Deck thermometer currently shows 4°... check the timestamp... should keep dropping until sunrise... at which point, Sol and the predicted southwesterly winds should pump up the external temp to a sufficiently balmy 27(+?) degrees tomorrow afternoon.
I am loving this... Have the last vestiges of the evening fire going... toasty 77° downstairs... 61° up here, but I just cranked the heat... hoping to hit 64° before I disrobe for bed.
