Once again, the snow is melting. But once again, don't put the shovels away: the weekend could bring more snow.

A new snowstorm is headed our way for Saturday and Sunday, forecasters say, and Needham could see up to 12 inches of new snow before it's done.

On his blog, WHDH meteorologist Pete Bouchard is calling for light rain along the coast Saturday with snow inland and snow across the region by Sunday morning.

"Heavy snow through early morning Sunday. Roads will be tough to travel, and yes, your flight will most likely be delayed or cancelled. (Although I don't run an airline, so I'll let them have the final word.)," Bouchard writes.

As of now, forecasts call for 8 to 12 inches of new snow in the towns west of Rte. 128.
