A dry northeast flow of air continues to run against a large area of precipitation to our west. The effect is for most of the precip to evaporate before reaching the ground. This process also saturates and cools the atmosphere until it is humid enough for the precip to make it all the way to the ground like it is near the Nebraska border. The featured plot shows relative humidity along with NEXRAD. You can see how much more humid it is where evaporation is occuring.
