As the low reached its peak intensity over north central Minnesota late in the day on October 26th, the pressure gradient increased across the southern and eastern parts of our area. Winds are driven by differences in air pressure. Therefore, strong winds - generally from a westerly direction - developed in the afternoon and evening of October 26th. Some of the gusts were very strong. We had 15 different sites report wind gusts in excess of 50 mph. The strongest gust was 65 mph on the Blatnik Bridge that connects Duluth and Superior. It should be noted that the bridge rises about 100 feet above the water, and the increased elevation of the instrument likely contributed to stronger winds at that particular location.
