All severe weather concerns have ended for the region.
I am monitoring Wednesday into Friday for a rain and wintry mix event.
There remain quite a few questions about precipitation type and timing.
Monitor updates.
1:18 PM
Areas to the left of the white line are cleared from any severe weather concerns the rest of today.
12:30 PM
Line of storms is moving rapidly eastward. Winds of 45 to 55 mph are possible with the most intense thunderstorms.
Low end risk of a tornado this afternoon.
The threat ends once the line moves east.
11:48 PM
Tornado watch into this afternoon in the purple zone.
The threat ends as the line moves east.
11:40 AM
Severe risk is over to the left of the white line
11:30
Most guidance is showing the mid to late week event being a rain event. Uncertainty remains on track and intensity of the system.
11:15 AM
Severe risk is over to the left of the white line
10:45 AM
These storms are producing 30 to 45 mph wind gusts as they move over any given location.
The storms are gaining some strength. I can’t rule out some 50 mph gusts over coming hours. Perhaps higher.
The line is expanding.

10:15 AM
A line of storms has formed in eastern Arkansas. It is moving east/northeast at 60 mph.
Some of these storms could produce strong and gusty winds.

The National Weather Service defines a severe thunderstorm as one that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.
Today: Thunderstorms are possible today. A few of the storms could produce damaging wind gusts and even isolated tornadoes. Make sure your www.weathertalk.com account is up to date. I will be sending out app/text messages.
The time frame of concern will be 10 AM to 4 PM. The line of storms will push west to east at speeds of 60 mph.
Individual storm cells would be east/northeast.
Tuesday through Saturday: I am monitoring a system Thursday into Friday. Parts of our region could be in the warm sector. That would mean additional thunderstorm chances. Confidence in this remains low.

Today into Tuesday night:
Yes, it is winter. Today, however, it may feel more like spring. Not all that uncommon in our region. We seem to have a few of these days each winter.
Those wanting snow will not be receiving any today.
The big weather story today will be the risk of a few severe thunderstorms and warm temperatures (for some of us). Gusty winds will develop today, as well.
The main area of concern will be the darker green zones. That would include southeast Illinois, western Kentucky, western Tennessee, and the Missouri Bootheel.
Areas to the right of the yellow line may have a slightly better chance of severe weather. Either way, the main concern will be damaging wind gusts with a line of thunderstorms. A tornado can’t be ruled out in bowing line segments or any storms that form ahead of the main line of storms.
The light green zone would mainly be where lightning is possible.
A cold front is positioned to our west. A warm front is passing through the region.
The jet stream is racing across our region today. The low-level jet will approach 80+ mph later this morning into this afternoon. The upper-level jet will be roaring overhead, as well. All of this wind energy will help produce the potential of damaging wind gusts and tornadoes.
Here is the 850 mb map. This is about 5000′ aloft. These are strong winds.
Wind shear the turning of winds with height or the increase of wind speed with height will be present today. Wind shear is one ingredient when forecasting severe thunderstorms.
No shortage of wind energy today.
Here is the 300 mb jet stream map.
Here is the 500 mb jet stream map
Warm and moist air is streaming northward from the Gulf of Mexico.
The warmest weather today will be across portions of southern Illinois into Kentucky and Tennessee.
Temperatures will pop into the lower to middle 60’s ahead of the cold front.
Dew points will also be on the rise. Dew point is a measure of moisture in the atmosphere. The higher dew points will help set the stage for thunderstorms.
PWAT values are high for this time of the year. There is no shortage of moisture for thunderstorms to tap into.
Here is the morning PWAT value map. These are well above the seasonal norms.
7 AM PWAT values
Check out the temperature animation for today.
A warm surge of air ahead of the cold front. That will help set the stage for our thunderstorms.
Dew points will also be on the rise today. I generally look for 58+ dew points when forecasting severe weather. Portions of our region will have those numbers today.
Future-cast radar from the 3K NAM model guidance. You can see the formation of a line of storms later today. That is called a QLCS.

