What
Temperatures of 33 to 36 degrees will result in frost formation.
Impacts
Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered.
Precautionary actions
Take steps now to protect tender outdoor plants from the cold.

What this week’s weather means for heating, cooling, pipes and fresh air.

Heating this week

About 72% less heating than a typical week.

This week 32Typical 115

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 20
h below 17°F: 0
h below 5°F: 0

47, 17 and 5°F are the test points heat pumps are rated at. About 10 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 31°F). Indoor air will run dry too — a humidifier keeping indoor relative humidity in the 30–50% range is more comfortable and cuts static shocks, without going so high it fogs cold windows.

Open the windows?

Today, 3:00 PM–4:00 PM
