June 9, 2026: Additional shower and thunderstorm chances. Warm/hot and humid.

.

I am going to try to streamline the blog.  Centered on the most important aspects of the forecast.   

.

Key Messages

🥵 The hottest stretch of the year so far begins today.

  • Afternoon temperatures will climb close to 90 degrees.  Temperatures will be a bit cooler where clouds and storms linger.
  • High humidity (dew points) will make it feel even hotter, with heat index values reaching around 105 degrees at times through Thursday.
  • Some relief from the heat and humidity is expected by Friday and Saturday.

⛈️ A few storms could become strong and/or severe today into this evening.  See the graphics below.

  • The hot, humid air will help fuel thunderstorms.  Locally heavy rain is likely in areas that do receive storms.
  • A few storms may produce damaging wind gusts up to 60 mph.

⛈️ More showers and thunderstorms are expected Thursday afternoon into Friday.

⛈️ Scattered showers and thunderstorms from Saturday to Monday (around 30% to 40% chances from Saturday to Monday)

  • Some storms could be strong and/or severe on Thursday afternoon and Thursday night.
  • The main threats will be damaging winds and brief periods of heavy rain.

Bottom Line

  • Today through Thursday: Hot and humid with heat index values near 105°.  A bit lower where clouds are thicker.
  • Tuesday afternoon/evening: A few strong storms possible.
  • Thursday night into Friday: Another round of showers and thunderstorms, some potentially strong. 🌡️⛈️💨🌧️

A few informational graphics from the NWS.

There is a marginal risk (dark green zone) that a few thunderstorms could be severe today into this evening.  The light green zone is where storms are possible, but likely below severe limits.

The Storm Prediction Center could still shift this around a bit.  Monitor your Beau Dodson Weather App.

.

Isolated flooding is possible in the heavier storms.  Flooding should not be widespread.

.

A heat advisory covers portions of the area.  That means heat index values could reach above 100 degrees.

Muggy air.  Tropical air.

.

Another chance of severe weather on Thursday afternoon and night.  I will need to monitor the timing of this.

The yellow zone is a level two out of five risk.  The dark green zone is a level one out of five risk.  One is the lowest.  Five is the highest.

The light green indicates where storms are possible but are likely to remain below severe limits.

This graphic could definitely change between now and Thursday afternoon.  Continue to monitor updated forecasts.

Storms will approach from the northwest and move southeast.

🌪️ Seven-Day Tornado and Severe Weather Outlook ⛈️

June 9th  through June 15th

Current severe weather riskPOSSIBLE.  A few of the thunderstorms this afternoon and evening could produce strong wind gusts and small hail.  There is a risk that a few of the thunderstorms will produce damaging wind gusts.  I am monitoring Thursday night.  Additional storms are likely.  See the graphics above for more details.

Current tornado riskLOW.  The risk of tornadoes is low through Sunday.  I will keep an eye on the Thursday night thunderstorms.

Current confidence level in the tornado forecast: Medium.

Seven-Day Hazardous Weather Outlook

1. Is lightning in the forecast?  YES.   A chance of lightning today through Tuesday night.

Chances of lightning Wednesday through Thursday morning are low.  Another chance on Thursday afternoon into Friday.

Chances of lightning on Saturday and Sunday appear low for now.  I will monitor it.

2. Is significant or widespread flash flooding in the forecast? SCATTERED ISSUES.  A few of the thunderstorms over the coming days will produce heavy rain.  If thunderstorms train over the same location, then pockets of flash flooding could develop.  As always, avoid roadways that have significant flooding.

There was flooding in some counties yesterday.  Cape Girardeau County received over 3.5″ of rain in less than one hour.  This caused numerous roads to flood.

The moisture content of the atmosphere is extremely high (near record levels).  That means that slow-moving thunderstorms can produce one to two inches per thirty minutes.  These types of rainfall rates can cause problems.  Avoid flooded roadways.

3. Will non-thunderstorm winds top 40 mph? NO.    

4. Will the temperature rise above 90 degrees?  YES.  A chance of 90 degrees or above today, tomorrow, and Thursday.  I will monitor Friday and Saturday (upper 80s are likely).

5. Is the heat index forecast to rise above 100 degrees? POSSIBLE.  Today, tomorrow, and Thursday. Heat index values will reach the upper nineties and possibly exceed 100 degrees.  This will depend on cloud cover and thunderstorms.  Clouds would keep temperatures a bit lower.

6. Is the heat index forecast to rise above 110 degrees? NO.

Your body responds to the heat index.  The heat index is more important than the actual temperature.  More information about the heat index: Click here.

Dew Points.  A muggy few days ahead of us.

Notice how humid it feels outside today?  That is because we have high dew points.  Dew point measures the moisture in the air.  It is a better gauge of “mugginess” than humidity.

Look at today’s dew points.  Muggy!

Dew points in the mid to upper 70s.  That is air you wear.  Uncomfortable.


By Friday and Saturday, the dew point temperatures will be a bit lower.  It will feel a bit better outside than the coming days.

Let’s Look At The Seven-Day Rainfall Totals Forecast

General rainfall total maps for today through next Tuesday morning.

* As is typical for late spring, totals will vary greatly.  Thunderstorms can double your rainfall totals.  Keep that in mind.  I would not be surprised if a few spots receive more than three inches of rain this week.  Perhaps in a short amount of time.

Let’s look at the four-day rain probability maps.   What is the % chance of rain?

These maps are broken down into 12-hour time periods.

* Remember, a 20% chance of rain during the summer months does not mean that it will not rain.  It means there will be a few thunderstorms on the radar.

** NEW SERVICE **  I have partnered with WeatherCall to bring you an added layer of protection.
.
More information on the WeatherCall subscription service at the link below or use the QR code.

.
We have a new service to complement your www.weathertalk.com subscription.  This does NOT replace www.weathertalk.com It is simply another tool for you to receive severe weather information.

I use it myself. I encourage everyone to have 3 to 5 ways to receive severe weather information. All sources can fail, and the more sources you have, the better prepared you will be in the event of severe weather warnings.
.
WeatherCall will call your cell phone or home number if your home is under a tornado or severe thunderstorm warning.  It only calls you if your home is inside the warning box/polygon. If you are outside the warning box/polygon, it will not disturb you.
Here is a video with more information and a demonstration of how it works.
