Cold Funnel Sets off Tornado Sirens

Tornado sirens sounded across campus and Porter County last Tuesday, leaving many people confused, as it was partly sunny in most locations. What was the reason for the sirens going off? A cold-air funnel cloud. Best described as an extremely weak funnel cloud, cold air funnels rarely make contact with the ground. They are called cold-air funnels because of the conditions that they form under (namely relatively colder air conditions).
