After a snow surprise -- a quick-moving band that dropped as much as 2 inches in about two hours -- slipped across Long Island on Friday, dry conditions settle in for most of the weekend, the National Weather Service said.
Snow fell from west to east across Nassau and Suffolk counties, mostly between 7 a.m. and 1 p.m., the service's Upton office said, with a few reports of accumulations of 2 inches.
The snow caused some slippery roadways and low visibility, with winds gusting between 25 and 35 mph, but the state Department of Transportation's website reported no major accidents on Long Island parkways or highways during the morning commute.
Adrienne Leptich, a meteorologist at Upton, said that Levittown had the highest Nassau total during the rapid-fire snowfall, with 2.1 inches; in Suffolk, Melville got 2 inches.
By 1 p.m., the band had slithered off the East End and into the Atlantic, the service said.
Originally, the service had predicted the band to deliver about a half-inch maximum during the its trek from west to east.
"These bands just form and sometimes they are difficult to predict," Leptich said. "Sometimes it can deliver more than we anticipate."
The good news is that the rest of the weekend, until Sunday night, is likely to be dry and not nearly as cold as the past week, the service said.
Cold, yes. But not as frigid as the past several days, when it felt as if Long Island had been transported to the Arctic Circle.
Friday night sees gradually clearing conditions with a low of 16. Saturday calls for mostly sunshine, with daytime highs in the low 20s.
By Sunday, the temperature climbs to the mid 30s during the day and winds from the southwest subside to between 5 and 11 mph.
There's a slight chance of a wintry mix Sunday night into Monday morning, and Leptich said that precipitation could have an impact on Monday morning's commute.
Chance of precipitation ranges from 20 percent Sunday night to 50 percent Monday morning.
