NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 7, 2:22 PM CST, 1 hour 43 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS Issued by National Weather Service Huntsville AL 322 PM CDT Mon Jun 7 2021 .DISCUSSION... Tonight through Thursday A upper low continues to sit over Missouri and Arkansas. Breaks in the cloud cover this afternoon have allowed temperatures to climb into the lower to mid 80s. With humid airmass in place (dewpoints 70 to 75 degrees), SBCAPE between 3000 and 5000 J/KG can be seen over southern Mississippi per mesoanalysis. Models still hint at another weak shortwave pushing into the area during the mid-afternoon into the evening timeframe. Despite this shortwave pushing northeast through the area, shear with it will be very minimal. However, given abundant instability and dry air aloft forecast in soundings, damaging microbursts still look possible this afternoon and evening. Models do show some very weak helicity around 150 m2/s2 moving in with that weak shortwave. Cannot rule out a tornado totally, but that chance is very minimal. Given fairly slow movement of activity and higher PWATS, may have to watch out for ponding of water, minor localized flooding in some locations. With such a humid airmass in place, lows will likely only drop into the 70 to 75 degree range at best,especially with cloud cover a good portion of the night. This pattern dosn't change much Tuesday through Thursday, as the upper low and associated longwave trough axis very slowly creeps east. The main result will be scattered to sometimes more numerous showers and thunderstorms on and off during that period. This precipitation and associated cloud cover should help to keep temperatures in the 85 to 90 degree range primarily. If cloud cover is less than expected, highs may be a few degrees warmer in some locations on Thursday. Thursday through Sunday Chances of precipitation look like they will drop off Friday into the weekend, as the axis of the longwave trough shifts into the eastern Atlantic. Still will seeing some isolated to widely scattered showers or thunderstorms during this period, but should be drier and even warmer, as highs climb into the 90 to 95 degree range (heat index values may climb to around 100 degree by then as well). && .AVIATION... 18Z TAF discussion: TSRA coverage is the main concern thru 18Z/08; have attempted to break out VCTS, TEMPO, and prevailing TSRA according to confidence. GLH and GWO will have highest impacts and coverage thru this aftn, with PIB, HBG, and GTR a close second. JAN and HKS do not have immediate impacts at this time but should see coverage and impacts increase by 20Z. TSRA coverage should scale back somewhat after midnight but may continue to be a problem more than indicated in the TAFS. IFR ceilings will take the place of storms for most sites (MVFR at JAN and HKS). Ceilings should lift somewhat after daybreak, but TSRA coverage may increase near the very end of the TAF period. /BCC-HUN/ && .PRELIMINARY POINT TEMPS/POPS...
