JOPLIN, Mo. - Under the normal July heat & humidity, we have seen random t-storms pop up across parts of the area this afternoon. They'll be around to start the evening out, but they'll also be fading away after sunset. Nothing severe is expected here, but it's a different story to the northwest of us.
Across northwestern Kansas, we have an upper level wave sneaking across the area at the jet stream level. In addition, a stationary/warm front has been parked across that corner of the state throughout the day. Both systems are allowing the heat, humidity and instability to spark scattered strong to severe t-storms. In fact, the slight risk of severe weather covers northwestern Kansas, northeastern Colorado and southern parts of Nebraska. Those t-storms for the rest of the afternoon and evening will be capable of large hail and damaging winds.
Up in the Northern Plains, another surface frontal system and upper level wave is actually coming across as the stronger duo of systems across the Lower 48 today. T-storms are ongoing across North Dakota while the Storm Prediction Center maintains a slight to enhanced severe threat for the rest of the afternoon & evening. Those t-storms will be capable of large hail, high wind gusts and some isolated tornadoes.
