I put in a request from NOAA's National Center for Environmental Information (NCEI) for maximum temps at Randolph for 2/6/78 and 2/7/78. They emailed a list of cities in E MA, of which the closest to Randolph was Brockton. The max there was 34F on the 6th and 35F on the 7th. Hingham had a max of 34F on the 6th and 32F on the 7th. By comparison, Boston was 34F on the 6th and 33F on the 7th.
My main point being there was no fluff factor with that snow, limiting the drifting in many areas, despite the strong winds.
