Heavy amounts of rain, generally between 3 and 5 inches, fell in a swath stretching from Liberty county eastward through Tallahassee and into Madison county.  This event was enhanced by a passing shortwave interacting with an elevated warm front and a relatively strong low-level easterly jet.  Elevated convection developed along a line parallel to the mean storm motion, causing the line to train over the same areas and produce heavy rain.  Given the recent severe to extreme drought conditions in the area, flooding was limited to minor urban flooding around the city of Tallahassee.  One large tree also fell on a home in Tallahassee, due primarily to heavy rainfall weakening the root system of the tree.  All recorded wind gusts in the area were under 30 mph and the atmospheric setup was not favorable for severe winds to reach the surface.

WCTV reported that a large Red Oak tree greater than 100 feet tall fell onto a house on Sedona Road in Tallahassee around 3 am EST.  The peak wind gust measured about 6 miles away on the Florida State University campus around that time was 28 mph.  No other wind gusts higher than 28 mph were measured anywhere in the area.  It is believed that heavy rainfall of 3 to 5 inches weakened the tree root system, and a wind gust near 30 mph pushed it over onto the house.  No other reports of trees falling over or any other damage occurring elsewhere in the area were received.  WCTV reported that the cost to remove the tree from the house was about 5,000 dollars.  In addition to the tree removal, major roof damage occurred to the house with some water damage inside.  The damage to the house itself was estimated.  There were no injuries inside of the house.
