Area Forecast Discussion National Weather Service Nashville TN 938 AM CDT Tue Jun 29 2021 .UPDATE... FOR MORNING DISCUSSION. && .DISCUSSION... Hot and steamy again this morning. We're creeping up on 90 at BNA and it's not even 10 am. The big question is whether or not anyone will see relief from today's heat. I think the answer is no for most everyone, however the wild card is going to be the remnants of Danny. Currently centered over Central Alabama, radar is showing that some northward development is finally starting. Hi-res models haven't been handling this progression well so far this morning, but now that we're starting to see some of this convection in northern Alabama, I've tweaked PoPs to try and cover this trend over the next few hours, with scattered storms starting to spread into our southern counties over the next hour or so, and further northward progression into the early afternoon hours. Again, I don't expect everyone to see rain today, but definitely more lawns will see some rain than have in the last several days. Bigger story today will be the continued heat with Heat Indexes closing in on 100 in many spots, especially across our northern counties. Find some shade, take breaks and drink water out there! && .AVIATION... 12Z TAF DISCUSSION. VFR conditions continue. Expected VCTS mainly after 18Z, but difficult to pinpoint which terminals would be impacted if at all by TSRA. If a terminal does have a storm move over, expect a period of decreased vis. Light winds will remain throughout the TAF period. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......Unger AVIATION........Adcock
