Area Forecast Discussion National Weather Service Memphis TN 406 PM CDT Sun Jun 23 2019 .DISCUSSION...GOES-16 Water Vapor Satellite and regional WSR-88D radar trends indicate a Mesoscale Convective System moving over portions of Arkansas, Southeast Missouri and the Missouri Bootheel this afternoon. A line of showers and thunderstorms with a few scattered showers and thunderstorms just ahead of the line extend from the Missouri Bootheel back into East Central Arkansas. As of 3 PM CDT, temperatures across the Mid-South are in the lower 90s where rain free conditions are still occurring, and 70s where showers and thunderstorms have already occurred this afternoon. Short term convective trends are the primary concern in this afternoon's forecast issuance. The aforementioned line of showers and thunderstorms with a cold pool will continue to push across portions of the Mid-South into this evening. Surface based CAPE values in excess of 3000 J/kg and 0-6 km Bulk Shear values approaching 35 kts will support a potential for damaging winds as the primary severe weather threat. Hail is not as much of a concern as wind as freezing levels remain quite high. Precipitable water values around 2 inches will also support localized heavy rainfall, especially with training thunderstorms. Models indicate the potential for showers and thunderstorms will continue across the Mid-South this week with another shortwave trough moving across the area on Tuesday and a warm, moist, and unstable airmass remaining in place across the Lower Mississippi Valley. Overall shear is expected to remain weak with pulse type thunderstorms being the most probable convective mode in a high CAPE, low shear environment. In this scenario, the best shower and thunderstorm chances would typically occur during the afternoon- early/mid evening hours. Overall temperatures this week will remain nearly similar over the next 7 days with highs in the 80s to approaching 90 degrees and lows in the upper 60s to lower 70s. CJC && .AVIATION... /18z TAFs/ Isolated thunderstorms are developing across the Mid-South early this afternoon with a more organized line of storms moving out of the Ozarks. This complex of storms is expected to march southeast across the CWA during the late afternoon and early evening hours, resulting in thunderstorms on station and gusty outflow winds. Additional convection is possible overnight, although confidence is lower on the timing/extent of this second wave. Low clouds are expected to develop late tonight and continue into Monday morning with generally dry weather tomorrow after morning precipitation moves east. MJ && .MEG WATCHES/WARNINGS/ADVISORIES...
