You may have to go outside to ensure you are comfortable, healthy, and safe inside. The winter storm could dump as much as a foot of snow across Door and Kewaunee counties, and snow drifts could be even higher with the accompanying winds. Overnight low temperatures are also expected to struggle to get out of the single digits from Friday to Tuesday. Ultimate Air owner Jeff Blemke says making sure your filters are clean and your vents are clear are just two ways to ensure your air quality and indoor temperature stay where they need to be.

Blemke also recommends making sure your furnace is maintained to make sure it is operating correctly. Gibraltar Fire Chief Andy Bertges said earlier this week that they have already encountered several carbon monoxide calls due to malfunctioning furnaces this winter.
