Rainfall Soaks the Southeast

Bookmark and Share

Last night was quite the show by mother nature.  There were hailstones as big as 2" reported in Hutchinson County and even reports of a trailer tipped over by the wind.  Below are the numbers as reported by the National Weather Service, remember for some this a month's worth of rain!

Estimates are given by both observations made by rainguages, weather offices, aviation centers, and even by radar.  The following collection is 24-Hour observed rainfall amounts as of 10:00 a.m. Sunday, 8/11/13.

First, the MN rainfall amounts:

Here are some observations from SD:

And finally some IA amounts:

Some remote areas most likely saw higher amounts, but rain measuring devices are scattered and quite far apart out in the rural areas.  That's why we use radar estimates at times to get a feeling of what amount fell over sparse areas.  Here's a look at what radar is estimating for rainfall, I have placed a circle over Sioux Falls for a landmark:

Let's take a look of why such huge rainfall amounts occured, many of us were sleeping so the large amouts of standing water outside in the morning was probably surprising.  Here's an image at around 10:00 p.m. local time.  You can see 3 distinct waves of very heavy rainfall, and they weren't flying by either, traveling to the SE around 30 mph.  Besides the threat of hail from the cells earlier in the evening, they were not severe as they passed I-29.

Either way, the southeast parts of SD needed that rain, we haven't had much this summer, and the soil was past due for such a rainfall.  Sioux Falls had only seen 1.12" of rain since July 1st before yesterday.
