Today through September 30th: At this time severe weather is not anticipated.
Today’s outlook (below).
Light green is where thunderstorms may occur but should be below severe levels.
Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.
One is the lowest risk. Five is the highest risk.
A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
The tan states are simply a region that SPC outlined on this particular map. Just ignore that.
The black outline is our local area.

Weather Discussion
-
- Lingering clouds.
- Warmer today into Sunday.
- Rain chances late Sunday into Monday.
- Much coole next week!
I keep saying I am going to take a few days off! Eventually, that will happen.
There was only two changes to yesterday’s forecast.
Clouds will linger today, especially over Kentucky/Tennessee. Clouds will clear west to east through the day into tonight.
Where clouds linger, temperatures will be a few degrees cooler. That is the nature of the beast.
Dry today through Sunday morning.
A strong cold front will sweep across the region Sunday night/Monday.
This will bring showers and thunderstorms to the area.
If you read yesterday’s update, then you would know that trends were towards a wetter Sunday night/Monday.
I have increased rain chances during both time periods.
At this time, severe weather does not appear to be a concern. Remember, autumn often does bring severe weather. This is usually from mid-October to November. Tornadoes are common during this time period. Thus, let’s pay attention over the coming two months.
We will then settle into winter! Hard to believe.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.
What should I take from these?
- The general idea and not specifics. Models usually do well with the generalities.
- The time-stamp is located in the upper left corner.
.
What am I looking at?
You are looking at different models. Meteorologists use many different models to forecast the weather. All models are wrong. Some are more wrong than others. Meteorologists have to make a forecast based on the guidance/models.
I show you these so you can see what the different models are showing as far as precipitation. If most of the models agree, then the confidence in the final weather forecast increases.
