Severe Thunderstorms Hit KC, What Is Next?

Good Saturday morning bloggers,

We broke through the ice last night ending what was becoming a dry month of June. Well, no longer as huge thunderstorms formed, fed by high dew points around 75 to 77 degrees Friday night.  These thunderstorms were really large and produced winds up to 88 mph over parts of northwest Missouri and northeast Kansas.

The above satellite pictures show what this ‘monster” turned into. These are the enhanced water vapor satellite pictures from 4:30 AM this morning.  There was one last thunderstorm that was potentially severe at 7 AM this morning over southern Johnson county Kansas.

Today’s Severe Weather Risk:



There is an enhanced risk of severe thunderstorms again today. Yesterday’s weather developed about as we expected with that developing area over northern Nebraska. It then grew into the strongest line of thunderstorms of the year in the Kansas City region and it about wore me out last night on 41 Action News.  Then, I awaken to this big thunderstorm this morning, so what is next?  We will be monitoring a developing and strengthening cold front. Moisture will be pooling ahead and near this front and with the rain that just fell, there may be dew points of 80 degrees which will provide tremendous fuel for any thunderstorms that form.


Before we see thunderstorms these 80° dew points will combine with highs in the 90s making for heat index values of 102° to 110°.  So, we are in an Excessive Heat Warning.


Let’s go through this crazy weather day as we have heat and thunderstorms in the forecast.

4 PM SATURDAY: A surface trough will be located near KC as the cold front approaches from the north.  At this time it will be sweltering with highs in the 90s along with the extreme humidity.  There should be no thunderstorms on radar.



7 PM SATURDAY: The cold front merges with the trough and we should see rapid thunderstorm development in our region.  Large hail and damaging winds are the main threats.  So, if you are out between 4 PM ad 7 PM be aware of rapidly changing weather conditions.



2 AM SUNDAY: The cold front will surge south and take the severe weather threat with it.  However, there will be lingering showers and thunderstorms behind the front and these will likely not be severe, but small hail is not out of the question.



FATHER’S DAY: The rain will end by 4-5 AM in the morning leading to a fantastic Father’s day forecast.  It will be mostly sunny, less humid and cooler with highs 75° to 80°. An amazing turnaround from the weather today.


Have a great weekend and keep an eye to the sky this afternoon and evening.

Gary and Jeff
