Area forecast discussion, Jul 5, 3:49 PM EDT, 1 hour before
AREA FORECAST DISCUSSION National Weather Service Jackson KY 349 PM EDT Thu Jul 5 2018 .SHORT TERM...(This evening through Friday night) Issued at 349 PM EDT THU JUL 5 2018 The afternoon surface analysis shows a cold front and surface high pressure slowly pushing southward into the Upper Midwest, with weaker surface high pressure placed in the Eastern US. The convection has slowly started increasing this afternoon amid an unstable and moist environment. The best POPs so far this afternoon have generally been around Lake Cumberland and across the Bluegrass. These will be primarily mesoscale dominated processes through the afternoon and evening and therefore kept POPs in the slight to chance range through the period. The aforementioned cold front will slowly progress southward toward the region late tonight into Friday. This along with slight height falls will be the focus for convection for Friday and did generally keep the better POPs along and south of I-64. This is the area that stands to see the best potential for instability to build ahead of the lifting associated with the boundary. This boundary will slide southward and bring much drier airmass to round out the period, with PWATs dropping below 1 inch through the afternoon and evening hours Friday. .LONG TERM...(Saturday through Thursday) Issued at 349 PM EDT THU JUL 5 2018 High pressure will build south for the weekend allowing for dry and cooler conditions to be seen. The upper level ridge may break down a bit by Sunday afternoon allowing for a few showers or storms to develop in the Cumberland plateau into central Kentucky. The 12z GFS is looking much more active next week, at least with regards to afternoon convection. Thus, at least low end pops will be introduced into each period from Sunday through Thursday. A frontal boundary may drop in and stall over the region by mid week, allowing for better chances of organized convection. While temperatures will rebound back into the mid to upper 80s by Sunday, they should generally remain around that level through next week. This will keep the heat from becoming an issue again next week. && .AVIATION...(For the 12Z TAFS through 12Z Friday morning) ISSUED AT 741 AM EDT THU JUL 5 2018 Fog will bring sub-VFR conditions early this morning in many valleys and where significant rain occurred late Wednesday. Isolated showers and thunderstorms will also bring sub-VFR conditions to some locations this afternoon and tonight. Fog could also bring restrictions in valleys again late tonight. Otherwise, VFR conditions are forecast. Winds will be light (except near thunderstorms). && .JKL WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...DJ LONG TERM...KAS AVIATION...HAL
