A relatively strong area of low pressure moved through the region during the evening of February 18th and into the overnight hours. Widespread convection with some severe storms and areas of heavy rain accompanied this low pressure system.  Convection was aided by very strong wind shear and strong winds just above the surface (around 40-45 knots at 1500-2000 ft AGL).  Although instability was minimal, it was still sufficient for some storms to produce severe wind gusts at the surface.  In addition, some training of storms occurred with very heavy rainfall amounts in just a few hours.  As a result, flash flooding occurred over portions of the eastern Florida panhandle.
