We had hail in Indiana yesterday.
I thought PDS was Palin Derangement Syndrome.....
might want to bump the MI ping list on this one.
Radar I’m using.
We’re in a western suburb of Chicago. We had a few very tense minutes where the sky turned black and there were strong gusts. Our TV went out, and we’ve got lots of street flooding. At Mass there were only eight other people. Smallest crowd ever! All schools (and several stores) are closed too. More rain is on the way...
Its already pretty windy here in Southern MI.
My wife is on a plane headed for (I hate to say it) chicago. It has been delayed twice, but is now headed into it.
As my flight instructor said, “Happy Landings!”
There’s a bit of eyebrow-raising and head-scratching from a few people on weather boards at the PDS watch.
Yeah, they had a moderate risk of severe weather yesterday for Oklahoma and that never really materialized. Nothing currently on radar in the area that looks that bad.
