NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 29, 2:41 PM CST, 41 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 341 PM CDT Wed Aug 29 2018 .DISCUSSION... Current afternoon storm activity is working out mostly as expected, the exception being the better coverage across the NW areas. Look for activity to slowly evolve through 5pm with a downward trend between 6-8pm. There remains some potential for strong storms and possibly a few reaching severe limits. Updrafts have been a bit more robust than yesterday, but they are still falling short. The evening will be quiet with persistence being the rule for low temps. For Thu, model consensus has trended to lesser in the way of PoPs and I have followed that suggestion. There will still be activity and no area can be ruled out, but better chances look to be across the N/NE/E parts of the forecast area. Like today, some strong storms will be possible with gusty winds being the main threat. Temps aloft will again be on the cooler side, but not as cool as today which supports the expectation of strong storms. As for temps, like with lows, a persistence approach is best and highs will mainly range from 90-93. /CME/ Thursday night through next Tuesday: Warm and humid conditions will continue across the area through the period, as high pressure off the east coast will result in east to southeast flow. High temperatures will range from the upper 80s to mid 90s, with overnight lows mainly in the 70s. The humidity should remain low enough to keep heat index values below 105 degrees. As for precipitation, decent chances for afternoon and evening showers and thunderstorms will persist through the period. This activity looks to dissipate during the evening hours, with quiet weather expected during the overnight hours. /27/ && .AVIATION... 18Z TAF discussion: Main focus for these TAFs are timing in/out the showers and storms. Look for a decreasing trend during the back part of the afternoon hours and a quiet overnight. I did not add any restrictions for sites, but there is some low end potential for some MVFR conditions at PIB/HBG/MEI between 11-13z. Later forecasts can refine that. /CME/ && .PRELIMINARY POINT TEMPS/POPS...
