The cumulative anomaly for 2015 thus declines from -18.2 to -17.1 degrees F.
That's now two months in a row with above average temperatures, helping to erase the big negative anomaly built up in the winter, and in February in particular.
Summer temperatures in GR in 2015 were below normal, so the warmer September and now October have offset that. A late or extended summer, you might say.
The cumulative anomaly in 2014 was -30.3 degrees F, and would have been even worse if not for a warm and snowless December. November set snow records here with 31 inches and the negative temperature anomaly reached -33 degrees F.
The peak negative anomaly in 2015 so far has been -22.6 degrees F through August.
