An excessive heat advisory has been issued for most of the region.   Portions of the region are in an excessive heat warning.

It’s going to be hot.  That is the bottom line.  Especially, Thursday into Friday.  Perhaps Saturday.

Temperatures will vary based on cloud cover and any thunderstorm activity, keep that in mind.

Forecast Discussion

Today’s Average Regional Forecast Numbers

Temperatures will vary based on cloud cover and precipitation.  Keep that in mind.

Tracking thunderstorms and heat.

Thursday was one of the more extreme weather days in quite some time.

Check out over 500 severe weather reports.  Mostly from a derecho that moved through Missouri, Iowa, Illinois, Indiana, and Kentucky.

Double click images to enlarge them.

We had heat index values, at one point, that ranged from 122 degrees in southeast Missouri down to 68 degrees in Owensboro.  At the same time.

We had some locations that received three to seven inches of rain.  There were reports of 80 mph wind gusts with golf ball size hail.

Some locations reached over 100 degrees.  While other locations were in the 60s.

Here was the heat index map late in the afternoon.

Remember, I told you we would have extreme temperature gradients with wildly different numbers depending on clouds and thunderstorms.

Multiple MCS’s tracked across Missouri, Iowa, Illinois, Indiana, and Kentucky.  Many of those MCS”s produced widespread wind damage, hail, and flash flooding.

No less than three MCS’s tracked through our northeastern and eastern counties.  These storms produced numerous reports of wind damage, hail, and flooding.

This is what those MCS’s looked like at one point during the mid-afternoon hours.  The IR satellite showed very cold cloud tops (the red colors).  These are severe thunderstorms.

Thursday was a crazy weather day in our region!

Here were the radar estimated rain totals from yesterday.  An extreme event with some locations topping SEVEN inches of rain!

We have several days of very active weather ahead of us.

The pattern has been active and will remain active in next week.  We could have multiple rounds of thunderstorms.  Some of the thunderstorms will be severe with damaging wind, hail, and flash flooding.  Lightning, as well.

The Storm Prediction Center has outlined our region for a risk of severe weather today, tomorrow, and Sunday.

Perhaps the highest risk will be tomorrow.

Either way, supercell thunderstorms and lines of thunderstorms will likely deliver much needed rainfall to the region.  Some areas, however, will receive too much rain.  Same as yesterday.

Flash flooding will be a concern in some areas.   One to three inches of rain per hour will be possible in the most intense thunderstorms.

Avoid flooded roadways.

Stay weather aware over the coming days.  Each day will be a bit different on the timing of the thunderstorms.  This will need to be monitored.

Monitor your Beau Dodson Weather app for the most up to date messages and alerts.

It will also be hot today and tomorrow.

Highs today could top 100 degrees in some areas.  Heat index values of 100 to 115 degrees.

Highs Saturday could approach the middle and upper 90s (depending on cloud cover and precipitation).  Heat index values will once again jump above 100 degrees.  Muggy air.

This can be a dangerous heat for the young and elderly.  It can make for dangerous work conditions for those who have to work outside, as well.

Use caution, as always.  Know the symptoms for heat related illnesses.

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

Today through April 18th:  A couple of the Saturday afternoon and night thunderstorms could produce damaging wind and hail.  The tornado risk is low, but not zero.  Mainly over Missouri for the tornado risk.  The line will weaken with time as it moves farther east.

 

.

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.
