Good morning bloggers,
There is a spinning area of rain, heavy rain, near the Nebraska/Kansas border northwest of Manhattan, KS. This is just another area of rain that will likely not affect our local area. At least it has cooled off a bit with highs near 90 degrees for All Star week.
It was an interesting weekend of weather! While Kansas City, once again, was getting missed by thunderstorms, strong thunderstorms were developing over the Lake of the Ozark’s. I just happened to be there this weekend visiting some friends for one night. We went out on the boat, about eight of us, and it was a sunny start to the day. A few clouds were beginning to form, initially just high based altocumulus clouds. I told everyone that there was a chance of thunderstorms and possibly a microburst and we have to pay close attention to the sky. This first picture was taken as the first clouds were developing.
The high based altocumulus clouds were just developing around noon when we went out and here is a picture I snapped. I was convinced at this moment that thunderstorms would form over the lake. I just didn’t know if I would get to experience one of them?
Only 3o minutes went by and lower cumulus clouds began developing. The first thunderstorms formed by around 1:30 PM and then by 4 PM I was experiencing a thunderstorm with lightning just a few feet away. Here is a picture I snapped around 4:30 PM during the thunderstorm. This (rain) is something I haven’t seen in Kansas City in weeks.
I knew there was a chance that these thunderstorms could produce some microbursts. I had come back to the lake house that I was staying at, and suddenly there were lightning strikes, thunder, and the rest of the people I was staying with came back to the dock. They had experienced the microburst on the water. They were in the water when the wind gusted, as they described, to around 45 mph or so. Everyone scrambled into their boats. While they were experiencing the weaker microburst, there was a stronger one a bit farther to the east and then another one over Truman lake that did cause some minor damage to docks, and a few boats.
Lynn Worthington took this next picture at the Lake of the Ozark’s yesterday showing the microburst in progress. The rain shaft is blasting down to the ground near Timberlake Village, the Lick Branch Cove at the 5MM of the Lake of the Ozarks. Thank you Lynn for sharing this on Facebook. This is just two miles due west of Sunrise Beach. I was located farther west near Laurie, MO. This picture shows two rain shafts, one on the left side, and another not the right edge of this picture. You can actually somewhat see one of the microbursts on the right side of this photo where that rain shaft had reached the ground. The left edge of the rain has spread out from the main rain shaft indicating a wind blowing away from the main area of rain. The bases of these thunderstorms, or cumulonimbus clouds, were around 8,000 to 10,000 feet up. These are very high bases, which allowed for the rain falling to evaporate slightly on its decent to the ground. The wind speeds accelerated as it blasted to the ground and just barely became strong enough to be called a severe thunderstorm with nearly 60 mph winds:
The first heat wave of summer lasted eleven days. The cooler air arrived Sunday with highs near 90 in most areas. A few spots had highs in the 80s yesterday due to the cloud cover. Unfortunately the heat will be building back over the plains by next week. For now, the anticyclone has shifted to the west:
This anticyclone will be moving east again soon. Let’s enjoy the slightly cooler air while it is here this week, which is great timing for the All Star Game activities going on. Thank you for spending a few minutes of your Monday reading the Action Weather Blog.
