A strong cold front slowly passed through the area on the 10th. Plenty of moisture from the Gulf of Mexico and Atlantic Ocean were drawn into the region ahead of the front. A warm and moist southerly flow ahead of the front caused limited instability to develop. Strong lift from the front combined with the instability to trigger showers and thunderstorms.
Winds just a few thousand feet above the surface were quite strong. Some thunderstorms were able to transport these winds down to the surface during the afternoon and evening hours of the 10th. There was also enough rotation at the lower levels of the atmosphere for isolated tornadoes in the stronger thunderstorms.
