We’ll need to monitor the evening development of more intense bands of showers and thunderstorms. Those will be the storms that deliver the heaviest rainfall amounts.

So far, the consensus in the models and is reflected in the National Weather Service forecast rain totals, is in southeastern Minnesota. A couple of forecast models are a bit more north, perhaps up to even Northfield or Red Wing.

Unfortunately, we won’t really know until these band start to develop late Friday afternoon and evening.
