Area Forecast Discussion National Weather Service Nashville TN 612 AM CDT Sun Sep 22 2019 .UPDATE... FOR 12Z AVIATION DISCUSSION. && .DISCUSSION... Persistent upper ridging and Bermuda high hang on again today ...but finally break down tonight. By 12z Mon, weak upper shortwave is approaching and a cold front is expected to be set up just to our northwest. As this weak upper axis moves east, the cold front will sweep across the mid-state on Mon. GFS remains with best moisture advection ahead of the boundary, with the EURO still fairly dry. And instability remains very much lacking as well. Overall, expect showers to breakout toward dawn Mon across the northwest, then spread across the remainder of the area throughout the day. Pcpn amounts again will be pretty small. At this point, will only put small chance of afternoon storms as if any develop they will be isolated at best. Even though upper flow fairly benign, pretty good SFC/LL high builds in and pushes boundary well south, where it stays into early Wed. SFC high quickly vacates later Wed and the boundary retreats north late Wed and sets up just northwest early Thu ahead of next upper wave. With upper flow turning more northerly with time, this boundary expect to continue north on Fri. During this process, we may be able to squeeze out a few showers late Wed into Thu but again no significant pcpn is expected. After that point...upper ridges and SFC/LL highs strengthen once again, and hold into early next week. That will again make rain very scarce while keeping temps well above normal. On a side note...dewpoints are likely to drop into the mid 50s later today, and with winds speeds picking up and pretty dry ground conditions, marginal fire danger is likely this afternoon. Will highlight just in FWF for now. && .AVIATION... 12Z TAF DISCUSSION. No changes needed to the current TAF forecast. VFR conditions through the TAF period. High pressure over GA/SC will continue to get pushed east as a weak front heads to the mid Ohio Valley and into middle TN after 12Z Monday. Southerly winds today with afternoon and early evening gusts of 10 to 15kts. Winds will relax after sunset. A few high clouds during the afternoon and will become more scattered overnight. The leading edge of the front and rain will be approaching CKV by 12Z Monday. Rain amounts with the front will be light and CIGS and VIS will remain VFR. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......07 AVIATION........12
