Good morning bloggers,
What a day! Morning thunderstorms created a large rain cooled air mass that almost prevented the afternoon thunderstorms from being generated. But, that is not what happened as the atmosphere destabilized just enough for intense thunderstorms to develop later in the afternoon and evening. The evening thunderstorms targeted Kansas City and one of the cells had some interesting lowerings right over downtown. The late afternoon thunderstorm dumped an inch of rain on KCI Airport, so they finally caught up with the rest of us on rainfall with 1.72″ of rain yesterday.
Take a look a this storm system on the water vapor satellite picture taken at 10 PM last night:
As the late afternoon thunderstorms were developing, the morning activity developed a westward moving outflow boundary which acted like a cold front moving west. Take a look at all of the activity on the 4:45 PM visible satellite picture. The thunderstorms would get a boost from that westward moving line of cooler air:
Take a look at this closer version of the 4:45 PM satellite picture:
Just 15 minutes later the line was about to interact with the developing supercells. When that wind shift line entered the thunderstorms the cells ignited and got stronger and started producing tornadoes. I believe that this line played a factor in the strengthening thunderstorms. Here is a look at the 5 PM Satellite picture:
Tornadoes were about to touch down, and by 6:15 PM we already experienced a few tornadoes on the southern part of our viewing area. You can also see the dust spreading east behind the dry line/Pacific front. This is shown in that arcing line across central Kansas:
Here are the severe weather storm reports from yesterday:
The upper low will be spinning east today and wrap around moisture will rotate some rain south into our area later tonight and Tuesday. There is also still a chance of a frost or even a light freeze later this week . We will go over the details on 41 Action News today and tonight. Thank you for spending a few minutes of your day reading the Action Weather Blog.
