Storm Track Just North of Area
These rounds of storms usually develop in the evening and use a nocturnal low-level jet stream, ample moisture, and warmth to maintain themselves through the nighttime hours. As meteorologists often say, "they round the ridge." That phrase refers to the areas of storms that develop. Once they do form, they usually congeal into a line and push southeast rapidly -- following the winds of the jet stream aloft. With the jet being just to our north this week, the locations with the best chance of seeing these lines of storms -- or MCS's -- will be Minnesota, northern Iowa, the eastern Dakotas, and Wisconsin. However, as is usually the case with these patterns, the MCS's will tend to have enough strength to push further south than forecast models suggest. That is why there is a chance that we could see some of these nighttime storms reach the region both Tuesday night and Wednesday night.
