Multiple Mesolows over Lake Superior on 2/17

Light winds and cold temperatures inland allowed for the formation of meso-lows on Lake Superior. These features are small low pressure systems that form due to converging winds over the relatively warm open waters. Land breezes off of Ontario and Upper Michigan focused winds toward eastern Lake Superior. Because of the concave curvature of the northern and eastern shores of Lake Superior, the winds converged in the middle of the lake and developed "spin" in the low-levels of the atmosphere.
