Impressive rainfall totals from last Thursday

Two complexes of rain and thunderstorms on Thursday dumped tremendous rainfall amounts across portions of Wisconsin and Minnesota. That morning, the first complex of storms would work through Western Wisconsin. Nothing severe, but the heavy rain was too much for some of the storm drains in Rice Lake. We got several pictures of people paddling on flooded streets in town. Below is a look at rainfall totals for the entire region. Notice the Rice Lake area saw upwards of 3-5 inches of rain.

You'll see down in the Coulee region rainfall totals weren't as impressive. However, the La Crosse area up towards parts of Jackson County did see totals over 1".

What really stands out on this map is that bullseye that's just south of the Twin Cities. Those impressive rainfall totals were from thunderstorms that fired behind that morning round of storms. A warm front laid across the area with plenty of warm, moist air feeding the storms. Upper level winds were supportive of the thunderstorms to "train" over the same areas dumping substantial rains. Here's a zoomed in look below. You can see a decent size swath of rain totals over an 6 inches from Northfield, MN over to Red Wing, MN. Some locations saw over 8 inches of water. Many of these locations were under Flash Flood Warnings. Even extreme western Buffalo County saw some soaking rains. The Hager City area saw totals at least over 5 inches.

All of this rain across the viewing area will make us susceptible to flash flooding in the coming days. There are plenty more chances for thunderstorm complexes like what we saw last Thursday. Check out this estimated rainfall totals expected by the Hydrometeorological Prediction Center for the next 5 days. Pretty much the entire SkyWarn13 viewing area could see at least over 2" of rain while some locations picking up more than 3.5". That could mean more scenes like what happened in Rice Lake on Thursday in the coming days. Heavy rain is likely again tonight, and there is a possibility for some flash flooding.
