NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 31, 9:25 AM CST, 3 hours 35 minutes earlier.
Area Forecast Discussion...Update National Weather Service Jackson MS 1025 AM CDT SUN JUL 31 2016 .UPDATE...The thunderstorm cluster (MCS) that moved into western portions of the region late yesterday evening (and then dissipated over the heart of our forecast area late last night) will continue to have a residual impact on our weather today. The MCV (remnant circulation) association with this cluster appears to now be moving east into Alabama, and subsidence in the wake of the feature will probably help stabilize many eastern portions of MS well into the afternoon. Elsewhere, a loose conglomeration of convection has been festering around the northwestern periphery of the region and there may be just enough instability and shear to evolve this into a thunderstorm cluster dropping south through central and western zones through the afternoon. However, confidence in that evolution is not high because influence of northern stream (and associated shear ingredient) is decreasing and should continue to do so gradually over the next 24 hours. But, regardless of that potential northern development, expect a residual boundary stretching latitudinally across southern zones to trigger 40 to 50 percent coverage of showers and storms there as we go into the afternoon. Right now we are thinking much less evening convection around today than was the case yesterday, once again owing to less influence from mentioned trough. Of course we will be monitoring closely for any changes in this somewhat chaotic convective environment. Fortunately, assessment of wet microburst potential off of area morning soundings reveals no enhanced risk for severe activity although there will certainly be enough instability to make it hard to rule out a stray strong to locally severe storm. /BB/ && .AVIATION...All TAF sites are VFR this morning and this will continue into the afternoon hours. Scattered SHRA/TSRA will develop after 18-19Z, and this will bring brief lowering of flight conditions to MVFR/IFR to affected sites. The thunderstorms will dissipate by 01-02z this evening. Patchy MVFR/IFR conditions will be possible once again early on Monday./15/ && .PREV DISCUSSION... /issued 333 AM CDT SUN JUL 31 2016/ SHORT TERM...Today through Monday night...Local radars are indicating the MCS, that moved into the area during the late evening, has just about devolved into a remnant MCV over central portions of MS this morning. Those that saw the rain have cooled into the lower 70s, while elsewhere mid to upper 70s were common. The mid/upper level ridge that has been persistent over the southern CONUS will begin building over the northern Gulf of Mexico this morning and drifting to the northwest tonight into Monday morning. Despite the proximity of the ridge and feeble lapse rates, scattered showers and thunderstorms still look like a good bet this afternoon as the airmass remains very moist (PWs ~ 2 inches). Northern areas should have the best chances for convection this afternoon as those areas remain exposed to the westerlies and have slightly better lapse rates that far away from the ridge. By Monday, the high center will have settled over the ArkLaTex region putting the CWA on the eastern periphery and into more of a mid level northerly flow regime. PWs remain around 2 inches and with weak shortwaves embedded in the flow, expect scattered afternoon convection to once again dot the landscape. With the moist airmass and warming daytime temperatures, heat indices in the lower 100s should be common today and near 105 by Monday. The one respite that we will have both today and Monday will be the afternoon convection. This may keep the high heat indices rather brief./26/ LONG TERM...Tuesday through Saturday...The presence of ridging aloft will subtly increase across the region throughout the course of the long term period. At the surface, high pressure will remain wedged into the forecast area front the east. This will result in weak southerly flow and a continued humid airmass over the CWA. Each afternoon, highs will warm into the middle 90s. This, combined with dew points in the low and middle 70s, will yield afternoon heat indices in the 100-107 range through a good portion of the period. This looks to especially be the case across the Delta, where the issuance of a Heat Advisory could be needed before all is said and done. Lows each night will fall into the middle 70s. Isolated to scattered showers and thunderstorms will be possible each afternoon. This convection will quickly dissipate around sunset each evening as daytime heating gradually wanes. /19/ AVIATION...MVFR visibilities in fog will give way to VFR conditions by 31/14Z. Scattered SHRA/TSRA developing after 31/18Z will mostly affect the vicinity of most TAF locations. However, those TAF sites that are impacted by TSRA will see brief lowerings of flight conditions to IFR. The convective potential will remain until 01/02Z./26/ && .PRELIMINARY POINT TEMPS/POPS...
