Seven Day Hazardous Weather Outlook

1. Is lightning in the forecast? YES. Lightning is possible today into Tuesday. I will monitor next Sunday into Tuesday.

2. Are severe thunderstorms in the forecast? YES. Severe thunderstorms are possible Monday afternoon and night. Some risk on Tuesday morning, as well. We will need to monitor the track of the cold front Tuesday. It is possible that a few storm redevelop during the afternoon hours on Tuesday. Once the cold front exits your county, then the threat of severe weather is over.

3. Is flash flooding in the forecast? MONITOR. Any slow moving thunderstorms could cause locally heavy rain. If a couple of storms train over the same areas, then the risk of flash flooding will increase.

4. Will non-thunderstorm winds top 40 mph? NOT AT THIS TIME. Gusty winds are possible today into Tuesday. For now, I kept them below 40 mph.

5. Will the heat index exceed 100 degrees? NO.

6. Will the wind chill dip below 10 degrees? NO.

7. Is measurable snow and/or sleet in the forecast? NO.

8. Is freezing rain/ice in the forecast? NO.
Freezing rain is rain that falls and instantly freezes on objects such as trees and power lines Freezing fog possible, as well.

Fire weather risk level.

Monday through Monday night: 4. Low risk.
Tuesday: 3. Very low risk.
Tuesday night: 4. Very low risk.

Fire Weather Discussion

Today should be mostly dry, with a southwest breeze and mixing heights up to around 3000 ft. This should lead to fair to good smoke dispersion through the day. Thunderstorms will approach tonight into Tuesday followed by a cold front that will sweep much cooler conditions and lower relative humidity values into the area.

A Haines Index of 6 means a high potential for an existing fire to become large or exhibit erratic fire behavior, 5 means medium potential, 4 means low potential, and anything less than 4 means very low potential.

Weather advice:

Do you have any suggestions or comments? Email me at beaudodson@usawx.com

Make sure you have three to five ways of receiving your severe weather information.

Weather Talk is one of those ways.

** NEW SERVICE ** I have partnered with WeatherCall to bring you an added layer of protection.

We also have a new service to compliment your www.weathertalk.com subscription. This does NOT replace www.weathertalk.com It is simply another tool for you to receive severe weather information.

I use it myself. I encourage everyone to have 3 to 5 ways of receiving their severe weather information. All sources can fail and the more sources you have, the better prepared you will be in the event of severe weather warnings.

WeatherCall will call your cell phone or home number if your home is in a tornado or severe thunderstorm warning. It only calls you if your home is inside the warning polygon. If you are outside the polygon it will not disturb you.

Beau’s Forecast Discussion

** Severe Weather Event Increasingly Likely **

The concern?

Damaging wind and golf ball size hail. A few tornadoes can’t be ruled out, as well. Locally heavy rain and lightning.

When?

We are focused on late Monday afternoon into the wee early morning hours of Tuesday. Peak time-frame will be 10 PM tonight to 2 PM Tuesday. Some of the thunderstorms may continue into Tuesday afternoon over southeast Illinois, Kentucky, and Tennessee.

The risk will first arrive over southeast Missouri and northern portions of southern Illinois this evening into the overnight hours.

It will then move east across the region late tonight into tomorrow.

A second round of storms will develop Tuesday mid to late morning into the afternoon hours. That round would mainly be southern Illinois into Kentucky and Tennessee. More likely east vs west. Some of those storms could be severe, as well.

Where?

See the graphics. There is a risk area-wide later today/tonight into tomorrow morning. Then, the risk shifts a bit more east tomorrow.

Certainties

Thunderstorms will occur. Some will be severe. Severe thunderstorm and/or tornado watches will be issued. Some warnings will be issued.

Uncertainties

There are questions about the exact timing county by county. Models are not handling this situation very well. It appears a few storms could develop as early as this afternoon over our northern counties, but most likely the bulk of this event will be very late tonight into Tuesday morning.

There are questions about coverage. Some data shows a line of storms moving into the region late tonight, but then it falls apart leaving a boundary. New storms form along the boundary tomorrow.

Other data shows a solid line of storms sweeping across the entire region.

Confidence in the coverage is lower than usual. Monitor updates.

Call to action

Make sure you have 3 to 5 ways of receiving severe weather information.

The www.weathertalk.com Beau Dodson Weather app is one of those ways.

We have a new service that CALLS your home phone of cell phone if you house is in a tornado or severe thunderstorm warning. You can subscribe to that here https://weathercallservices.com/beau-dodson-weather

I have partnered with WeatherCall to bring you this service.

A weather radio is a great source of weather information.

Other local television weather apps.

Make sure your WEA is on. Google Android or Apple WEA severe weather alerts. How to turn on my WEA. Google that.

Outdoor sirens can be a source for those outside.

Forecast Discussion.

The risk of severe weather continues to increase Monday afternoon and especially Monday night.

We are in a level one, two, and three risk across the region.

I encourage you to not get caught up in the colors. Weather doesn’t always follow our nicely drawn maps and color grids.

A tornado in the level one zone is the same as a tornado in a level three zone. The damage is the same. Thus, let’s not focus on the colors. Focus on the forecast.

Most of our regions EF3 and greater intensity tornadoes have occurred in level one, two, and three risks.

The forecast is for severe thunderstorms to develop Monday afternoon into early Tuesday morning. Tornadoes, damaging wind, and large hail will be a concern.

If supercells form, then some of the hail could reach golf ball size or perhaps even larger.

Supercells tend to be scattered vs a solid line of storms. A solid line of storms would be more likely to produce damaging wind and short-lived tornadoes.

A squall line looks like this

Supercells look like this. Supercells are discrete.

Supercells tend to produce longer tracked tornadoes, higher damaging wind gusts, and larger hail.

Early on, supercells appear possible. Then, a line of storms should form.

The bulk of our regions tornadoes occur in level one, two, and three risk zones. So, again, don’t get too caught up in the colors.

The color levels are good for guidance, but don’t tell the entire story. I try to remind everyone of this during every event.

For example, the Harrisburg EF4 tornadoes, several years ago, was in a level two risk. A slight risk.

Graphic one shows you the Storm Prediction Center’s official severe weather outlook. Adjustments are still possible. They have changed this outlook three times in the last 24 hours.

Which is one more reason not to get too caught up in the colors.

If storms train over the same area, then some brief flooding concerns could develop. Avoid flooded roadways, as always.

There will be quite a bit of wind shear aloft with this event. Wind shear is the turning of wind with height and the increase in wind speed with height.

This is an ingredient for severe thunderstorms.

Dew points will rise into the 60s. That is plenty of moisture for severe thunderstorms to tap into.

CAPE values (instability) will rise into the 500 to 1500 range Monday afternoon and evening.

All of those are ingredients for severe weather.

The Paducah, Kentucky, National Weather Service made the fifth graphic.

Double click graphics to enlarge them.

We will have some lingering light showers Wednesday.

Turning colder Wednesday into Friday. I can’t rule out some frost and or a light freeze this week, again.

Dry Thursday into Saturday.

This outlook covers southeast Missouri, southern Illinois, western Kentucky, and far northwest Tennessee.

Today’s Storm Prediction Center’s (SPC) Severe Weather Outlook

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 or larger size hail, and/or a tornado.
