The National Weather Service in Lincoln reported Tuesday afternoon that conditions are ripe for funnel clouds to form over parts of central Illinois, but that actual touch downs are probably not likely.
A few funnel clouds are possible today. With the remnants of Hurricane Barry directly overhead, a few funnel clouds are possible beneath developing rain showers this afternoon. Touchdowns are not anticipated. #ilwx— NWS Lincoln IL (@NWSLincolnIL) July 16, 2019
In issuing an advisory, the NWS said the current atmosphere could “favor the possible formation of weak circulations” with some circulation “occurring underneath developing showers, where a funnel cloud may develop.” However, once the rain begins, any funnel cloud would dissipate, the NWS said.
“Low-hanging clouds can also appear to dip up and down at times, but they will not show signs of any rapid rotations,” the NWS said, adding that “an actual funnel cloud will exhibit spinning in a counter-clockwise direction.”
The NWS said in “rare instances” the funnels may briefly touch down, adding that residents should “stay alert and be prepared to move to a safe shelter if a funnel cloud approaches the ground.”
Tuesday’s high temperature in the Bloomington-Normal area is expected to be in the mid-80s. By Wednesday and through the remainder of the week highs are expected in mid to upper 90s.
