Scattered thunderstorms are expected to form along the Iowa/Missouri Border region this afternoon along a weak frontal boundary. These storms are expected to develop rapidly and be capable of producing large hail greater than ping pong balls, damaging winds greater than 60 mph, and could produce an isolated Tornado. With the rapid development of these storms it is highly recommended to keep your weather situational awareness elevated if you live in Northern Missouri this afternoon and evening. These storms are expected to form along a line and shift south around 8-10pm with some strong to isolated severe weather possible. The main threat after these storms start to move south will be isolated damaging winds and large hail. These storms are expected to weaken and dissipate before they reach the Missouri River with only some isolated showers and non-severe storms lingering into the early morning. Another round of storms is expected to push into the region overnight tonight moving through the KS/MO border region around sunrise on Thursday. These storms could be strong with damaging winds, small hail, and heavy downpours being the main threat as they push through.
