The cold temperature and even rain will continue Friday afternoon, May 16, along with a chance of cold air funnels in some areas, according to the National Weather Service.
The weather service said isolated thunderstorms and flooding in some areas is possible in north central Indiana. Cities including Monticello, Peru, Wabash and the surrounding counties may also see small hail, brief heavy rain and cold air funnels.
According to the National Weather Service website, cold air funnels usually happen when showers develop in the vicinity of an upper low and very cold air aloft.
The weather service will not issue a tornado warning for a cold air funnel, partly because they rarely touch down and are nearly impossible to detect on radar.
If a tornado does touch down, it will produce winds similar to a weak tornado.
“If a cold air funnel is spotted, take the same precautions you would for any funnel cloud or tornado,” the weather service said in a statement.
Although areas in southwest Michigan and northern Indiana, including Elkhart, St. Joseph and Marshall counties, are not expected to see cold air funnels Friday, they may expect to see significant rises in water levels of rivers and streams. Patchy frost is also possible late Friday night, according to the weather service.
