I've heard a lot of complaints around here about closing schools today because of the cold weather. But when it is -30°F (-34.4°C) outside and you have to wait for the bus, it can be a dangerous situation. I think we can all agree that one day of school is not worth the risk. The chickadees and other birds outside are doing just fine this morning. I don't think a child would do as well.
I took this photograph sometime between 6 AM and 7:30 AM this morning. The thermometer is on our southeast window. The temperature jumped at 7:30 AM when the sun hit it. This is the coldest temperature I have registered at the house in 10 years. I don't know whether it is a record breaking temperature for Barton or not. But on January 24, 1907 a record low of -34°F (-36.7°C) was recorded in St. Johnsbury.
Of mathematical interest: -40°F and -40°C are identical thermometer readings for air temperature. It is the only time that the two temperature scales correlate.
Stay warm out there!
