Will Waltham get pummeled this weekend with more than a foot of snow or will it be a half-foot with rain mixed in?
The National Weather Service has issued a Winter Storm Watch from Saturday afternoon through Sunday afternoon. The NWS said 6 inches of snow or more is possible and warned of heavy wet snow that may fall at 1 to 2 inches per hour. Snow may mix with rain in the Waltham area.
The NWS warned that the heavy wet snow could bring down tree limbs and result in scattered power outages.
Channel 7 meteorologist Pete Bouchard wrote on his weather blog:
Storm start-up still looks like Saturday afternoon. We'll still be able to get around and the amounts will be light through midnight - in fact, we may even mix from Boston to the South Shore. (Cape sees rain.)
After midnight, the storm will get a little meatier. Snow intensity will increase into Sunday morning.
Heavy snow through Sunday morning.
Tapering to flurries by mid afternoon on Sunday
There is a lot of water being thrown around in the atmosphere, and with marginally cold temps, this will result in a heavy, wet snow in many spots. Even in Worcester county, it will make for good snowballs and snowpeople. On the South Shore, it will cake to the trees and power lines - so there might be more power outages.
