Long Island should receive just 1 to 3 inches of snow overnight and into Monday morning, forecasters said as they downgraded earlier predictions that called for up to 6 inches.

Most of the snowfall will come after in Monday's early morning hours and into midmorning, Joey Picca, a meteorologist with the National Weather Services in Upton, said.

Picca said Monday's snowfall should start tapering off "as we get late into the [morning] commute," with temperatures forecast to be in the lower 20s and dropping to the teens and single digits by nightfall.

"We'll see snowfall totals ranging 1 to 3 inches across the Island," Picca said. "Most places will experience 2 inches on average.

Because the accumulation total was downgraded, a winter weather advisory from the weather service was canceled about 9:30 p.m. Sunday

While initial forecasts called for 2 to 6 inches of snow on Monday, low pressure waves along a cold front are moving the snow south and east, the service said, resulting in less snowfall than had been expected this week on Long Island.

Cold temperatures will continue Tuesday and Wednesday, with highs in the 20s both days, and then a slight warming on Thursday with a high in the lower 30s. There is a chance for light snow Thursday night and Friday, the weather service said.
