A strong trough exiting the Rockies lead to explosive development of surface low pressure during the day Wednesday February 11th. At dawn, low pressure near 998 mb formed over southern Missouri. This cyclone deepened to 986 mb as it crossed into southern Michigan by late evening. The cyclone brought widespread high winds stretching from Tennessee through Michigan.
Convective showers along an occluded front crossed central Kentucky during the afternoon. This line brought widespread severe wind gusts 55 to 65 mph along and south of the Bluegrass Parkway. Behind this front, gradient winds increased to 35 to 40 mph...with gusts up to 65 mph during the late afternoon and early evening. Scattered structural damage, tree damage and power outages resulted from both the winds associated with the convection and from the gradient winds outside of precipitation areas.
