🔥 Hot and Humid Today — Storm Chances Increasing

Today will be very hot and humid. Southwest winds ahead of an approaching cold front will push temperatures into the 94–101° range. With the humidity, it will feel more like 102–110°. A Heat Advisory is in effect from late this morning through early evening.

⛈️  Storm chances will begin increasing today. Scattered showers and thunderstorms are possible as early as midday, but not everyone will see rain. Storm chances rise significantly tonight, especially across northern portions of the region.

🌧️  Thursday: The cold front will slowly move across the area. Showers and thunderstorms will continue, with the best rain chances shifting into western Kentucky and other southern portions of the region Thursday afternoon and night.

⚠️  A few strong to severe thunderstorms are possible today and Thursday. The main concern will be damaging wind gusts. Today’s Marginal Risk covers most of our region except southern portions of the Pennyrile.  Thursday’s Marginal Risk includes southern Missouri, far western Kentucky, and extreme southern Illinois.  See the graphics below.

🌦️  Friday through the weekend: The front may move back north, keeping our weather unsettled. There will be occasional chances for showers and thunderstorms Friday and Saturday, with a smaller chance Sunday.

☀️  Sunday night and Monday currently look dry. Another cold front could bring additional shower and thunderstorm chances Tuesday into the middle of next week.

🌡️  Temperatures: Friday should briefly turn closer to normal. The heat returns over the weekend, with highs mostly in the lower 90s, followed by lower to middle 90s Monday.

Bottom line: 🔥 Dangerous heat today → ⛈️ increasing storm chances tonight → 🌧️ storms continue Thursday → 🌦️ unsettled at times Friday and Saturday → ☀️ drier Sunday night and Monday.

🌧️ Best rain chances Wednesday night and Thursday.

🌡️ Less hot and more seasonable late in the week and early next week.

In the long range, the ensembles are showing some cooling.  Let’s hope this verifies.

Let’s Look At The Rainfall Totals Forecast

⚠️ Summer thunderstorms can produce a wide range of totals.

Let’s look at the 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.
