OK, so that two feet of snow we were preparing to get last night?

Better add another foot to that.

The National Weather Service on Friday morning adjusted its predicted snowfall totals to three feet.

The timing of the snowfall is roughly the same: with light snow falling in Middlesex, Worcester and Norfolk counties Friday morning, and becoming heavy later in the afternoon and into the Friday evening commute.

So, as WHDH meteorologist Jeremy Reiner notes in his blog, you have a "few hours left this morning" to run some errands, but travel will deteriorate this afternoon. By 7 p.m. tonight, most towns will have 2 to 4 inches, Reiner predicted.

The storm should be the worst from 7 p.m. Friday to noon tomorrow, when snow could fall at a rate of 2 to 3 inches per hour.
