Dozens of record lows have been set in the Midwest and Plains since this weekend as the second of two arctic blasts in the past week invaded those regions.In Northern California the temperature dipped into the 40's overnight. That's shirtsleeve weather back East, but cold enough to chill the house to 57 degrees F. this morning.
Actual air temperatures fell into the 20s and 30s below zero, while wind chills plunged into the minus 30s, 40s and even a few 50s at times during the weekend.
I turned up the natural-gas furnace, as, I suspect, did many Sierra Club members. Solar panels just don't produce enough BTU's for comfort.
