1. The inflow of warm, humid air will hit the front from Oklahoma to Kentucky. Within that area as shown on the map, storms may contain damaging wind gusts and large hail. With the air getting cold aloft, hail may be the bigger factor.
2. Models are still not in good agreement on the moisture from Miriam into Texas. Euro is much wetter while the GFS has backed off. Our thinking is that low-level center from Miriam goes out to the Pacific while the moisture streams off to the northeast into Texas.
It's going to be a stormy period across the country, but the models seem to differ on the outcome.
The storm that is coming into the Plains will produce a wide range of weather including snow, ice and flooding rains.
