Area Forecast Discussion National Weather Service Nashville TN 633 AM CDT Mon Jul 3 2017 .UPDATE... FOR 12Z AVIATION DISCUSSION. && .DISCUSSION... Same story has been shaping up every day for the past few days with chances for afternoon thunderstorms, and some being strong to severe. SPC has put in a marginal risk for severe storms mainly for western areas today thanks to approaching shortwave trough that has moved north over the past few model runs. It looks to mainly impact areas west of I-65 due to the location of the upper shortwave and assistance from diurnal help as progress of convection should only make it into western zones before sunset. Instability falls off quickly in the early evening, as well as deep layer shear which is pretty weak to begin with, so strong to severe threat should diminish this evening. Main threat will be damaging winds but also heavy rain, and with all of the precip over the mid state during the past week, flooding will be a concern especially in areas that received larger amounts over the last week. Upper shortwave stalls a bit over the mid state, so chances for showers and thunderstorms will linger into the overnight hours and morning on Tuesday. Model consensus is showing good agreement on this solution, so put in likely mention of showers and storms during this timeframe as the upper low moves through the mid state. Still holding out hope that the shortwave and associated precip chances move east and keep the evening timeframe around the Nashville metro area dry for holiday activities. Still carrying chance pops east of I-65 as some models have some lingering precip holding on to that area in the evening, but odds favor that most of the mid state will be dry after sunset. Wednesday will have some chances for showers and storms, but the better shot will be on Thursday. Another shortwave will develop and strengthen over northern MO, and has been pretty consistent within model runs. Good warm air/moisture advection ahead of the trough will increase precip chances during the day Thursday, and trough axis/cold front will continue chances Thursday evening into the early morning hours Friday. A brief dry period during the day Friday will be short lived as another trough over the Great Lakes moves eastward and brings more cold air southward, bringing chances for showers and storms back Friday night into the day Saturday. Sunday looks to be dry as northwest flow settles into the region. Kept the early part of next week dry as well since upper flow is weak, and no real shortwave activity to mention to kick off chances for precip. Right now, any storm activity would be diurnally driven, and long term models are not showing much around the area just yet. Models start to diverge quite a bit after this timeframe, so will enjoy the dry period should it pan out Sunday through Tuesday for now. && .AVIATION... 12Z TAF DISCUSSION. Patchy dense fog this morning will bring MVFR to VLIFR cigs/vis very early in the TAF period to CKV/MQY/CSV. Otherwise, MVFR/VFR cigs expected this TAF period with VCTS developing once again by 16-17Z at all airports. More widespread showers and storms anticipated Monday evening into Monday night as an upper level system moves across the area. Light south to west winds expected at all airports through the TAF period. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......Barnwell AVIATION........Shamburger
