Typically, strong <br />regional winds aloft with these <br />systems prevent thunderstorms from <br />training and ensure that precipitation <br />is not prolonged. Thus, the highest <br />precipitation total is usually kept <br />below 2 inches. In this case however, <br />numerous clusters of thunderstorms <br />formed just east of the advancing low <br />center, producing widespread heavy <br />rainfall. As the cyclone reached peak <br />intensity, its forward motion slowed <br />dramatically, and heavy stratiform <br />precipitation (eventually changing to <br />heavy snow) impacted many of the <br />same areas that received repetitive <br />thunderstorms. Portions of northeast <br />Minnesota received over four inches <br />Rainfall associated with October 25-27 non -convective high wind event. <br />Courtesy NWS Duluth. <br />197 <br />
