Good afternoon bloggers,
Watch NBC Action News at 5, 6, and 10 PM for the most accurate and best severe weather coverage tonight!
The high risk has been shifted a bit west, as expected, but we still have a strong potential for some night-time severe thunderstorms. Look at the surface map at noon today. There is a very strong 988 MB (29.17") surface low near the Kansas/Nebraska border. The most likely spot for strong tornadoes will be closer to this surface low.

There is a dry line just now strengthening, and it will become better defined in the next few hours, over southwestern Kansas. As this punches out, severe thunderstorms will break out, and they have already broken through the weakening cap. PDS tornado watches have now been issued to our west. PDS stands for Particularly Dangerous Situation. Look at the risk maps below, just issued from the Storm Prediction Center:



This is the strongest and most widespread outlook I have seen in a long time. The first thing to notice is that we are on the eastern edge of most of these higher risks. Severe thunderstorms are now breaking out. They will form into a line, a few supercells, and then the event will evolve into possible bow echoes tonight. I think our main threat will be from the developing bow echo between 9 PM and 2 AM tonight.
We will know a lot more about our potential for severe weather by the evening newscasts. Right now, it still appears we have almost no chance of any severe weather until after sunset. So, just relax, and we will all watch this together. I am supposed to be off today, so Jeremy Nelson will be doing the 5 and 6 PM newscasts. I will be coming in this evening as the severe weather approaches. Stay with NBC Action News, and we'll keep you advised.
