Area forecast discussion, Jul 8, 4:01 PM EDT, 2 hours 46 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 401 PM EDT Wed Jul 8 2020 .SHORT TERM /Tonight through Thursday Night/... Expect largely diurnal convection to continue through the short term as deep moisture remains over the region. Lingering surface boundary from exiting low will provide a focus for convection tonight. With high precipitable water values, expect stronger storms to be efficient rain producers. For Thursday, weak northwest flow will guide two upper level impluses into the area, promoting afternoon and evening convection. Models are in good agreement with showing better initiation over the southern CWA and the northeast Georgia mountains, so have gone ahead and included likely pops for those areas for Thursday afternoon. Pops diminish into the late evening hours. Near normal to slightly below normal temperatures are expected through the period. 31 .LONG TERM /Friday through Wednesday/... A strong upper level high pressure system over the SW United States will continue to steer low pressure systems from out of the great lakes through the SE. This nearly continuous upper level trough will keep pops at chance through the rest of the forecast period. This NW flow shows the potential to trigger an MCS somewhere in the SE by the end of the weekend. Severe parameters are showing the potential for a favorable severe weather environment with a 200mb jet and steep mid-level lapse rates, especially across northern Georgia. Temperatures will climb in to the lower 90s by Friday across northern Georgia and upper 90s across south and central Georgia. Dewpoints will range from the mid to lower 70s for most of the CWA. This combination of heat and humidity will push heat indices over 100 for SE portions of the CWA Friday through Sunday. These temperatures will continue through the forecast period, hovering slightly above climatological average. Vaughn && .AVIATION... 18Z Update... Convection is ongoing/continuing over the western portions of the state. SCT MVFR with BKN/OVC VFR cigs are present, and some improvement is expected as storms die off this evening. Lower storm chances are expected at KMCN and KAHN, otherwise main timing for TAF sites is 20 to 00z. Winds have generally shifted to the west side at 4-8kt, and expect them to stay west through the period. Higher speeds are possible near/in convection. Lowering ceilings are expected overnight, with BKN IFR by 08-11z. Improvement expected after 14z. Storms possible again after 18z Thursday. //ATL Confidence...18Z Update... Medium to high confidence on all elements. 31 && .PRELIMINARY POINT TEMPS/POPS...
