Rochester, Minnesota

We are going to sneak close to home tonight, going down to Rochester, the home of the Mayo Clinic.

At 1254AM, CT, Rochester was reporting a temperature of 67 degrees with fair skies. Low pressure moving through northern Manitoba is inducing a lot of low level moisture northward, and dewpoints across the region were high. Fog is likely to settle in in low lying areas overnight, particularly given the clear skies.
Between the low in Manitoba and the remnants of a system in northern Quebec, there has been a rise in instability in the Upper Midwest, with scattered showers through Wisconsin on Saturday. The Manitoban low will bring some drier air into northern Minnesota on Sunday, and continue through the southern part of the state on Monday. As a result, shower and storm activity will become more voluminous, and depending on the available energy, there is a chance for some severe weather in the Rochester area on Monday.

The timing everyone has for precipitation is all different. Several outlets have rain starting shortly after midnight on Monday, while others don’t have it until the evening. Meanwhile, we have a chance on Sunday. Here is a loop of the day’s satellite imagery, showing the thunderstorms moving through Wisconsin, and fog developing up by Duluth.
