Hundreds of millions are under a storm watch as temperatures fall to single digits and below zero. 

The National Weather Service has issued an extreme cold watch with wind chills ranging from 30 to 40 below zero. With brutal cold expected to arrive this weekend, here are a few simple ways to keep the cold outside and the warmth inside. 

First, turn up the thermostat a few degrees to make your home comfortable instead of frigid. Next, walk around your house and check for any drafts. Adding weather stripping or a little caulking around doors and windows can make a big difference. Ensure all your windows are locked tight, and storm windows are properly installed. For extra protection, applying a transparent window film can help trap heat where it belongs. 

And finally, don’t forget the most enjoyable tip: grab a blanket, make some hot cocoa, and cuddle up with someone close to you. It might be the warmest solution this weekend.
