Very impressive wind event underway. ASOS report for O'Neill of a 76 MPH gust, with mesonet from the area topping out at 88 mph. Link to comment Share on other sites More sharing options...
Chinook Posted May 12, 2022 Share Posted May 12, 2022 New tornado watch in northeast South Dakota, that shows 70% probabilities of 10 or more wind reports, also the same with hail, and moderately high probabilities of tornadoes, EF2-EF3 tornadoes, as it makes sense with the outlook for today.

Chinook Posted May 12, 2022 Share Posted May 12, 2022 Now, KFSD radar showing 80-100 knots base velocity of the rain within the line of storms at the state border. I think a few areas get 80-100mph wind gusts Yes, I know knots are not miles per hour, but hey, this actually kind of makes sense as the measured surface winds are a little below the measured base velocities.

Chinook Posted May 13, 2022 Share Posted May 13, 2022 We've got a derecho, most likely, considering the strict official definition of the word derecho. There are a huge amount of storm reports in the same area. Some of these are from the morning in Minnesota. 2 Link to comment Share on other sites More sharing options...
Chinook Posted May 13, 2022 Share Posted May 13, 2022 this group of storms has gone from central Nebraska and now is seen on Duluth's radar, continuing with wind reports at some 68 kt winds shown in the clouds on base velocity, where the radar sees the wind the best.

Chinook Posted May 13, 2022 Share Posted May 13, 2022 In South Dakota today, this incoming squall looks like a wall of dirt (I think it's mostly clouds and rain, maybe dirt) and then the video looks black after this. I'm sure it wasn't as black as night in reality. Link to comment Share on other sites More sharing options...
