Today through October 10th: Organized/widespread severe weather is not anticipated. Monitor updates. We typically see an increase in severe weather activity during the autumn months.
.
.
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
-
- Drought.
- Dry weather to continue.
- Field and brush fire concerns continue to increase
- Monitoring frost chances Friday and Saturday night.
.
Weather advice:
Avoid burning brush and leaves. Fire conditions are becoming an issue in many areas.
.
Current Weather Discussion
Well, what is there left to say. It is dry. There is no rain in the current forecast.
There have been numerous fires over the last two weeks. Use care if you must burn brush or fields.
Most of the region is experiencing an unusual dry spell. The last significant rain at The Weather Observatory was a month ago. This is unusual, to say the least.
There were some storms a week ago across the Missouri Bootheel and southern Missouri.
Let’s take a look at a few maps.
30 day precipitation anomaly. Many areas are dry to very dry.
Double click images to enlarge them.
Here is the 30 day percent of normal rainfall numbers.
Precipitation totals over the last 14 days.
Precipitation totals from the last thirty days. Double click the image for a better view. Hard to see the boundaries.
I do not see any rain through at least next Monday. This pattern has locked itself in tight.
A dry cold front will pass through the region Thursday. It will be mild ahead of the front and chilly behind it.
I can’t rule out patchy frost Friday and Saturday night. The chances will be higher across southeast Missouri and southern Illinois vs western Kentucky, the Missouri Bootheel and northwest Tennessee.
With that said, if winds subside both nights then frost could form just about anywhere in the region. Let’s monitor trends.
Either way, frost or no frost, it will be chilly this coming weekend.
Highs Friday and Saturday will likely remain in the sixties. Autumn air.
You can see that surge in cooler temperatures in this temperature anomaly animation. Red is above average temps and blue would be below average temps.
Long range.
The GFS model is showing a chance of rain around October 13th and October 16th/17th.
This is what we call lala land in the model world. It is so far out that confidence is zero. With that said, at least we have something to watch over the coming days.
October 16th and 17th

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.

The Winter Outlook has been posted. Another La Nina winter. As always, there will be wild cards in the forecast.
La Nina means that portions of the Pacific Ocean are cooler than normal. El Nino means that the Pacific waters are warmer than normal.
Learn more about La Nina at the following link CLICK HERE
La Niña means Little Girl in Spanish. La Niña is also sometimes called El Viejo, anti-El Niño, or simply “a cold event.” La Niña has the opposite effect of El Niño. During La Niña events, trade winds are even stronger than usual, pushing more warm water toward Asia. Off the west coast of the Americas, upwelling increases, bringing cold, nutrient-rich water to the surface.
These cold waters in the Pacific push the jet stream northward. This tends to lead to drought in the southern U.S. and heavy rains and flooding in the Pacific Northwest and Canada. During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North
.
No two winters are alike. No two La Nina’s are alike.
The last two winters have been La Nina winters. Both winters delivered a variety of weather conditions.
As you know, during the past two winters we did experience severe thunderstorms and tornadoes. That is not unusual for La Nina conditions.
I do expect an increased risk of severe thunderstorms and ice. Those are common during the La Nina winter years.
We will have to monitor the NAO. If it does go negative then we have increased probabilities of cold air intrusions.

Let’s keep in mind, that long range forecasts are less accurate than short-range forecasts.
What we can’t tell you are the possible extreme events. You could have a mild December and January and the winter be backloaded with cold and snow during the Month of February. Or, the other way around.
We can’t tell you if there will be one large ice-storm or one large tornado outbreak. Long-range outlooks don’t work that way.
People tend to remember winters as severe if there is a mega-event. Like the big ice storm in 2009. Everyone will remember that winter. Like the December tornado last year. Everyone will remember that winter.
We are able to tell you, with some degree of certainty, the overall generalities of the winter.
Of course, I understand that everyone wants to know if there will be a big snowstorm or a big event. We aren’t that accurate, yet. Those type of forecasts are left for short-range weather outlooks. Not long range ones.
Here is what will influence the winter.
ENSO. La Nina. The third year in a row. Rare to have three La Nina’s in a row. This has only happened three times in recorded history.

The graphic below shows the top analogs. Let me pull this graphic out from the above one.
Analogs are years that are similar to the current one. We use analogs to determine how this year might act compared to recent years with similar conditions.
Typically, in our region, snowfall totals are lower during La Nina winters.
The bottom three USA graphics indicate that possibility. Last year delivered below average snowfall totals (for most of our area).

The graphic below shows you the temperature outlooks from a variety of super models.
The first four USA graphics are temperature outlooks. All four are warmer than average for our local area. Orange and yellow.
The second four USA graphics are precipitation outlooks. Typical for a La Nina winter, we are seeing the risk of average to above average precipitation in the Ohio Valley.
Only one model shows below average precipitation. On the precipitation graphics (the bottom four USA images) green is above. Yellow is below.

Outlook thoughts.
Odds favor December through February, when all is said and done, averaging above normal in the temperature department. Above average in the precipitation department.
That certainly does not mean there won’t be cold spells.
Our region typically experiences a wide variety of weather during the winter months. That includes snow, ice, and severe thunderstorms. I would be surprised if this winter doesn’t deliver those conditions.
