Area Forecast Discussion National Weather Service Paducah KY 726 AM CDT FRI AUG 26 2016 .UPDATE... Issued at 726 AM CDT FRI AUG 26 2016 Updated aviation discussion. && .SHORT TERM...(Today through Sunday) Issued at 329 AM CDT Fri Aug 26 2016 A southeastern CONUS high will continue to have a suppressing effect on shower and tstm activity in our region, i.e., limiting the coverage and strength of it in the short term. That said, a weak cold front will be in the area today before washing out, offering some source of lift. At the same time, a surge of deeper moisture from the Gulf region is shown by the models to kick in early today on the western fringe of the PAH forecast area ahead of northern stream mid level shortwave energy. Through Saturday, moisture aloft will continue to flow to the northeast over a retreating dome of higher surface pressures. Today, this should result in the development of scattered showers and tstms, primarily in the western counties, by early afternoon when the convective temp is reached. By Early Saturday, with a more southerly low level fetch, and better mid level winds, shower and tstm activity is expected to be more numerous, especially in southern IL and adjacent parts of southeastern MO and southwestern IN. As the shortwave energy departs Saturday evening, the partially diurnal convection should diminish quickly. The latter half of the weekend will have fewer clouds and a limited chance of something lighting up mainly in the Evansville Tri-State region. Temps should make it to around 90 today, and Saturday in most areas, with a slight uptick Sunday with more insolation. Afternoon heat indices of around 100 can be expected through the weekend, mainly in southern and eastern counties. .LONG TERM...(Sunday night through Thursday) Issued at 329 AM CDT Fri Aug 26 2016 Below average confidence in the long term due to model discrepancies. The long term forecast will continue to be dependent on the strength and position of a dirty H5 ridge that fluctuates back and forth across our CWA through most of the period. As a result, precipitation chances will be rather small and be more diurnal in nature through Wednesday with coverage mainly dependent on the location of small scale/mesoscale focusing mechanisms such as outflow boundaries. Starting Wednesday night the ridge is suppressed to the south a bit allowing for better flow aloft and the approach of a back door cold front. The front is forecast to drop southward into our CWA on Thursday which will increase precipitation chances through the end of the period. Models not in good agreement on the position and strength of the ridge so forecast will likely have to be adjusted with time. Temperatures will remain normal to slightly above normal through the long term period. && .AVIATION... Issued at 726 AM CDT Fri Aug 26 2016 High clouds will be quite plentiful today across the region. Expect a light easterly to southeasterly wind through the 24 hr TAF period, and still a possibility of MVFR vsbys toward sunrise Saturday due to fog. Afternoon thunderstorm activity, especially that which would result in vsby or cig restrictions, was deemed not likely enough to include in the TAFs at this time. && .PAH Watches/Warnings/Advisories... IL...None. MO...None. IN...None. KY...None. && SHORT TERM...DB LONG TERM...JP AVIATION...DB
