Wednesday could prove to Long Islanders that spring really is here, bringing, as well, the possibility of April showers, the National Weather Service says.
There's a slight chance of thunderstorms overnight, and fog may creep in around midnight, but will dissipate by the morning commute, he said.
Monday's high wasn't even close to striking distance of the Island's record for April 8 -- 84 degrees in 1991, Layer said -- but Tuesday may be a different matter.
Expected highs in the mid-70s Tuesday means there's "a pretty good chance" of breaking Islip's record of 73 degrees set in 1991, said meteorologist Lauren Nash at the service. South Shore temperatures are expected to be a few degrees lower, with the North and South forks as much as 5 to 10 degrees cooler, she said.
Assuming an east-moving cold front stays to the north, Wednesday's temperatures also could hit the low- to mid-70s, with cooler temperatures again on the South Shore and Twin Forks, Nash said.
As the cold front sinks to the south Wednesday night, Thursday's temperatures will sink as well, to around 60 degrees, she said.
As for the week's precipitation, there's "an unsettled pattern," she said, with about a 30 percent chance of light rain showers starting around midnight Monday into Tuesday morning, with "a slight chance" of a rumble of thunder.
Wednesday, too, has a 30 percent chance of light rain showers from morning to evening, with a similar slight chance of isolated thunder in the afternoon, she said. Again, there's a chance of light rain showers Wednesday night into Thursday, she said.
