No tornado warnings or watches have been issued for the Chicago area, but the National Weather Service said conditions are favorable for funnel clouds to develop this evening, though likely no tornadoes.
In a “Special Weather Statement” issued about 4 p.m., the weather service said “Atmospheric conditions are favorable for development of funnel clouds. These funnel clouds may protrude a few hundred feet downward from the parent cloud.”
While the clouds can “rotate or spin like top” they will last only a few moments and the condition they develop in “do not support strong, damaging tornadoes,” the weather service said.
However, some could touch the ground briefly and produce “very minimal, if any, damage.”
The weather statement is in effect through this evening through much of north and north central Illinois, including Cook, DuPage, Kane, Lake, McHenry and Will counties in Illinois; and Lake, Porter, Newton and Jasper counties in Indiana.
One short tornado warming was issued in Lee County, west of DeKalb and south of Rockford, from 5:15-5:30 p.m. after the weather service got reports of a storm capable of producing a tornado about 9 miles northwest of Paw Paw, and 12 miles south of Rochelle, moving south at 10 mph.
While the conditions may not favor tornadoes, the area may not be totally out of the woods, as the weather services is calling for a chance of thunderstorms, some capable of bringing gusty winds and brief heavy downpours.
That will continue overnight Monday and through Tuesday night, with continued storminess possible Wednesday and into Thursday.
Minor and moderate flooding will continue on portions of the Iroquois, Kankakee and Illinois rivers as more rain falls.
