HD EXPEDITION VIDEO: Funnel at Mascoutah, IL

I observed two "cold air" funnels over St. Clair County, Illinois (eastern St. Louis metro) after noon today, the second of which persisted over Mascoutah for 14 minutes and made it as close as halfway to the ground:

This was the first funnel observed over Highway 161 west of New Baden:

I also observed stationary "micro" precip cores on the road in the vicinity of the funnel no more than 15 to 20 feet wide:

The funnel appeared between two nearly stationary thunderstorms, both of which appeared to be rooting on a boundary in mean westerly flow aloft.
