Its sfc reflection, a cold front, is through the region now, and what little instability is left near the AR/TN borders will quickly wane by late afternoon. Thus, lingering showers are in the near-term forecast, with the highest PoPs in the sern sector. The fact that the shrtwv is now progged to dig/strengthen tonight, and eventually become a closed low over the Carolinas, led to more pessimistic timing for clearing of clouds from nw to se.
