Schools are closing or operating remotely and warming shelters are opening their doors as temperatures in Northwest Indiana are expected to plunge into the negative single digits Friday and wind chills as low as -28 are predicted, according to the National Weather Service.
A collapsing polar vortex is expected to bring high winds, a chance of snow and freezing temperatures through the weekend as dangerously frigid air from Siberia and the North Pole is expected to dip the Great Lakes into subzero territory.

“A piece of (the polar vortex) will break off and meander southward into our area,” said Gino Izzi, a senior meteorologist with the National Weather Service.
The National Weather Service has issued a cold weather advisory from 3 a.m. Friday until 9 a.m. Saturday for Northwest Indiana.
A polar vortex is a constant cold, low-pressure system of air that circulates counterclockwise around both of the Earth’s poles, acting like a wall that contains cold air. A jet stream is a band of strong wind that generally travels from west to east and acts as a boundary between cold, polar air and warmer air farther south. A weak polar vortex can cause the jet stream to buckle, sending Arctic air from the North Pole southward, according to NWS.
When a polar vortex collapsed in 2014 and brought dramatic subzero arctic air and windchills to the Midwest, Izzi said many Chicagoans started loosely referring to other severe winter storms as “polar vortexes.” This time it’s not expected to be as severe as in 2014 when that vortex was centered directly over the Great Lakes; this year it is farther north over Canada.
This winter may also be less predictable due to a weak La Niña year.
La Niña is a climate pattern of cooler-than-average ocean temperatures in the Pacific Ocean that can affect weather worldwide, according to the National Oceanic and Atmospheric Administration. During a La Niña year, cooler-than-average global ocean temperatures bring cold weather to the Midwest and Great Lakes. But La Niña weather conditions are also highly variable, Izzi said.
Indiana state agencies recommend the following precautions if you must leave your house in hazardous conditions: Slow down and adjust your speed to road conditions, especially in snow; Check conditions and forecasts before you hit the road; Allow plenty of time to reach your destination safely; Never tailgate or drive beside a snowplow; Leave extra space between your vehicle and the one in front of you; Prepare an emergency kit with snacks, water, a phone charger, sand or cat litter, flares or bright LED alternatives, a flashlight, and blankets or extra clothing; Keep your vehicle full of gas and check your battery, fluids and spare tire; and Clear all snow and ice from your vehicle’s windows, lights, and signals.

Safety tips
NIPSCO advises residents to clear snow and ice from intake and exhaust vents, which can help avoid carbon monoxide buildup and help appliances operate well. Space heaters, which are a source of winter home fires, should be used with caution, on hard surfaces and anything flammable should be at least three feet away. Do not burn charcoal or run a generator indoors. Never use a stove or oven as a source of heat. Meters should be clear and visible in case maintenance is required.
Frozen pipes can cause pipes to burst during extreme cold events. Let faucets drip, especially those adjacent to an exterior wall, according to the American Red Cross.
Chimneys should be cleaned and checked for blockage at least once a year before using your fireplace, NIPSCO stated in a rellease
If you smell any “rotten egg” odor of natural gas or think there may be a gas leak, stop what you are doing, leave the area immediately, and then call 911 and the NIPSCO emergency line at 1-800-634-3524. Symptoms of carbon monoxide poisoning can include headaches, dizziness, nausea, vomiting, irregular breathing, and feeling ill or tired while at home, but fine when away.