Our next precipitation maker
Many models are showing the Wednesday into Friday event as mostly rain. This remains a possibility. Confidence isn’t all that great in the final details. Continue to monitor updates.
Questions in the forecast begin Wednesday into Friday as another system develops to our southwest.
I am closely monitoring a southern storm system that will bring rain and perhaps a wintry mix south of our region.
Some of the guidance is showing copious amounts of moisture with this event. The question will be the track of the low and upper-level low-pressure center. That will be key to our regions forecast.
Most of the guidance over the past 24 hours has brought precipitation into our region.
There has been a northward shift in all of the guidance packages. That does increase confidence that we will have some type of precipitation in our region Wednesday into Friday.
Perhaps the heaviest precipitation would be Thursday and Friday.
Here is the NAM guidance is showing. It does not go out far enough to cover the entire system.
First, here is the future-cast radar from the NAM guidance. One model of many.
Here are the temperatures via the NAM model.
You can see it here on the GFS model guidance. The GFS has been trending northward.
There are two different GFS models. A new one will replace the old one soon.
This is the old version.
They both look similar.
Notice there is a wave of precipitation on Wednesday and Thursday. The bigger system then develops Thursday night into Friday.
You can see the blue colors. That represents snow. Green, dark green, yellow, and orange represent rain to heavy rain.
There remain questions above temperatures in our local area. The GFS would mostly be a wintry mix changing to rain.
A band of snow develops on the GFS from southwest Missouri into central Illinois Thursday night and Friday.
One model of many. All models show something a little bit different. Confidence will increase over the coming 48 to 72 hours on a final solution.
Here is the new version of the GFS. Not much different from the old version.
Here is the Canadian model.
The Canadian model is colder vs the GFS. It shows more of a wintry mix and snow solution locally.
The EC model shows mostly rain in our region. It keeps snow to our west.
This is the EC model snow totals forecast.
Let me show you some ensemble guidance.
Here are the GFS ensembles
There has been a move towards two waves of precipitation. On Wednesday night/Thursday and a bigger push Thursday night and Friday. This is a change from previous forecast updates.
Temperatures remain a question mark. We could see a wintry mix changing to all rain. Confidence in the details will remain low.
Click to enlarge
Some of them are showing snow in our region Wednesday night into Thursday night. The colors represent snow totals.
Again, the idea is to see if there is an agreement in the ensembles..
Some show snow locally and some do not.
There remains a lower than normal confidence in the Wednesday through Friday time-frame.
Here are the EC model ensembles. Another model.
Temperature Anomalies
Let’s look at the temperature anomaly forecast map from the GFS model guidance.
I will keep showing you this graphic animation over the coming weeks.
Red colors indicate above normal temperatures. Blue colors represent below normal temperatures.
The time-stamp is located in the upper left portion of the map animation.
The models have been swinging back and forth on the subject of warm vs cold.

I bring these to you from the BAMwx team. They are excellent long-range forecasters.
Remember, long-range outlooks are always going to be a lower confidence level than short-term forecasts. It is not an exact science. There are many variables that determine the eventual outcome of a long-range forecast.
Normal high temperatures for this time of the year are around 44 degrees.
Normal low temperatures for this time of the year are around 26 degrees.
Normal precipitation during this time period ranges from 0.60″ to 0.80″
This outlook covers December 27th through December January 2nd

Did you know that a portion of your monthly subscription helps support local charity projects?
You can learn more about those projects by visiting the Shadow Angel Foundation website and the Beau Dodson News website.
I encourage subscribers to use the app vs regular text messaging. We have found text messaging to be delayed during severe weather. The app typically will receive the messages instantly. I recommend people have three to four methods of receiving their severe weather information.
Remember, my app and text alerts are hand typed and not computer generated. You are being given personal attention during significant weather events.
