Watch NBC Action News in HD for Kansas City's most accurate forecast!
Good morning everyone,
Thunderstorms on Monday evening were quite fascinating to watch develop, grow, and drift east and northeast. There was a complex of thunderstorms during the afternoon that formed near Topeka which produced yet another microburst with some damage, but no injuries. We have had a summer of microbursts, but fortunately that was the only isolated one on Monday. Those thunderstrorms never quite fell apart and ended up redevloping a couple of times as they drifted east. Right around sunset thunderstorms developed over the Kansas City metro area dumping very heavy rain and producing some rather vivid lightning. Here is a picture taken by Skylar Vance, one of our bloggers:

The models are finally catching onto what I showed last night on our weathercasts at 6 and 10 PM. There is a more well defined upper level disturbance moving our way from the western plains and it is directly aimed at our local region. Look below at the forecast map valid at 7 PM tonight from the 06z GFS:

As this wave approaches thunderstorms may continue to form in the diffluence ahead of the wave. There is a weak wind shift line also moving through. Our forecast high of 89 degrees yesterday was our 11th day in a row within 3 degrees as we hit it on the nose. Now, will the streak continue today? We had 77 for the high, but changed it to 80 degrees on our 10 PM newscast. It will likely depend on what happens with this developing morning complex of thunderstorms taking aim on the KC metro area.
Have a great morning and we will try to update the blog after the new data comes in.
