Thursday should have rounds of rain and possible thunderstorms before Long Island begins a sunny holiday weekend, forecasters said.
Showers can be expected throughout Thursday, but the line of storms that may be of concern are forecast for later in the afternoon and tonight, said Tim Morrin, National Weather Service meteorologist in Upton.
That means starting primarily between 2 and 4 p.m., with any potentially strong storm starting very late in the afternoon to early evening hours.
According to a hazardous weather outlook, Nassau County is in an area that could potentially see a strong to locally severe storm that could be capable of producing damaging winds and hail.
The day began with showers, said News 12 Long Island meteorologist Rich Hoffman. Otherwise the skies will be mostly cloudy with highs in the upper 60s.
"The second round's coming in this afternoon," Hoffman said. There could be brief heavy rain into the evening and overnight hours as a warm front moves into the region, before a cold front clears away the precipitation with overnight lows in the upper 50s.
Friday ushers in a string of nice spring days. It should be sunny and breezy, with gusts as high as 28 mph and highs in the low 70s.
Memorial Day weekend, the unofficial start of summer, won't feel like it. The days will be mostly sunny and warm but not steaming, and expect it to be cooler at the ocean beaches for events such as the 16th annual Bethpage Air Show at Jones Beach.
Saturday should have highs in the upper 60s with a chance of showers after midnight. Sunday should have highs in the upper 70s, closer to summery.
"Sunday will be the warmer day," Hoffman said.
Monday, Memorial Day, should be mostly sunny again with highs in the mid-70s.
