One thing I've seen people misunderstand: this isn't just a problem for the areas missing balloon launches. Those observations help initialize the forecast models, and any missing data can degrade forecasts far downstream as the model evolves. If you're in Ohio, you should care just as much about a missed launch in Montana as someone who lives there.

WPC has a Moderate flood risk on the map today, their second-highest, for parts of Missouri, Oklahoma, and Kansas.
The core sits near the Springfield area down toward Rogers and over by Stillwater. Storms keep parking over the same towns, and after this week the ground just can't soak up any more, so it runs straight to the roads.
If you're in there today, give yourself extra time and never drive into water across a road. You can't tell how deep it is.

Tornado threat has been UPGRADED for tomorrow across Illinois, Indiana, Kentucky, and Missouri!
A few tornadoes are possible tomorrow afternoon and evening. Live stream is possible!
Hen-egg-size hail, 2 inches and up, is the early threat with the storms going up across the southern Plains today.
The best shot at it is around Anthony, Dodge City, and Kingman, Kansas. That's stones big enough to crack a windshield, so anything parked outside out there is worth tucking away. The strongest lone storms drop the worst of it before they clump together this evening.

A Level 3 of 5 severe risk is up again today across Wyoming, Colorado, and Nebraska.
The big story is hail. Storms fire off the high ground this afternoon from southeast Wyoming into northeast Colorado, and the strong winds up high are lined up to build true supercells. We're talking stones 3 to 4 inches across, baseball size and bigger. A quick tornado or two is on the table, and once these clump into a line later they can throw down damaging gusts.
If your car's out in the open out there, get it covered before this afternoon.
A Level 2 of 5 severe risk covers two very different setups today.
Out on the High Plains in northeast Colorado, storms fire off the high ground this afternoon on their own, and that's where the very large hail comes. A tornado or two is possible there too.
The bigger area runs across Virginia and North Carolina. Storms roll off the mountains this afternoon and push toward the coast, with damaging wind the main worry. Beyond that, near the warm front up around DC and Baltimore we flagged yesterday, a couple of quick tornadoes are still possible.
