Sunday's Rainfall Totals with April-Like Weather on the Way

Another round of very heavy rainfall hit parts of the area Sunday and Sunday night. Storms fired up and started off severe with quarter to half dollar size hail falling in several spots from Sioux City to Canton, but brought 60 to 70 mph winds to Alcester, Akron, Alvord, and Hull, taking down trees and power lines and even blowing a roof off of a business. But after the initial severe weather, storms transitioned to heavy rainmakers, which affected much more of the area, and could have lasting damage to farmers. The highest of the rainfall totals can be seen in the picture on your left where as much as three and a half inches fell. Those that need a break from the rainfall aren’t going to like the forecast as more rain will likely move into the area Wednesday.
Here is a look at the rainfall analysis according to radar estimates. Pretty easy to see where the heaviest of the rain fell. Also below are more official totals from the National Weather Service, your backyard totals will vary.
Because of this rainfall, flood warnings have been reissued for parts of the southeast with rivers going back above flood stage. In fact, the Big Sioux River may crest near major flood stage between Sioux Falls and Sioux City. Check out the 2 hydrographs below. The first one is for the Big Sioux River at Akron and the second is for the Rock River at Rock Rapids. Both will show you the previous levels of the river, the current level, and then a forecast for the next few days.
I mentioned that more rain is on the way….well unfortunately for some, it doesn’t look like it can be avoided as another storm will roll into the central states and bring wet weather. But this storm will be quite a bit different then the last couple as it will bring much cooler temperatures along with it, giving this storm more of an April feel rather then an early June feel.
First off, check out the anticipated rainfall over the next 3 days across the country courtesy of the Hydrological Prediction Center.
Looks like another half inch to inch and a half could be on the way, especially for areas in the south, but I think it will be the cooler temperatures that everyone will notice the most. Below are two images from one of our computer models showing temperatures on Wednesday at 1pm and then Thursday at 1pm. I circled the 40’s in purple and the 50’s in red.
You can see that basically wherever there is rain falling is where temperatures are in the 40’s, with 50’s found where there is thick cloud cover. So even though high temperatures may actually be in the 50’s and low 60’s, be prepared for a large drop in temperature when the rain moves in.
Prepare yourself for a cool week, but if you check the 7-day forecast, there is light at the end of the tunnel because by the weekend temperatures will be back to normal.
