National Weather Service Shreveport LA 1136 AM CST Sat Dec 16 2017 .DISCUSSION... The 18z TAF discussion follows below. Very little has changed with the current forecast thinking. The 12z KSHV sounding shows a pronounced dry layer below 500 hPa. As southwesterly flow increases later today, the atmosphere should moisten from the top down. I would not be surprised if precip develops on radar this afternoon, but mostly evaporates before hitting the ground. Once the elevated precip begins, the lower levels of the atmosphere should quickly saturate, and the rain should reach the surface. Some minor updates were made to PoPs for this afternoon, and a few small edits were made to better match hourly trends. Updated text products have been sent. CNNational Ag.
