What this week’s weather means for heating, cooling, pipes and fresh air.
Tonight’s low: 24°−4°
Overnight low near 24°F — not yet at drip-the-faucets cold, but worth watching if it's forecast to drop further.
About 63% less heating than a typical week.
Heating degree days, base 65°F
47, 17 and 5°F are the test points heat pumps are rated at. About 19 hours are near freezing and damp, when outdoor units defrost more often.
Dry air outside (dew point 27°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.
No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
Today’s expected high is 3°2° colder than typical.
On average 3°1° colder than normal (daily mean temperature).
