Area Forecast Discussion National Weather Service Nashville TN 558 AM CDT Sun Jun 10 2018 .UPDATE... FOR 12Z AVIATION DISCUSSION. && .DISCUSSION... It had been quiet since midnight, but showers and a few rumbles of thunder have started to develop around forecast time. Fairly evident as to why and where they are developing; mesoanalysis would suggest the best instability is west of I-65, coupled with the weak shortwave pushing out of southern MO, which can be seen in the GOES- 16 water vapor imagery, we're getting the necessary lift to spark the convection. I think we can expect this type of development for the rest of the early morning hours and possibly even some expanded coverage as outflows starts to roam Middle TN. With CAPE values only about 1000 J/Kg, we could get one strong storm, and with the slow movement of these storms, localized flooding could become an issue, but even that is a small chance. Either way, this might put a damper on the morning hours for any outdoor activities, but with the morning convection, it should stymie any afternoon/evening development. The downside is, if we don't get the afternoon convection, temperatures are expected to climb into the upper 80s to around 90 and with dew points in the upper 60s to 70, Heat Index values will likely be in the mid-90s and the air will be swampy. If you have outdoor plans, please be aware of the potential for easy-onset heat related illnesses. Drink plenty of water and get some shade when you can. Models are really all over the place regarding this entire week's forecast. I think it has to do with the quasi-northwesterly flow over the region. They notoriously don't handle this type of pattern well. I say quasi because we're not in a strong NW flow. We're kind of on the downstream end of the flow, which means subsidence isn't real strong, but steering currents for potential upstream MCSs to reach us are weak. So, I think we have to go with a very summertime like PoP-pattern for this whole forecast. Afternoon and evening convection, some of the storms could be strong, and without a strong upper ridge, afternoon highs can be expected around 90 (mid 80s on the Plateau). Depending on the timing of afternoon convection, some may only get to 84-88 on any given day. This forecast will be brought to you by the 12Z/Sat and 00Z/Sun Euro and because of this, I'm going to raise temperatures a couple of degrees and decrease PoPs in the extended as the depiction of strong upper level ridge is becoming apparent by next weekend. Shy of that, nothing more than chance PoPs each afternoon this week. && .AVIATION... 12Z TAF DISCUSSION. BNA/MQY/CKV/CSV...A shortwave is coming through Middle Tennessee at this time, with the current band of convection you see on radar occurring right along the upper trough. These showers and storms are moving quite slowly and will take several more hours to exit the mid state. This represents most of what we'll see today, with the HRRR only depicting isolated, light showers during the afternoon, and the latest MAV guidance lowering POP's considerably after 18Z. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......Unger AVIATION........08
