After up to four inches of snow blanketed Long Island on Saturday, Sunday will be mostly sunny and dry, kicking off a week that will be bright and cold.

Temperatures on Sunday will reach a high of 41 degrees, according to the National Weather Service in Islip. Sunday night will be partly cloudy with a low of around 21 degrees.

The Martin Luther King Jr. Day holiday on Monday will be sunny as well, with a high near 32 degrees, although chills brought by gusty winds could make it feel as much as 20 degrees colder.

“It looks like fair weather, kinda on the cold side,” Bill Goodman, a meteorologist with the weather service in Upton, said Saturday night.

Tuesday will again be sunny with a high near 30 and a low around 21 degrees, the weather service said. The weather on Wednesday will be a little warmer, with a high of 36 and a low of 26 degrees at night.

Temperatures will climb Thursday to 42 degrees and then drop to around 30 degrees at night. Friday will see a high of nearly 45 and a low of 34 degrees.

Snowflakes started falling in New York City and Nassau County early Saturday afternoon, causing minor chaos on some local roadways and minor systemwide delays on the Long Island Rail Road. 

Suffolk County police said they saw a spike in crashes as the snow arrived, but they reported no serious injuries. In a tweet later in the afternoon, they urged drivers "to stay home if possible and use extreme caution when on the roads."

There were reports of multiple crashes in Nassau County as well.

The LIRR issued a statement shortly before 2:30 p.m. Saturday saying that it was experiencing 5- to 10-minute scattered systemwide delays due to the weather.

The weather service had issued a hazardous-weather advisory for Long Island that ran from 10 a.m. Saturday to 1 a.m. Sunday.
