There is a chance for a few severe thunderstorms across KS on Sunday, assuming that we break the cap - which is possible, with the latest model runs showing precip breaking out across the southeastern half of KS. Favorable veering profiles and extreme instability suggest a threat for isolated supercells - associated with very rich boundary layer moisture, with widespread >70 Tds across central/eastern KS. Therefore, assuming we get enough covergance along the dryline/trough... A few isolated supercells will be quite possible. I haven't looked at anything much at the moment, but SUN was brought to my intention in another thread... I'll make a more detailed FCST later.
