NWS Jackson, MS wrote its last area forecast discussion before the first event at May 12, 1:47 PM CST, 48 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 247 PM CDT Fri May 12 2023 ...New DISCUSSION... .DISCUSSION... Issued at 247 PM CDT Fri May 12 2023 Tonight & Saturday... Tonight: Expect convection to wind down into early evening. Persistent southerly return flow will keep high boundary layer moisture around for the overnight hours. Clouds will persist, with some lower stratus building in into the overnight hours. Some patchy fog is possible in central to southeast MS but especially into the Pine Belt just before daybreak. Can't rule out some fog being locally dense in the Pine Belt but confidence is too low to put in the HWO/graphics. Lows will be some 5-8 degrees above normal, in the mid 60s to the east to near 70 degrees in the ArkLaMiss Delta. Saturday: Expect low-level anticyclone to build to the west- northwest into Saturday, with increasing mid-level heights over the region. Some slightly drier air will build in, hovering around or just less than 1.5 inch PWs. With strong low-level WAA (i.e. low-level thermo in the mid teens-low 20s C at 925mb & 850mb, respectively) aftn highs will peak into the upper 80s-low 90s. Mid-level lapse rates & vertical totals/instability won't be as high as today (i.e. ~7 deg C @ 700-500mb & mid-upper 20s vertical totals) & combined with somewhat drier air & decreased low-level flow, aftn diurnal microburst potential will be less than today. However, a few strong storms & a rogue isolated severe storm or two can't be fully ruled out. Convection will wind down into early evening. In addition, heat stress will pick up, with heat indices climbing into the low-mid 90s. /DC/ Saturday Night through next Thursday... Ridging aloft will continue to strengthen across the region through the latter half of the weekend and into early next week. As this happens, high pressure at the surface centered east of the region will continue to supply plenty of moisture to the forecast area. The amplification of the ridge will result in highs through early next week peaking in the lower 90s areawide, with very humid conditions. This will also lead to an unstable airmass each afternoon with diurnally driven convection breaking out each day. Because of this overall setup in this moisture rich environment over the area, the potential for microbursts will need to be assessed on a daily basis as at least some potential will probably be possible each day. This will determine whether there's any potential for at least isolated strong to severe storms each afternoon. The ridge will begin breaking down across the region late Monday night into Tuesday as a trough approaches and swings through the region from the northwest Wednesday into Thursday. This is currently progged to push a cold front south into and through the forecast area mid-week, with some chance that the front could actually stall over some portion of the area during this time. This scenario will keep at least some chance for showers and storms in the forecast through the extended period. /19/ && .AVIATION... (18Z TAFS) Issued at 137 PM CDT Fri May 12 2023 Isolated to scattered TSRA/SHRA are ongoing, with some remnant decaying TSRA to the north bringing lowered vsby reductions at GLH & GWO to MVFR-IFR flight categories. All sites will have some potential for impacts/reductions to MVFR-IFR through the aftn, with eastern sites a little later. Brief gusts up to 40kts are psbl in any stronger convection. TSRA/SHRA will clear after 13/00-02Z. Surface wind will be mostly light, generally less than 10mph, from the south. Expect potential MVFR-IFR flight category stratus/cigs, with potential lower vsby, after 13/08-09Z through mid-morning Sat. More isolated-scattered TSRA/SHRA are expected into Sat aftn. /DC/ && .PRELIMINARY POINT TEMPS/POPS...
