UPDATE FRIDAY, JUNE 24, 2016
National Weather Service survey teams have determined nine tornadoes occurred across north central and northeast Illinois Wednesday evening. These findings are the result of extensive ground damage surveys along three separate supercell paths: Amboy to Sheridan, Troy Grove to Mazon, and Pontiac to Cissna Park.
Tornadoes determined thus far:
- Pontiac: EF-2
- Marseilles to Seneca: EF-2
- Cissna Park: EF-1
- West Brooklyn: EF-1
- Ottawa: EF-1
- Troy Grove: EF-1
- Ottawa 5 NW: EF-1
- Mazon: EF-0
- Sheridan: EF-1
The NWS says ground survey data will be augmented with aerial photography and satellite imagery next to complete the survey documentation process over the next few days as these data sources become available. It is possible minor adjustments to existing tornado paths may take place based on new photographic evidence. It is even possible the number of tornadoes could increase.
Kane County was hit with about an inch to 2 inches of rain, according to the NWS.

We are under a “moderate” severe thunderstorm risk, but don’t let that innocuous-sounding adjective fool you. Moderate is No. 4 on a five-point scale, and it means that wide-spread severe storms are likely, with the potential for strong tornadoes, damaging winds and 2-inch hail.
