Area Forecast Discussion National Weather Service Jackson MS Issued by National Weather Service Nashville TN 1218 PM CDT Thu Jun 27 2019 .UPDATE... Updated for 18Z aviation discussion && .AVIATION... 18Z TAF discussion: Scattered showers and thunderstorms will continue to move southward, potentially impacting GTR/GWO by 19Z and other terminals in the afternoon to early evening. If a thunderstorm passes directly over a terminal, MVFR conditions will be possible. Exact timing/location of these storms to each terminal is a bit uncertain, but these storms are slow moving. Showers/thunderstorms will move completely out of the area by 03Z with clearing from north to south. VFR conditions will remain into the morning hours. By 12Z tomorrow, another batch of showers could impact GLH. Light winds expected through the TAF period. && .DISCUSSION... Minor update to the forecast this morning to reflect current CAM guidance. Models still show the upper low over the mid MS River Valley heading southward slowly during the day today, which will provide some support for afternoon showers and thunderstorms. Strong MLCAPE will exist over the region however deep layer shear still looks very weak. Existing convection over western TN/northern MS will likely continue to develop on outflow from morning convection, and looks like that outflow will continue to help develop additional storms as it heads southward towards central MS. CAM consensus has some broken convection developing along the boundary in the early afternoon, and additional storms mid to late afternoon as well. Severe potential looks to be limited to damaging wind gusts with the stronger storms that may develop, but heavy rain will also be possible. Adjusted pops slightly to line up better with CAM consensus. Other than that, just minor tweaks to the forecast today and the rest of the forecast looks to be on track. Prior discussion below: Today and tonight: All is quiet over the ArkLaMiss this morning. A weak low has cutoff over the Mid-Mississippi Valley and will serve as the focal point for today's storm initialization. With storms already in progress in northern AR/TN this morning, this small complex will continue to shift southward through the day. The CAM guidance shows this system moving into northern MS later this morning and as it moves further away from the weak but better forcing, it will have a tendency to become disorganized. While there will be plenty of CAPE available in our area and good lapse rates to maintain the storms, model sounding profiles in north MS show weak shear. With shear so weak, the atmosphere will be hard pressed to maintain multi-cellular storms, but if this system can manage to stay somewhat organized moving into our CWA and maintain a decent cold pool then there will be the potential for some wet microbursts. Strong to damaging wind gusts and small hail will be the main threats. Again, expect high temps today to be right around normal - low 90s - for this time of year. Today's convection will dissipate with the sunset this evening and allow for the atmosphere to reset overnight. Similar to this morning, another small complex looks to develop early Friday morning where the cutoff low will continue meandering over the MidSouth. This could bring some early morning rain to our northern counties on Friday. /10/ Friday through next Wednesday night: Overall, a typical summer weather pattern is expected with a general weakness in the large scale subtropical ridge over the Lower MS Valley region. For Friday, the previously mentioned disturbance digging southward around the eastern periphery of the Southern Plains high center will help to enhance diurnal convective precipitation over the ArkLaMiss region. Colder air aloft (H500 T ~ -10C) will continue to support steep lapse rates favorable for more intense storms, however, timing of convective development will make for a complex/low confidence forecast as activity will likely develop early in the day, particularly over the Delta region, and this could disrupt potential during the more favorable afternoon hours depending on outflow influence. As we go into the weekend, an upper trough will shift westward and this should help to increase southerly low level flow while moderating temperatures aloft resulting in weaker lapse rates and slightly less severe microburst potential. It should be noted that the southerly flow could promote earlier convective development and fairly good coverage of showers/storms. Going into early next week, there are indications in the bulk of global model guidance that a ridge center will increase its influence over the forecast area resulting in slightly greater heat stress, so this will be a trend to monitor. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
