Area forecast discussion, Jul 20, 5:09 PM CDT, 3 hours 37 minutes before
Area Forecast Discussion National Weather Service Nashville TN 509 PM CDT Mon Jul 20 2020 .UPDATE... FOR 00Z AVIATION DISCUSSION. && .DISCUSSION... Scattered showers and storms are dotting the radar this afternoon. With 2500-3000 J/kg of MLCAPE a few storms may become strong for a short amount of time with 40-50 mph winds, frequent CG lightning, and heavy rain. Storms should die off as the evening wears on. Expect some patchy fog after midnight, especially in areas that are lucky enough to get some rain today. Storm coverage will increase tomorrow, but even more so on Wednesday as upper ridging weakens and impulses ride zonal flow north of the area. Right now, Thursday looks like it will have the most widespread storm coverage. A couple strong storms look possible each day through at least Thursday with gusty winds being the main threat each day. Upper ridging strengthens again this weekend and rain chances will become more isolated starting on Saturday. Model blends seem too aggressive with PoP numbers for this weekend, so PoPs were capped at 30% for both Saturday and Sunday. Temperatures for the forecast will continue to be hot. Wednesday and Thursday will be the "coolest" day thanks to wider-spread storms. It looks like a large part of the area will be back in the mid 90s by the weekend thanks to the upper ridge. West of the plateau, low temperatures will only drop into the low to mid 70s for the next seven days. && .AVIATION... 00Z TAF DISCUSSION. Late this afternoon, the upper high is shifting to the southeast and as a result, more convection is ongoing across southern KY and into northern portions of the mid state. This trend shall continue into Tuesday afternoon. At that time, convection coverage will likely increase even more as compared to today. Otw, could see some light areas of fog overnight tonight, especially where earlier rainfall occurred. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......Reagan AVIATION........21
