A large upper trough is close to Colorado today with several short wave troughs rotating around it. As has been the case in the last couple of week abundant tropical moisture is starting to move north across the Plains with widespread showers and thunderstorms across parts of the southern Plains, with flooding becoming a major issue in places.
Here in Colorado an area of low pressure is creating a backed surface wind, leading to supercell wind profiles. However, the main question is how much instability will develop. At this stage areas south-east of Limon look better for this although the better backed surface flow may well develop to the north of Limon, aided by the Palmer Divide. We'll probably hang around in Limon for a bit until things become a bit clearer, if indeed they do!
