Click here for the latest forecast. 

Preliminary Friday Forecast looks to be a major severe weather risk 
day from the Ozarks then east up the Ohio Valley. 
The yellow, hatched area has an enhanced risk of tornado with some likely strong. The brown area has a significant risk of tornadoes. 

Here is an expanded look at the entire significant tornado risk area. 

Damaging Wind Risk
Here are the risk categories:
  • Purple hatched, including St. Louis, Cape Girardeau, and Terre Haute, has a high risk of thunderstorm wind gusts of 75 mph or stronger. 
  • Red hatched, an enhanced risk of wind gusts of 75 mph or stronger. 
  • Yellow, a significant risk of wind gusts of 60 mph or stronger.
It is possible that a derecho will form in Missouri or near the Mississippi River and move east. 

If you live in a mobile home or need a public shelter, you will find lists and maps here. 

With this combination of tornado and derecho risk, I strongly urge the following safety measures:
  • Power outages are likely. In situations like these, because of the large geographic area that may be  affected, some may be without power for days.
  • Make sure your car is fully fueled Friday morning. 
  • It is a good idea to have some extra cash.
  • Your smartphone and laptops should be fully charged but disconnect them when you hear thunder to prevent damage from a power surge. 
  • If you have a chainsaw, make sure it is powered. 
  • Be sure you monitor the weather tomorrow afternoon and night and have multiple ways of receiving warnings. If you have a weather radio, install fresh batteries.

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...
