WEATHER ALERT DAY: Dangerously cold for another morning TUESDAY MORNING UPDATE: Try to avoid being on the roads, as conditions will struggle to improve and temperatures will be dangerously cold. If you need to venture out, know what you're going to do in case you slide off. Be prepared to survive the elements until help arrives. The ABC 17 Stormtrack Weather Team has issued a Weather Alert Day with another round of snow and dangerously cold temperatures Monday and Monday night. Frostbite can occur in less than 30 minutes as cold as it will be. SYNOPSIS The Arctic air that invaded last weekend is getting some help. The Tropospheric Polar Vortex that keeps Polar air locked up around the Arctic Circle broke down last weekend and is going to rotate down some more of it. When the area of low pressure holding back the Arctic Air breaks down, that opens the gates for that air to move south.
