INFO ON HURRICANE DEAN

Over 10 inches of rain has fallen in parts of Oklahoma, Minnesota and Wisconsin in the last 24 hours. Below is the map from the NWS Gauge-Adjusted Doppler-Precip Site showing the amounts in Oklahoma:

The Oklahoma event is actually the remnants of Tropical Storm Erin and it's funny, if you look at the radar animation from the last 4 days (see link below), it looks like it lost its circulation as it moved northwest across West Texas, but then regained it this morning over Oklahoma, in fact it has a rain-free "eye" feature this morning.

Probably what we are really seeing is an MCV as the result of the overnight MCS [JessePedia] which developed with the remnants. You can see a satellite shot of the MCS last night below (note the purple dot is not an "eye" feature but rather a taller/colder "overshooting top" [WikiPedia].

At this location, you can download the satellite loop showing the MCS as above, a water vapor satellite loop, a regional 4-day radar animation, a local radar animation from this morning in Oklahoma City showing the "eye." USAToday has an article detailing the flooding and power outages in the state.

Here's what Wisconsin and Minnesota got last night:

Incredibly, Forbes reports that five people were killed in Minnesota by the flooding, and they quote 12 inches as the highest amount. This flooding was caused by a slow moving, intense line of thunderstorms last night.
