In the wake of a winter storm system which brought about 4 to 12 inches of snow over parts of central, east central and southeast Illinois on Sunday, brutally cold weather will prevail over much of the Midwest. As blustery northwest winds continue through much of the period, wind chills will fall to exceptionally low levels for this area. Wind chills by this morning will range from 30 below zero to near 50 below zero at times. These dangerously cold wind chills will persist through Tuesday.
Such cold weather will be threatening to life and property. It is best to remain inside as much as possible during this cold snap. If you must be outside, dress warmly in multiple layers, and limit the amount of exposed skin. Frostbite can occur in as little as 10 minutes, and hypothermia (body temperature of less than 95 degrees) will be a serious threat for people that must be outside for an extended period of time. Should your furnace fail, do NOT use ovens or outdoor grills to warm your home, as they can cause carbon monoxide poisoning or fires. Go to a friend or family member's home, or check with your local municipality to see if they have warming shelters established. Be sure to know how to turn off your water supply should the pipes burst. Animals should be brought to an indoor shelter.
