A vigorous upper level disturbance, dropping through the Dakotas, triggered scattered strong to severe thunderstorms from near Sioux Falls, South Dakota through Northern Iowa to near Rochester, Minnesota during the late afternoon on the 13th.  The storms propagated east southeast during the evening.  A small scale bow echo moved into the Waterloo and Marshalltown areas late in the evening on the 13th and weakened, as a gust front, marking the leading edge of cooler and stable air, surged out ahead of the small scale bow echo, choking off the inflow and  weakening the storms.  Additional strong to severe thunderstorms reignited early on the morning of the 14th, near the intersection of the outflow and surface cold front from Waterloo to Dubuque.  The convection blossomed into a Mesoscale Convective System or MCS and tracked through Eastern Iowa producing very heavy rain, large hail and damaging winds.  Lightning and strong winds from the storms knocked out power to some 4,400 homes in the Quad Cities.
