Today through September 18th: Organized/widespread 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.

-
- Calm weather.
- Warming trend late week.
- We need more at home severe weather spotters. Please consider attending one of the free online spotter classes. See details below.
- Winter Outlook. I posted the winter outlook towards the bottom of the page.
.
Weather advice:
Locally heavy downpours this weekend. Avoid flooded roadways. Isolated brief water issues are possible where slow moving storms occur.
Lightning will also be a possibility.

Current Weather Discussion
We are waking up to a cool and foggy morning. Fog for some, at least.
There were some lows in the 40s! You can see this on the 7 AM temperature map.
The Weather Observatory recorded a low 0f 51.9 degrees with some dense fog.
There will likely be a few clouds today. Especially as you drive north northeast towards southeast Illinois and northwest Kentucky.
Elsewhere, there should be quite a bit of sunshine.
You can see the large upper level low over the Ohio Valley on this map. It is centered over northern Illinois and Indiana. There were even some showers this morning north of our area.
Speaking of fog! We will have a chance of fog each night through Friday. It could be dense in some areas. Especially true of areas that received rain Saturday and Sunday.
Dry weather is likely through at least Saturday. Likely through Sunday, as well.
The one fly in the ointment is a possible cold front Sunday and Monday of next week. The GFS model has a cold front moving through the region. Other model data does not show that front. I will monitor trends.
For now, I have the forecast dry into the upcoming weekend. Looks like a nice weekend for outdoor festivals and other activities.
It will be warm towards the end of the week. Some areas may hit 90 degrees. The model data is in flux as to Sunday’s high temperatures. They have been swinging from the middle 80s to lower 90s. I will watch the trends. Either way, warm.
I could use your help! The National Weather Service needs your help.

FREE spotter training classes! EVERYONE is welcome. Most of these classes are online. We NEED more storm spotters. You can spot from home.
After the Mayfield tornado, everyone is acutely aware of our fall and winter severe weather threats. Often times, we don’t know what is happening on the ground (damage-wise) until we receive reports.
We need you. Please consider signing up for the FREE classes.

As a reminder, we typically see an uptick in tornado activity from mid-October through the end of November. Some of our deadlier outbreaks have occurred during the autumn and winter months.

Join us for Surviving the Storm. Thursday, September 29 at 6:00 PM at the Hickman County Extension Office.

Justin Jackson, Hickman Office of Emergency Management Director, will overview the Hickman County tornado damage and response.
Door Prizes (including five Midland 120 NOAA Weather Radios) and Light Refreshments are provided.
This free event is sponsored by the Hickman County Office of Emergency Management and Hickman County Extension.

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.
What is the NAO? Click here for more information.
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.
