Forensic graph from the National Weather Service. |
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.
