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

Today through February 20th:  Severe thunderstorms are possible today.  The primary concern will be damaging wind and an isolated tornado risk.  Hail, as well.  The threat will end west to east as we move through the day.

 

.

Today’s Storm Prediction Center’s 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 size hail, and/or a tornado.

Weather Discussion

    1.  Thunderstorms today.
    2.  Turning colder.
    3.  Dry Friday through Sunday.
    4.  Rain chances next week.

 

Weather advice:

The primary weather concern today will be the risk of this morning’s thunderstorms.  These will linger into the afternoon over western Kentucky.

The activity will end west to east as we move through the day.

The atmosphere is unstable and some of the thunderstorms cold produce damaging wind gusts, hail, and even a tornado.

You can see the sharp difference in dew points.  Dew point is a measure of moisture.

For severe weather you usually want to see dew points of 58 and above.

The good news is that all of this will exit this afternoon and evening.

Colder air will move into the region behind the cold front.  As a matter of fact, temperatures will fall today from west to east.

Temperatures will fall into the 40s today over southeast Missouri and southern Illinois.  That cooler air will sweep eastward with time.

No weather concerns tonight into Sunday.  Cooler.

Additional rain chances arrive next week.  Some of the rain could be heavy, at times.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.

What should I take from these?

  1. The general idea and not specifics. Models usually do well with the generalities.
  2. 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.

You can see my final forecast at the top of the page.
