Re: Severe Weather Threat. April 21st-25th, 2010 High Risk!
I've noticed something the past couple of days. Feel totally stupid for not figuring it out before now.
What I've noticed: last couple of days out west, tornado warnings often indicate a radar indicated twister and spotters confirming it.
I.E. "radar continues to indicate and spotters are tracking a large and dangerous tornado".
But you get over towards the Mississippi River and it's almost always worded "radar indicates a possible tornado."
I'm guessing trees...or the lack thereof...is the reason for that difference.

That is correct - it has to do with trees, hills and HP supercells. Many tornadoes likely will not be initially reported.

It now appears increasingly likely that severe storms will take place over the Ohio Valley today. Low and mid-level winds will increase in response to a deepening surface low which will increase wind shear as well. As a result, this afternoon and evening...conditions will
become favorable for one or more intense lines of storms and rotating supercells especially
over south central Kentucky. The main hazard from these storms will be wind
damage...potentially significant. Tornadoes are also possible, espcially after the first line of storms moves through the area. Some of these tornadoes may be strong and have long tracks. Hail, heavy rain, and cloud-to-ground lightning are likely as well.
Residents need to monitor later forecasts and statements from the National Weather
Service and local media for updates on this developing hazardous weather situation.

If you've ever been to a NASCAR race...or driven by a track while a race weekend is going on...then you know how dangerous this situation is.
They have closed the track and the stands will be empty.
But there are tens of thousands camping around the track in motorhomes, RV trailers, truck campers, and tents. And that many people can't be evacuated quickly. (My wife and I sat in a parking lot at Texas Motor Speedway for four hours one time without the wheels ever moving.)
If a storm were to threaten the track, there would be countless people there that would literally be "sitting ducks".
