The rain itself otherwise had a marginal <br />impact (no significant flooding, no damage), and although severe weather was reported well to <br />the south of the region, no other significant hazards preceded or followed the extraordinary winds <br />in Minnesota and the Upper Midwest. <br />On November 10,1998, <br />An explosively intensifying low pressure system tracked from Kansas to western Lake Superior, <br />producing a wide array of dangerous weather conditions, punctuated by a deadly, long-lasting <br />bout of non -convective extreme winds. The storm set the statewide low-pressure record (at the <br />time), with 962.7 millibars registered at both Albert Lea and Austin. <br />Although most of Minnesota had widespread 30-50 mph winds, with gusts up to 75 mph, the most <br />devastating winds stretched from central Iowa, through the majority of Wisconsin, and into Upper <br />and western Michigan. These areas experienced up to 18 hours of sustained 35-50 mph winds <br />with frequent gusts of 65-75 mph, and many gusts exceeding 85 mph, including a 93-mph gust <br />recorded at the La Crosse NWS office. Wind gusts exceeded 85 mph over far southeastern <br />Minnesota. <br />193 <br />
