NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 6, 2:37 PM CST, 2 hours 57 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 337 PM CDT Thu Jul 6 2023 ...New DISCUSSION... .DISCUSSION... Issued at 300 PM CDT Thu Jul 6 2023 Late this afternoon through Friday: An active, hot and humid, summer weather pattern continues in the near term. The circulation associated with an MCV dropping southeast into northern MS is helping to enhance moisture convergence/instability from the ArkLaMiss Delta region into north central MS, and a considerable amount of convective precip has developed as a result. Another upstream MCV in the ArkLaTex region will likely help to enhance convection for the rest of the day by promoting additional multicell storm development. The potential for microbursts will peak late this afternoon into the early evening in the very unstable (sfc- based CAPE ~4000 j/kg), and additional storms may develop as outflow approaches from the south. A marginal risk continues to be messaged for this threat. Storms will diminish later this evening with mostly quiet weather conditions overnight through early Friday morning. The environment should be similar to today as the air heats up Friday, but greater moisture convergence looks to focus over eastern portions of the area, and perturbed upper level flow could potentially help enhance multicell storm clusters once again. A few damaging microbursts certainly can't be ruled out for Friday afternoon/evening. /EC/ Friday night through late next week: An increasingly amplified upper pattern should increase deep layer shear amid a hot and humid airmass typical for this time of year, which will keep rain and storm chances throughout the long term forecast period. Given the lack of airmass change, mesoscale features will play a big role in how day-to-day events play out. Persistent northwest flow aloft will once again be favorable to steer disturbances from the southern plains into our area, and MCS intensity will likely have to be assessed each day. Unlike previous MCS events, midlevel lapse rates are not expected to be as steep within this pattern (6 c/km, 24-26 vertical totals) which may keep events from becoming as intense as observed previously. Even still, flow will be greater than usual for this time of year (25-35kts deep layer shear). At the surface, a stalled boundary early next week may serve as a focus for storms and could produce heavy rainfall amid increasing PWATs (2.2 -2.4 inches, which is about max when compared to sounding climatology). Rainfall totals could add up as storms train along the boundary and slow storm motions could increase flooding threat. This will likely have to be monitored in the coming days for a potential flood HWO. Current analysis by WPC highlights our area in a slight risk for excessive rainfall for early next week. Additionally, we are still dealing with the heat and humidity. There are no signs of this letting up as the pattern remains persistent. With dewpoints in the upper 70s to near 80, heat indices are likely to rise into the triple digits each day, especially for our western half. Given rain and storm chances, dangerous heat will be uncertain throughout the upcoming week and will have to be monitored each day. By late next week, rising heights and a northerly shift of the baroclinic zone could decrease rain and storm chances, especially for areas west of I-55, thereby increasing heat stress and heat HWO could be needed in future forecasts. /SAS/ && .AVIATION... (18Z TAFS) Issued at 105 PM CDT Thu Jul 6 2023 VFR conditions and light surface wind will prevail for the most part through this evening and into the overnight. Exceptions could be associated with brief TSRA encounters this aftn/evng. As we go into late night/early Fri morning, considerable MVFR/IFR category stratus may develop and impact sites for several hours. Low ceilings should quickly improve during the mid/late morning. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
