Area Forecast Discussion National Weather Service Jackson MS 1230 PM CDT Thu Aug 6 2026 ...New AVIATION... .KEY MESSAGES... - Heat stress increases into the weekend and persists into mid next week. && .DISCUSSION... Issued at 201 AM CDT Thu Aug 6 2026 Through mid next week (Wednesday)... Today (Thursday) and Friday: RAP/water vapor analysis indicates stagnant upper pattern: remnant upper low losing influence/washing out over the Southeast states this morning and 596-597DM mean ridge aloft over the Desert Southwest. Heights are building with light and variable low level flow gradually shifting southerly through Friday. This locks in PWs generally around one inch (1.2 inches) and low humidity aloft (i.e. 700-300mb layer humidity in mid teens to low 20 percent range) in east to northeast MS while deeper moisture (1.6 to 1.8 inches) over central to southern MS and portions of northeast LA. Deep moisture will spread areawide into Friday. Increased warm advection (WAA) will moderate temperatures: highs becoming seasonably warm into Wednesday (95F to 97F) and seasonable lows (70F to 75F this morning and again tonight). Heat indices will continue to increase today in central to southwestern areas (heat indices in the 102F to 107F range this afternoon) and areas along and west of Interstate 55 Friday. Inherited HWO graphics for Limited and Elevated heat in southwest today seems reasonable. With moist advection picking up and lapse rates in northeast LA to south central to southwest MS and northeast LA, some diurnally induced showers and isolated storms may develop. This weekend through mid next week (Saturday through next Wednesday): Synoptic pattern will shift to deepening mean ridge over the Four Corners while the southeast states caught in between ridge to the west and subtropical ridge off the Atlantic seaboard. Surface boundary layer moisture will increase/higher surface dewpoints this weekend (72F to 77F). Combined with seasonable warmth (highs 93F to 96F), heat stress will only spread and increase in area, continuing into early next week. HWO graphic looks good for the weekend and continued the threat into early next week (Tuesday). Further refinements and heat headlines will likely be needed. Low level moist advection and increased deep moisture aloft will increase this the weekend (PWs in the 1.7 to 2.1 inch range late weekend into next week). Rain chances will mainly be summertime variety (diurnally induced) Thursday south of Interstate 20 and along and southeast of Natchez Trace into the weekend and spreading northwest into early next week. Coverage will be isolated to at times scattered coverage (20 to 40 percent range) with highest coverage in the Pine Belt, with potential sea breeze influence. This pattern does not favor noteworthy organized storm threat, but scattered stronger gusty storms with locally heavy rain cannot be ruled out, especially late weekend through mid next week. /DC/ && .AVIATION... (18Z TAFS) Issued at 1228 PM CDT Thu Aug 6 2026 VFR conditions prevail. Scattered to broken mid to high clouds will largely stay south of the I-20 corridor. There is a low chance (<30%) for a shower or thunderstorm this afternoon at southern cites, but all activity diminishes after sunset. /SAS/ && .PRELIMINARY POINT TEMPS/POPS...
