Mississippi Valley Severe Storm Update

By -
Here is my forecast for now through midnight.
Readers in east central and southeast Iowa should really keep an eye on the weather the next few hours. Giant hail (≥4") likely if supercell thunderstorms develop. So, I would urge you to put your car in the garage along with anything else that can be damaged by hail. I also believe it is quite possible for a tornado or two if supercell thunderstorms develop.

If you have friends/relatives in the purple area, please make sure they are aware of the threat.

Here is the radar at 3:37pm.

Note: this forecast has been updated. Go here for the latest.  Update at 6:45pm. The National Hurricane Center now seems to agree with my forecast.  The red area is where they are forecasting an 80% chance of a tropical depression, or stronger storm, to develop sometime during the next seven days. I believe the best chance is in the Tuesday to Thursday period for tropical storm development.  Update at 6pm: The afternoon model runs, among the models I trust, continue to show a good chance (at least 50%) of a tropical storm forming in the western Gulf. I will update this forecast Sunday morning.  Update at 1pm: The new run of the models I trust are in and my confidence has only grown that there is a threat of a tropical storm developing in the western Gulf of Mexico to the west of the orange line. The rest of this forecast (below) is still valid.  People in the USA and northeast Mexico (west of the orange line) should keep an eye on the weather this week. While t...
