A potent upper level trough as well as a surface cold front crossed the region during the afternoon of March 22nd. Out ahead of the trough, surface heating and cold upper levels were able to generate marginal amounts of surface instability. This was enough to generate scattered showers and a few thunderstorms as the front and trough passed across the area. Steep low level lapse rates and low freezing levels allowed for some of these thunderstorms to produce gusty winds over the waters.
