our local cold weather

[hastings37]

Amazingly difficult to find actual local temperature data for West Roxbury from this frigid Sunday morning!

But the government offers a few days of good recent data for East Milton:
http://w1.weather.gov/data/obhistory/KMQE.html

They have it in the single digits Friday and Saturday, then around -5 from midnight until 9am this morn, with a lowest of -7 at 7am. Could well be a record for that date?

Best hyper-local data for West Roxbury would be
Arnold Arboretum - Roslindale, MA > 42.295 -71.134 > 148 ft
located at the new research facility building?
*** lowest -5F from 5am to 7am ***

There does not seem to be any "official" weather data for West Roxbury.

But there are some "personal weather stations" data online:
