July 3, 2026: Hot and humid. Scattered thunderstorms.

.

.

Key Seven-Day Weather Information

🥵 Hot again today.  Rain chances increase this weekend.

Another day of heat and high dew points.  Afternoon temperatures combined with high dew points will make it feel like 105 to 112 degrees. An Extreme Heat Warning remains in effect through this evening.

For the July 4th holiday, increasing clouds and scattered showers and thunderstorms will provide a little relief. Heat index values should be a bit lower, ranging from 102 to 107 degrees on Friday and 98 to 105 degrees on Sunday.

The humidity will stick around into next week, but slightly cooler temperatures should keep heat index values mostly in the 90s instead of the dangerous levels we’ve seen this week.

⛈️ Storm Chances

As always, during the summer months, thunderstorms can produce pockets of heavy rain, wind damage, and lightning.  All of that heat energy has to go somewhere.  Stay weather aware.  If storm clouds threaten, then move indoors until the storms pass.

I would not cancel any holiday plans.  Just be aware that a few storms are possible.

⚠️ A few scattered showers and thunderstorms will develop this afternoon and evening, mainly across the eastern half of the region. Some of these storms could become strong, and the eastern counties are under a Marginal Risk for severe weather.

Here is that marginal risk.  The dark green is the level one risk.  The levels range from one to five.  The light green is where storms are possible, but likely not severe.

As always, don’t get caught in the exact location of the colors.  The SPC could move this around a little bit today.  Just know that a few storms could be intense later today.

Rain chances will continue through the holiday weekend and into early next week as several weather systems move through the area.

  • Saturday: A 30% to 40% chance of showers and thunderstorms.
  • Sunday through Tuesday: A 40% to 60% chance.
  • The best chance for rain will be across western Kentucky on Monday and Tuesday, especially near a slow-moving cold front.

Wednesday through Friday of next week:

The slow-moving front is expected to remain near the region through the middle and latter part of next week, keeping daily chances (20% to 40%) for scattered showers and thunderstorms in the forecast.

🌪️ Seven-Day Tornado and Severe Weather Outlook ⛈️

July 3rd through July 9th

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

⛈️ Current severe weather riskSCATTERED.  Summer storms can produce frequent lightning and isolated downburst winds.  Heavy downpours, as well.  Winds can be strong enough to bring down tree limbs and power lines.

🌪️ Current tornado riskNONE.   

🌪️ Current confidence level in the tornado forecast: HIGH.

Here is my weekly thunderstorm concern meter.

Seven-Day Hazardous Weather Outlook

1. Is lightning in the forecast?  SCATTERED.  Lightning is possible this afternoon into next week.  Campers or those with outdoor events should monitor live weather radar and lightning data.  Links at the bottom of the page.

2. Is significant or widespread flash flooding in the forecast? ISOLATED ISSUES.  Keep in mind that slow-moving summer storms can produce torrential downpours.

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

4. Will the temperature rise above 90 degrees?  YES.  Today through Sunday.

5. Is the heat index forecast to rise above 100 degrees? YES.  Today through Sunday.

6. Is the heat index forecast to rise above 110 degrees? POSSIBLE.  Today and perhaps tomorrow.

Here are the heat index values

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

There will be scattered torrential downpours in summer storms.  Same as every summer.  That will not be captured by these graphics.

⚠️ This won’t be exact because the graphic is trying to predict where scattered summer storms will form.

Take a general idea from these graphics.  Many areas will receive little rainfall.  Some will receive quite a bit in slow-moving summer storms.

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.

* Future-cast radars are rarely exactly right.  Take the general idea from this animation.  These models do their best to forecast where precipitation will develop and move.  In the end, they are a model.

Green is rain.  Yellow is moderate rain. Orange and red indicate locally heavy rain.

** 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.
