Although we struggled through a very dry period extending into early August, there has been considerable, beneficial precipitation in portions of Minnesota. Dr. Seeley alluded to the moisture in his blog on Friday.
The image above is the weekly accumulation as estimated by Doppler radar ending on Saturday, August 22nd. You will recall the five to nearly seven inches of rain that fell in portions of the south and west Metro the previous Friday and Saturday, August 14th and 15th, prior to the PGA at Hazeltine.
So far in August, the Chanhassen National Weather Service rain gauge has collected nearly seven and three quarter inches of rainfall.
I’m watching a pooling of high dew points in central Minnesota that could be the focus to fire up thunderstorms later today from about Bemidji to Marshall. A cold front will be knifing through the state tonight and early Tuesday. Some thunderstorms could become severe.
