Good Saturday morning bloggers,
It was a crazy 48 hours for our NBC Action News weather team. Wednesday night, powerful supercell thunderstorms developed from central Kansas northeast into Iowa with deadly results. I was on the air 11:45 PM when I showed the tornado on ESP radar. It was so obviously a tornado signature near Soldier, Kansas (north of Topeka). A mobile home was picked up and tossed 225 yards. A man was killed in that mobile home. Manhattan and Chapman, KS were hit very hard. This car was caried 1/4 mile by the tornado, a great example of why you should get out of the car and lie in a ditch.

Then, on Thursday evening a line of thunderstorms developed on a weakening front, just northwest of Kansas City. Conditions weren't as favorable for tornadoes, but we caught these tornadoes developing on the air live, as you can see on the link below. There was a shelf cloud that formed in a bowing out cell near Lawrence. A strong circulation formed just northwest of the bow, and we had Skytracker (our helicopter) positioned perfectly to catch the violent rotation, but the tornado was very weak on the ground, thank goodness. Here is the link to how we experienced it live Thursday night:

Our next chance of thunderstorms is showing up for tomorrow. A cold front is being generated to our northwest today as the weather pattern transitions into northwest flow. Moisture will be flowing back in from the Gulf of Mexico and our dewpoints will likely rise back up to the magical 70 degrees or higher. I say magical, because when you have a 70 degree dewpoint or higher and a front is moving through, then it is almost a certainty that there will be thunderstorms with very heavy rainfall amounts. Look below at the front forecasted to be northwest of us on Sunday morning:

Thunderstorms should form by early afternoon as the moisture meets the front. Then the thunderstorms should track southeast. There is a cap that may create a strong western edge to these thundertorms, but it is weak, so I think that our viewing area is the target for this activity on Sunday. Here is the rainfall forecast from this mornings NAM model:

Some severe weather is possible, but the main threat will be strong winds along the leading edge of a developing complex of thunderstorms. As the thunderstorms first develop, large hail will also be a threat. Right now, I am timing this to develop early Sunday afternoon, and then race through our area by evening, reaching Kansas City around mid to late afternoon on Sunday. We will be watching this for you.
One last thing today. There is a picture circulating around that is not real. This is NOT real. Ths well formed supercell thunderstorm appears to be on the ground. Notice there is no debris, and a lot of other problems with this picture. It is being described as the Iowa tornado:

Have a great day!
