Have you ever see a green sky like that. Best I can see, the time on the clock is 3:35 pm and it looks more like nighttime. The green sky was likely due to the light hitting the monster sized hail up in the cloud. (pic. from Jaden Miller)
One hailstone measured 4.3″ in diameter. There were several reports of hail 4″ in diameter. It takes a heck of an updraft to keep a hailstone like that in the air.
There were 24 reports of measured wind gust of hurricane force (over 74 mph). Howard SD had a peak gust of 99 mph. The Huron SD airport measured 96 mph. Agar SD had 91 mph with Wall Lake at 85 mph. The Sioux Falls Airport had a gust to 80 mph.
Nationwide, there were 280 reports of wind damage, along with 37 reports of large hail (7 of those reports were of hail 2″ or more in diameter. Severe weather occurred in 17 different states.
As of 2:30 am Wed., there were 19,262 customers without power in OH, 19,015 in California (this state always seems to have a lot of outages), 17,451 in Indiana, 10,129 in North Carolina and 6,479 in South Dakota.
They’ve done an excellent job of getting power restored in SD. At one point, 20,000 customers were without power in the Sioux Falls area alone and several counties had over 50% of the counties without power. There were many trees and wires down and some building damage, including one home that lost a roof.
There were also some extremely heavy rainfall totals. This is a rain gauge showing 5″ of rain near Huron SD.

Flood Watches and Warnings remain in effect for much of northern Indiana, northwest Ohio and five Michigan counties that border Indiana and Ohio. Check out these 48-hour rainfall totals – up to 9″ near Fort Wayne.
Today (Wed.) there are three large areas under a Slight Risk (level 2) for severe weather. The first area is from Central and Southern Indiana to the Atlantic Ocean. The second covers much of the state of Montana. The thrid area is NE Colorado, SW Nebraska and NW Kansas.
The risk for tornadoes is small. This is mainly for hail and especially for strong winds. While a general (not severe) storm is possible south of Kent County, it’s likely any significant rain/storms will be across the border in Indiana and Ohio.
One more note from SPC concerning severe weather early next week: “Severe potential should persist into the early/middle portions of next week as the upper trough continues southeastward across the Midwest, Great Lakes, OH Valley, and eventually the eastern states. However, there is currently too much uncertainty in the placement and evolution of the upper trough and related surface features to include any 15% severe areas from Day 6/Monday onward.”
