Today through May 10th: I am watching Thursday afternoon. Perhaps a few strong storms. I am watching Saturday and Sunday. For now, the threat of severe weather appears small. Monitor updates.
.
.
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 advice:
Avoid flooded roadways. There may still be some problem areas from the recent rain event.
.
Weather Discussion
-
- Dry today.
- Scattered showers Thursday.
- Monitoring shower and thunderstorm chances Saturday into Monday.
It will be nice today. Cooler. Quite a bit of sunshine. No weather concerns.
Avoid flooded roadways. Portions of the region have receive 1″ to 7″ of rain over the past 48 hours. Needless to say, this has washed out some roadways and caused travel headaches.
A cold front will move through the region Thursday. This front will spark a band of showers and thunderstorms. See the future-cast radars. The bulk of this will occur Thursday afternoon and then it will end by Thursday night.
An additional 0.00″ to 0.40″ of rain will be possible. Some areas may remain dry through that event.
Some of the thunderstorms could be intense. Monitor.
Friday will be dry. A nice day.
A series of disturbances will push through the region late Friday night into Monday. This will deliver widespread showers and thunderstorms. Locally heavy rain will be possible with this event. Not what farmers want to hear.
If you have outdoor plans Saturday or Sunday, then plan on at least damp conditions and perhaps some downpours. I know it is Mother’s Day weekend.
The front may leave the region by Monday or Tuesday. IF it stalls, then rain chances will continue those days, well. Data is mixed on where the front stalls out. Perhaps the Tennessee Valley.
Usually when a front stalls to our south, it will eventually move back north. Let’s keep an eye on that. That would mean more rain.

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.
- The EC European weather model is in Zulu time.
.
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.
