The National Weather Service on Sunday issued a hazardous weather warning for most of Long Island, with sleet and up to once inch of snow expected to coat the region overnight.
According to David Stark, meteorologist with the National Weather Service office in Upton, it is still a little unclear when the rough weather will hit the area.
"We could possibly see some light snow later this afternoon, around 2 or 4 p.m., but nothing steady until the evening. From that point on, it will stay snow for a while before mixing in with some sleet around 8 p.m.," Stark said.
Toward midnight, the precipitation is expected to change over to all rain, Stark said, with rain expected for the Monday morning commute.
Accumulation of up to an inch is expected before the snow turns over to rain, Stark said, adding that Nassau County could see more than that. if the snowfall begins earlier, and with greater intensity, some higher accumulations could be reported.
Temperatures on Sunday hovered in the low 30s but are expected to rise to the 40s after midnight.
"The morning commute will just be wet, no snow," Stark said. Precipitation is expected to taper off Monday, with cooler air moving back into the area later in the day.
