Key Messages

🌡️ Hot and Humid Through Thursday

The hottest weather of the year so far will continue today and Thursday. Afternoon temperatures will climb above 90 degrees, and when combined with high humidity, it will feel like 100 to 105 degrees at times. A little relief is expected on Friday after a cold front moves through.  Stay cool.  Take breaks if you must work outside, as always.

Here are the anticipated heat index values.  Double-click to enlarge this graphic.

⛈️ Storms Return Thursday Night and Friday Morning

A cold front approaching from the northwest will bring another round of showers and thunderstorms Thursday night into Friday morning. Some storms could become strong or severe, with damaging wind gusts and brief heavy rainfall as the main concerns.

The concern for severe weather is slightly greater over the northern portions of southeast Missouri and northern portions of southern Illinois.  Monitor updates.

Here is the current severe weather outlook for Thursday night.  The yellow zone is a level two out of five severe weather risk.  The dark green is the level one out of five threat zone.  The scale ranges from one (low) to five (highest).

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

🌧️ Wet Pattern Returns Late This Weekend

Additional showers and thunderstorms return late in the weekend.

Friday into Saturday afternoon should be a bit less muggy than today and tomorrow.  Shower and thunderstorm chances will wane on Friday morning and Saturday.

The brief break from humidity won’t last long. Muggy conditions will return by Saturday night, along with renewed chances for showers and thunderstorms through Monday or Tuesday.

🌤️ Looking Ahead

The weather pattern next week may support periods of heavy rain, and some areas could experience localized flash flooding. An isolated severe storm cannot be ruled out, but heavy rainfall appears to be the bigger concern at this time.

🌪️ Seven-Day Tornado and Severe Weather Outlook ⛈️

June 10th  through June 16th

A severe thunderstorm is defined as a storm that produces 58 mph wind gusts and quarter-sized hail or larger. 

Current severe weather riskPOSSIBLE.  I am monitoring Thursday night’s thunderstorms.  I am mainly watching the northern portions of southeast Missouri and the northern portions of southern Illinois.  I will keep an eye on trends.   A line of storms will approach from the north northwest and move southeast.  Some of the data rapidly weakens it.  Monitor updates.

I am also monitoring Saturday through Monday.  For now, the risk during this time period appears low, but not zero.

Current tornado riskLOW.  The risk of tornadoes is low through next Tuesday.  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 Thursday night into early next week.  Peak chances will be Thursday night.  Another peak on Saturday night through Sunday night.  I will monitor next Monday and Tuesday.  There will be at least some chance of lightning during that time, as well.

2. Is significant or widespread flash flooding in the forecast? ISOLATED ISSUES.  I will monitor Thursday night’s thunderstorms.  Locally heavy rain could occur where the storms track.  Additional locally heavy rain is possible this weekend into early next week.

Some localized issues are possible.  Areas where thunderstorms repeatedly train over the same area could experience issues.

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

4. Will the temperature rise above 90 degrees?  YES.  A chance of 90 degrees or today and tomorrow.  

5. Is the heat index forecast to rise above 100 degrees? POSSIBLE.  Today and tomorrow. Heat index values will reach the upper nineties and possibly exceed 100 degrees.

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.

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

General rainfall total maps for today through next Wednesday morning.

* As is typical for late spring, totals will vary greatly.  Thunderstorms can double your rainfall totals.  Keep that in mind.

Let’s look at the five-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.
