June 12, 2026: Monitoring additional shower and thunderstorm chances this weekend.

.

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

.

Key Messages

  • Friday will bring a short break from the heat and humidity. However, muggy conditions will return Saturday afternoon and may last into Sunday.  Any remaining morning showers and thunderstorms will push southward and out of the area.
  • Another round of showers and thunderstorms is expected Saturday through Saturday night, with some rain possibly continuing into Sunday morning. A few storms could become severe, and heavy rainfall may lead to localized flash flooding.
  • 🌤️ Early next week looks cooler and less humid. There is a 70% to 90% chance that humidity levels will stay comfortably low on Monday and Tuesday.
  • The cooler, drier weather won’t last long. Warmer temperatures, higher humidity, and additional chances for rain and thunderstorms are expected to return by Wednesday through Friday.

Daily summary

🚗 Saturday is a travel day for me.  So, no update during the day.  If severe weather develops, then I will try and send those warnings to the app. 🚗

Today:

Showers and thunderstorms will continue to push across the region.  Some of these storms will produce locally heavy rain and gusty winds.  Lightning, as well.

See the live local radars below.

By this afternoon, the bulk of this activity will push out of the area.  Moving into Arkansas and Tennessee.

That will leave us with dry weather this afternoon and tonight.

Saturday:

Several rounds of showers and thunderstorms are likely.  Perhaps one round in the morning.  Another round into the afternoon.

The morning round has less confidence.  Data is mixed on this idea.  Monitor.

Showers and thunderstorms will continue into Saturday night and Sunday.

If you have outdoor plans on Saturday and Sunday, then monitor updates.  A few warnings are possible.

.

Sunday:

Showers and thunderstorm chances will continue.  The good news is that they should be moving off to the east as the morning wears on.

Sunday afternoon may be dry over a chunk of the region. Especially, Missouri and Illinois.  It will be close in timing.  I will monitor it.

.

Monday and Tuesday:

Monday and Tuesday have trended drier.  Not as hot.  Less humid.  A couple of nice days.

.

Wednesday and Thursday:

A warming trend. Increasingly humid, as well.  I will need to monitor showers and thunderstorms as we move deeper into the week and next weekend.  With higher dew points (moisture), at least scattered thunderstorms will be a concern.  At this time, severe weather is not anticipated.  As always, thunderstorms in June can produce heavy rain, lightning, and gusty winds.

.

Next weekend: Right now, it appears it will be warm with scattered thunderstorms.

🌪️ Seven-Day Tornado and Severe Weather Outlook ⛈️

June 12th  through June 18th

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

Current severe weather riskLOW RISK, OVERALL.  A few storms this morning could produce strong wind gusts.

I am monitoring Saturday and Saturday night.  Some of the thunderstorms could produce strong and gusty winds, heavy rain, and frequent lightning.  I can’t rule out a few severe thunderstorm warnings.

Here is my thunderstorm concern meter.


.

🌪️ Current tornado riskNOT ANTICIPATED.  Tornadoes are not anticipated at this time.

Current confidence level in the tornado forecast: Medium.

.

Seven-Day Hazardous Weather Outlook

1. Is lightning in the forecast?  YES.  A chance of lightning this morning. The rest of Friday and Friday night will be lightning-free (low chance). Another peak on Saturday afternoon through Sunday night.  Scattered lightning on Monday.

2. Is significant or widespread flash flooding in the forecast? ISOLATED ISSUES.  Widespread issues are currently not anticipated.

Locally heavy rain arrives on Saturday and Sunday.  Thunderstorms, where they occur, will be locally heavy.

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?  MONITOR.   Next Thursday and Friday.

5. Is the heat index forecast to rise above 100 degrees? UNLIKELY.

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.

This is a broad-brush overview of the entire region.

* Scroll down to see your local city rain probability maps.

Today’s chances will be during the morning and mainly across my southern counties.  Boothell into west Kentucky and Tennessee.

Ending this morning north to south.

There are some questions about Saturday’s rain chances.  Whether we see a morning round is still a question.  Increasing chances on Saturday afternoon, evening, and night.  Peak chances will likely be Saturday evening and night.  Monitor.

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

General rainfall total maps for today through next Thursday morning.

* The WPC went pretty high on these numbers.  I will monitor trends.

* 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 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.
