149 FXUS64 KJAN 020016 AAA AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 716 PM CDT Sat Jun 1 2024 ...New AVIATION... .DISCUSSION... Issued at 315 PM CDT Sat Jun 1 2024 Through Sunday: An active weather pattern will continue in the near term as rain and thunderstorms are expected to redevelop later on in the evening. Short term guidance continues to show a shortwave disturbance developing a convective complex in the southwest and pushing the previously mentioned complex into the ArkLaMiss region during the evening/overnight hours. With instability still in place (MLCAPE values near 2000 J/kg, lapse rate between 6-7 C/km) and decent precipitable water values near 1.5 inches, isolated severe weather and flash flooding will remain a concern through the evening, mainly over southern and far eastern portions of the area, and HWO graphics will continue to reflect the risk areas. Overnight temperatures are expected to be in the upper 60s and lower 70s. Rain and thunderstorms are expected to start off Sunday morning as a shortwave disturbance moves off towards the east. A strong storm or two could be possible during Sunday morning but severe weather is not anticipated. As the shortwave progresses through the area, flash flooding threat should diminish as the afternoon progresses and rain chances will diminish late afternoon into the evening. /SW/ Sunday night through Friday night: Active westerlies will continue through the long term forecast bringing the potential for additional MCS activity and perhaps the threat for severe weather and localized flash flooding. Convective rainfall should be most prominent over northern portions of the area Mon-Tue, but it appears the Wed-Fri time frame will have the greatest concerns for the area as whole when a significant cold front is expected to push farther south toward the forecast area. /EC/ && .AVIATION... (00Z TAFS) Issued at 713 PM CDT Sat Jun 1 2024 TSRA will continue near KHEZ through around 02Z-03Z, but confidence in thunder impacts near the other TAF sites is too low to mention at this time. Chances for additional scattered SHRA or TSRA will increase after 15Z Sunday, especially for locations along and south of Interstate 20. Low stratus and possible patchy BR are expected to produce MVFR to IFR conditions between around 09Z to 15Z Sunday. /NF/ && .PRELIMINARY POINT TEMPS/POPS...
