Overview
Radar
|
6-hour radar loop (4 PM - 10 PM). Storms after 10 PM were sub-severe. |
Environment
 |
 |
 |
| Convective Available Potential Energy (CAPE), or a measure of "fuel" for thunderstorms at 5 PM. Values above 4,000 J/kg are supportive of explosive thunderstorm development. | Wind shear, or change of wind direction and speed from the surface to about 20,000 feet. Values are generally below 30 knots which is not particularly supportive of supercell (rotating) storms. | Microburst composite parameter, which highlights regions favorable for intense microbursts/downbursts. Values were exceptionally high over northern and central Illinois. |
