Let’s take a look at the set-up for later today and tonight.

First, we have strong and gusty winds today.  These are gradient winds.  What are gradient winds?  These winds are considered non-thunderstorm winds.  They are produced by rising and falling barometric pressure readings.  They are also caused by strong low level winds aloft.  These winds can be tapped into and brought down to the surface.

Winds of 20 to 40 mph will be possible today.

High temperatures today will top out in the 85 to 90-degree range!  Dew points will be in the 60s.  It will feel warm and humid.

.

Thunderstorm outlook.

As of this typing (12:20 PM), the weather radar looked like this.

You can see a line of showers and thunderstorms in Kansas, Oklahoma, and Texas.

This line of thunderstorms will continue to move east/northeast into the afternoon and evening hours.

There is a chance that some of the storms could be severe as they move into our western counties.  Our western counties would be near Poplar Bluff and down into the Bootheel.

Whether storms remain severe (as they move further east) is still a question.

The Storm Prediction Center (see above) has outlined portions of our region for a risk of severe weather later today and tonight.

Remember, a watch means to monitor updates.  A WARNING means to seek shelter.  A warning means to take action.

The best advice is to go about your business and monitor updated radars and forecasts.

Click images to enlarge them.

.

As you can see, future-cast radars have mixed ideas on how much of this activity survives into the overnight hours.  See the future-cast radars below.

In addition to this initial round of showers and thunderstorms, we may have another band or two of showers and storms form after midnight.

All of this muddles tomorrow morning’s forecast.

If we have widespread clouds and shower/storm activity before tomorrow afternoon then the risk of severe weather decreases tomorrow afternoon.

At this point, it is something I am monitoring.  The best advice is to monitor updates tomorrow.  I will, of course, be sending out app notifications.

Monday now appears to be shaping up dry.  That dry weather should last into Monday night.

Another system moves into the region on Tuesday and Tuesday night.  This system will produce additional showers and thunderstorms Tuesday into Wednesday.  Some of those storms could be intense.  Thus, monitor updates.

We are in peak tornado season.  Of course, we can have tornadoes year-round.  We typically see a peak in April, May, and June.  Then again in late October and November.

There will be some spin in the atmosphere over the next 24 to 36 hours.  Thus, monitor updated information.
