Looks like windy.com is showing short-term trends, perhaps driven by things like “how long since it last rained”, etc. Michigan is showing severe drought, and then you set the date to the 12th and it all clears to normal (there’s rain in the forecast around then.)
It’s a lot different than the long term trends driven by total annual precipitation, snowpack, etc.
I’ve found it to be pretty accurate to not drive into potential tornadoes as it uses pretty up to date data which lets me track storm paths.
The difference between “that looks really bad” and “ that looks really bad but will be moved on by the time I get there” is very helpful. Plus being able to text a screenshot of me about to drive into a major storm cell to the owner of my truck is priceless.
Nice, my neck of the woods is absolutely parched :D. Some rain predicted this week though. I heard France was really bad but it doesn't look too bad in comparison.
