A strong cut off low pressure system developed across the Central Plains on Saturday 10/13 and moved into the Upper Midwest on Sunday 10/14. Due to sufficent wind shear, moisture, and a lifting mechanism, this was a good enough setup for severe thunderstorms. The images below show convection beginning around 2pm and blasting through the Chicagoland area over the next couple of hours. Brief heavy downpours and gusty winds were the main issues with this event. The highest wind gust of 65 mph was reported in Peotone, IL.
A TORNADO Warning was issued across northern Cook County and a possible brief touchdown occurred in Schaumburg. Several trees were uprooted and a few roofs were damaged. The National Weather Service is conducting a survey today and an answer will likely be given later today.
Another strong system is forecasted on Wednesday with a few more strong storms possible. This is very typcial during the spring and fall seasons. When seasons make their transition from summer to winter or vice versa, low pressure systems become stronger to due the enhanced jet sreams across the U.S.
