What you need to know.

Key Points

  2.   Some of the thunderstorms could produce 60 mph wind, nickel size hail, torrential downpours, and frequent lightning.
  3.   A few severe thunderstorm warnings will be possible today and tonight.
  4.   The tornado risk is low, but not zero.   Monitor your Beau Dodson Weather app.  I will push out information if necessary.
  5.   Have your Beau Dodson Weather app on.  Check it.  Make sure you have not logged out of the app.

Storms continue to develop from NW to SE.  The main concern is south of the white line.

Heavy rain is the first concern.  Isolated high winds and then lightning, of course.

 

5:30 PM

Flash flood update

..

5:18 PM

Severe thunderstorms are forming in Missouri.  I continue to monitor their track.

They are moving southeast at 25 mph.

.

5:15 PM

A severe thunderstorm watch may be issued shortly for this area.

There is a 40% chance of a severe thunderstorm watch.

 

4:45 PM

Storms are beginning to redevelop in Missouri.  Let’s watch them as they track SE into our area.

Some storms could be severe.

 

4:30 PM

I am watching the radars to see where storms re-fire over the coming hours.

Some storms could be severe.

And the NAM model shows similar

.

2:55 PM

Butler County

A quick update on the Butler County storms.

Storms continue, mainly in the /southsouthwest portion of the county. This storm likely has downburst winds over 60 mph. Wind damage is likely.

There is also some rotation with the storm. Be weather aware as this storm pushes southeast at 25 mph. Seek shelter if necessary.

.
1:25 PM

Stoddard, New Madrid, Pemiscot, and Dunklin Counties.
Lake County, Tennessee.

I will monitor other counties to the east.

Thunderstorms are moving through the Missouri Bootheel.

The line is moving south/southeast. From time to time, these storms pulse up enough to produce nickel size hail and perhaps isolated wind damage. For now, that is the exception.

The storms may hold together all the way through the Bootheel. If so, there will occasionally be high winds with them. Lightning and heavy rain, of course.

.

1 PM

Storms moving into Butler County could become severe with quarter size hail and high winds.

Round one of storms is mainly going to impact southeast MO. You can see it here. Additional storms will form later today and tonight.
For now, I am simply watching the MO storms.
.

8:45 AM update/discussion

I posted future-cast radars below, as well.  Those give you an idea of what the models are expecting.  It won’t be exact, but it will at least give you an idea of how the models see the different rounds of thunderstorms developing.

One round of thunderstorms is already pushing into southeast Missouri and southern Illinois.

As of this writing, at 8:45 AM, a heavy thunderstorm was moving into Jefferson County, Illinois.  It was producing gusty wind, heavy rain, and lightning.

It is moving southeast.

Other storms are lined up across northeast and east-central Missouri.  These storms will push southward with time.

Static radar image from 8:45 AM.

See the live radars for the latest imagery.

.

The WPC has issued a flash flood statement.  The pink zig-zag zone is where they are concerned about heavy rain over the next few hours.  This is round one of this storm system.

Double click on this image to enlarge it.

.

The atmosphere is fairly unstable with weak wind shear.  There are some ingredients for isolated wind damage today.  If a thunderstorm were to tap into a boundary then some rotation could also occur.  Boundaries are left over from previous thunderstorms.

Storms will mostly be moving south and southeast.

The Storm Prediction Center has outlined our region for a level one out of five risk of severe weather.  One if the lowest risk.

Basically, it means what I said above.   A few storms could produce damaging wind gusts.

There will likely end up being two distinct rounds of thunderstorms.  This first round that is on radar now and then new development this evening into tonight.

Tonight’s round may produce some flash flooding.  Storms may train over the same areas.  If this happens then torrential rain totals can occur in a short period of time.  One to three inches in thirty-minutes.  This can lead to roads flooding.

The Hrrr model likes southwest Illinois, southeast Missouri and far western Kentucky for the heaviest rain totals.

If flash flooding develops, then avoid flooded roadways.

Storms will end Sunday morning and afternoon.  That will occur as the cold front pushes away from the region.

Monitor your Beau Dodson Weather Talk app today.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.

What should I take from these?

  1. The general idea and not specifics. Models usually do well with the generalities.
  2. The time-stamp is located in the upper left corner.
  3. The EC European weather model is in Zulu time.

.

What am I looking at?
You are looking at different models. Meteorologists use many different models to forecast the weather. All models are wrong. Some are more wrong than others. Meteorologists have to make a forecast based on the guidance/models.

I show you these so you can see what the different models are showing as far as precipitation. If most of the models agree, then the confidence in the final weather forecast increases.

You can see my final forecast at the top of the page.

Today’s severe weather outlook from the Storm Prediction Center (below).

Light green is where thunderstorms may occur but should be below severe levels.

Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.

One is the lowest risk. Five is the highest risk.

A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.

The tan states are simply a region that SPC outlined on this particular map. Just ignore that.

The black outline is our local area.
