The National Weather Service has issued a winter storm warning for most of Massachusetts due to a storm that would dump up to 8 inches of snow across Massachusetts this weekend.

A Winter Storm Warning was issued at about 3 a.m. Saturday and is in effect until 8 p.m. for Brown, Kewaunee and Shawano counties. The weather service shows a band of heavy snow along the State 29 corridor. Areas just north of that corridor and to the south of it are expected to get 4 to 6 inches.

The map I’ve put together for snowfall totals has a fairly wide range of 4 to 8 inches. During Saturday, after we get even more information, I’ll try to start honing that down to see whether we’re going to be closer to the 4 inches or closer to 8 inches.
