What had been forecast to be a moderate winter storm for Tewksbury and the Merrimack Valley is beginning to pickup momentum and could wind up packing a pretty good wallop.
The latest forecast from the National Weather Service is now calling for Tewksbury and the surrounding area to get 6-8 inches of snow.
Snow is expected to continue through the night and a Winter Storm Warning remains in effect until Sunday at 7 a.m.
Visibility on the roads is limited and fog is expected to roll in around midnight to 2 a.m. making it worse. The low temperature tonight will be around 26 degrees. There will also be steady North winds overnight from 10 to 13 mph.
