Not at all too early to think about the warmest Fall ever (SON). If Oct. finishes near +7.5degs. and is combined with Sept.'s +2.5degs., I estimate Nov. need only be about +3degs. to set a new Fall warmth record.
Record now [SON} is 61.8degs.--- in 2015. Normal for [SON] is 57.5degs. Difference to set a new record would thus be +4.4degs.
Sept. contributes 0.82, Oct. (estimated) will contribute 2.60, and Nov. would be contributing about 1.00, so it needs to end up near +3.0degs. or better.
