MIAMI -

On this date, a massive arctic air mass over Alaska dropped temperatures in the state to as low as -75 degrees on this date in 1989. As this air mass began moving towards the continental United States, warm air was pushed ahead of it, causing a balmy temperature reading of 62 degrees in Great Falls, Mont. As the front pushed through the upper Midwest, wind gusts of up to 124 mph were reported in Choteau, Minn.
