Thursday to Thursday
1. Is lightning in the forecast? Yes. Lightning will be possible today. I am monitoring next Monday night and Tuesday for lightning, as well.
2. Are severe thunderstorms in the forecast? Possible. A few storms could be severe today. The primary concern will be damaging wind gusts. A tornado can’t be ruled out, but that will be highly dependent on how much instability develops.

The NWS officially defines a severe thunderstorm as a storm with 58 mph wind or greater, 1″ hail or larger, and/or tornadoes
3. Is flash flooding in the forecast? Monitor. Locally heavy rain will be possible today. A few ditches and streams could flood. Field flooding, as well. Avoid flooded roadways.
4. Will the wind chill dip below 10 degrees? Yes. Thursday night.
5. Is measurable snow or ice in the forecast? Monitor. A light wintry mix is possible over northern portions of southeast Missouri and northern portions of southern Illinois later this afternoon. Any accumulation would be light.
I am closely monitoring next Wednesday and Thursday. Some data indicates there may be enough cold air in our region for a wintry mixture of precipitation. Still plenty of time to monitor that portion of the forecast.
6. Will the heat index top 100 degrees? No.

Today through February 22nd The LIVE severe weather blog has been activated. You can view that at this link https://wp-talk.weathertalk.com/live-severe-weather-blog-february-17-2022/
Thunderstorms could become severe later this morning and afternoon across portions of our region. The risk is highest from the Missouri Bootheel into Kentucky and Tennessee. The further south you travel, the higher the risk of experiencing severe weather.
The risk is lower as you move north through southeast Missouri and southern Illinois.
The primary concern will be damaging wind gusts. A secondary concern will be tornadoes. The tornado risk is highly conditional on surface based CAPE developing. CAPE is basically energy that storms tap into. Monitor your Beau Dodson Weather app.
.
.
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
-
- Strong gradient winds today. Winds could top 50 mph.
- Locally heavy rain today. Avoid flooded roadways.
- Severe weather risk today will include damaging wind and possibly a tornado.
- Much colder air pushes into the region later this afternoon and evening.
- Additional precipitation chances next week.

Weather Discussion
A busy 12 to 24 hours of weather ahead of us.
Let’s break it down.
Gusty winds today.
We will have strong and gusty gradient winds today. Gradient winds are caused by rapidly falling and rising barometric pressure. Your home barometer will be falling today.
Low pressure will push into our region this afternoon and depart this evening. This is what will cause the pressure change.
Gradient winds are caused by these changes in pressure.
Widespread 15 to 30 mph winds are anticipated today with occasional gusts into the 40 to 50 mph range (perhaps isolated higher numbers).
These gradient winds could bring down tree limbs. Power outages can’t be ruled out, as well.
The winds will begin to subside tonight.
.
Locally heavy rain today.
We are waking up to widespread rain. Showers and thunderstorms cover much of the radar.
Radar at 7 AM showed this. Quite a big of rain in the region. Some thunderstorms, as well.
Rain will continue on and off throughout today.
Some of the rain will be heavy. If thunderstorms train over the same area then some areas could easily receive two to three inches of rain.
This heavy rain could cause ditches to overflow and creeks/streams to rapidly rise. Some flood warnings are certainly possible.
Avoid flooded roadways, as always.
Rain will taper off late this afternoon and evening. Ending this evening/tonight.
The rain may briefly change to a wintry mix over our northern counties. Little or no accumulation.
.
The risk of severe thunderstorms today.
The LIVE severe weather blog has been activated. You can view that at this link https://wp-talk.weathertalk.com/live-severe-weather-blog-february-17-2022/
The biggest concern with this system has been the potential of severe thunderstorms.
This has been a difficult system to forecast. We are right on the edge of better instability to our south and less instability to our north.
Instability is necessary when forecasting severe thunderstorms.
The risk of severe weather will be greater as you travel southward today. The risk will be lower as you travel northward.
At this time, it appears the area of low pressure is going to end up tracking fairly far south compared to what models had been showing the last four or five days. This is one reason that I have been hesitant to pound the severe weather drums. Not until confidence increased on the final outcome.
The highest risk of severe weather is going to run from the Missouri Bootheel into western Kentucky and northwest Tennessee. The risk may be a tad higher from the Kentucky/Tennessee border southward.
Areas to the north could also see severe weather, but the risk appears lower.
The primary concern will be lightning and damaging wind gusts.
Wind shear with this system is near the top of the charts. Wind shear is the change of wind direction and speed as you move up into the atmosphere.
There is no lack of wind shear with this event.
What is lacking is CAPE. CAPE is basically energy that thunderstorms tap into to become severe.
This is a low CAPE set-up. That is typical for February. High shear and low CAPE.
It does not take much CAPE to cause severe thunderstorms during the winter months. The shears makes up for the lack of CAPE. It does, however, take some CAPE.
I will be monitoring CAPE throughout today.
Plan on some severe thunderstorm warnings later today/this afternoon. I can’t rule out tornado warnings, as well.
Any thunderstorms that can become surface based could spin. Thus, a tornado is certainly not out of the questions.
Storms will be moving east/northeast in excess of 50 mph. Fast moving storms. This will not give you a lot of time to seek shelter if a tornado were to develop.
Know your families safety plan in the event severe weather develops.
.
Friday into Sunday night.
Dry conditions are anticipated Friday through Sunday. Cold Friday but then a slow moderation in the temperature department as we move through the weekend.
.
Active next week.
Guidance indicates a train of storm systems over the next 10 to 14 days.
Rain is likely to redevelop in the region Monday and Monday night. Becoming widespread, at times. This rain will continue into Tuesday.
I am watching another storm system next Wednesday and Thursday. This is in the long range portion of the forecast and confidence in that system developing is low. For now, at least.
There may be enough cold air for the system Wednesday and Thursday to be a wintry mix. Again, this is in the long range and confidence in the details is not great.
Monitor updates moving forward.

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.
