It's cold out there

Forensic graph from the National Weather Service.
The National Weather Service records the temperature hourly. Their forensic record for Sacramento shows the subfreezing temperatures that many homeless folk sleeping outside have to deal with.

The red line in the graph, at right, shows hourly temperatures measured at Sacramento Executive Airport over a seven-day period.  As you can see, for the past five nights, the red line touches or nearly touches the gray horizontal line that represents a temperature reading of 30 degrees Fahrenheit.

Indeed, each night there are recorded subfreezing temperature readings.  It's cold out there, often windy, but mostly dry with frost on the grass visible at dawn.  Stay well out there, homeless friends.
