A broken line of thunderstorms intensified as it raced east-northeast, causing several locally damaging wind events. The storms were associated with a compact 500 mb shortwave trough and related jet streak that raced northeast from the southern Plains.  Within the warm sector of the surface low, a low-topped broken line of thunderstorms advanced northeast across southern Illinois. Unseasonably warm surface temperatures in the lower 70's and surface dew points in the lower 60's contributed to a modest diurnal uptick in intensity related to afternoon heating.

A vigorous upper level system passed over the southern Great Plains on Sunday February 26th, 2023. This brought widespread strong winds and blowing dust to the Panhandles, particularly during the late afternoon and evening hours as a Pacific cold front rapidly moved eastward, with the large amount of dust leading to greatly reduced visibility and treacherous driving conditions. This coupled with ongoing drought conditions and low relative humidity values lead to a couple of wildfires, one of which burned over 5000 acres (Big Fin Flats Fire).
