Yesterday’s storm event brought (as of this writing) 10 confirmed tornadoes across the Midwest in a wildly off-calendar event. Tornadoes occurred in and just outside of the Chicago metro area, with initial supercells and a QLCS-like storm evolution into the night.

These storms formed just ahead of a surface low pressure/triple point and moved east along a war frontal zone. This helped them acquire enough rotation to produce a handful of damaging tornadoes. Honestly, this event was quite unique in many ways and is yet another off-calendar event to mark 2024 thus far.

Illinois currently has more tornadoes than Texas, Arkansas, Louisiana, and Mississippi in 2024 up to this point.
