A special weather statement warning of black ice, especially on untreated surfaces, expired at 3 p.m. Tuesday, the National Weather service said. The statement had been in effect for the morning commute and into the afternoon, with Long Island temperatures Tuesday in the mid- to upper 20s.
After a rainy Monday, a blast overnight of arctic air swept into Nassau and Suffolk counties, keeping temperatures in the 20s and allowing any patches of black ice to persist, the service said in its statement. Two cold fronts are expected to bring a stretch of mostly clear skies and daily highs in the mid-30s for the rest of the week, the service said.
There's only a slight chance of snow flurries Wednesday from around 4 a.m. to 2 p.m., but the service said any accumulation would likely be negligible.
The first cold front, which is expected to pass south of Long Island on Tuesday, will generate high pressure up north that will remain in the area through Thursday.
Then a second cold front crosses the area Friday, creating a second high-pressure buildup and mostly clear conditions.
Daily highs Saturday and Sunday should be in the mid- to high 30s, the service said.
