Key Points

⛈️ Storms Early This Morning
A line of showers and thunderstorms is moving through the area.  They are producing brief downpours and gusty winds.  The threat of severe weather this morning is low.

🌩️ More Storms Today
Scattered to numerous showers and thunderstorms are expected today, especially across the southern half of the Quad State.

  • Rain chances range from 50% to 80%.
  • A few storms could become strong or severe this afternoon.
  • Damaging winds are the main concern, especially in western Kentucky.  Overall, the risk at one location is small.

Here is the rain probability map for today.  What is the % chance of rain?  Notice that chances are lower in the north and higher in the south.

☀️ Friday Looks Better
Friday is expected to be dry with improving weather conditions.

🌦️ Thunderstorm Chances Return This Weekend
Showers and thunderstorms will return Saturday afternoon/night into Sunday night.  A low chance of showers on Saturday afternoon over mainly southeast Missouri.  Most areas will remain dry.  See the rain probability graphics below.

  • More widespread rain and storms are expected late Sunday into early Monday as a cold front moves through the region.
  • Keep an eye on the forecast if you have outdoor plans this weekend.
  •  A few storms on Sunday could be strong, with gusty winds and hail.  A low-end severe risk.

Weekend

The cold front should move completely out of the area by this evening, ending the threat of thunderstorms. A few leftover showers may continue near the Arkansas and Tennessee border into the evening hours.

High pressure will bring dry, cooler, and more comfortable weather on Friday and likely Saturday as well. There is a small chance of a shower in southeast Missouri on Saturday, but most of the Quad State should remain dry.

By Saturday night, winds will turn back to the south, bringing warmer and more humid air into the region. Humidity levels will rise on Sunday, helping showers and thunderstorms develop during the afternoon.

More widespread showers and thunderstorms are expected Sunday night as another cold front moves through the area. A few storms could become strong or severe, and heavy rainfall will also be possible.

The rain should move out by Monday afternoon or evening. Dry weather is then expected through the middle of next week.

Bottom Line

🌩️ Storms this morning with a lower severe weather risk
⛈️ More storms this afternoon, especially in western Kentucky
☀️ Dry weather Friday
⛈️ More storms Saturday afternoon into Sunday night.  Perhaps linger into Monday.  The peak day of the weekend will be Friday and Saturday.

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

General rainfall total maps for today through Monday.

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.
