As cell in Harper Co, OK is topping at 50,000 ft and clearly broken above the LFC and returning 55 dbz, will go ahead and start a NOW thread. Over the past hour, baroclinic disturbance and extreme heating at the surface along a E/W-oriented stationary front/ wind shift line has exhibited a build in instability parameters which holds some potential for severe over N OK, S KS, and points downstream. Given seasonal norms, hopefull some interest in this developing weather.
