Long Island Weather: Snow, Sleet For Saturday

A winter weather advisory will be in effect for Long Island from 7 p.m. Friday until noon Saturday.

Nassau County and northwestern Suffolk County will likely see 2-4 inches of snow, with the highest amounts expected farther west and closer to the north shore, according to the National Weather Service. The rest of Suffolk County will likely see 1-3 inches. Once again, the highest amounts are expected closer to the North Shore.

Sleet will likely mix with the snow overnight. Plan on slippery road conditions, the NWS says.

Another storm Sunday night into early Monday has the potential to bring several more inches of snow and sleet, but that forecast remains uncertain, the NWS says.

Next week, temperatures will be well below normal for early March, by as much as 10 to 15 degrees.
