Mesoscale Discussion 0212 NWS Storm Prediction Center Norman OK 0356 PM CDT Sat Mar 15 2025 Areas affected...portions of middle into eastern Tennessee Concerning...Tornado Watch 47... Valid 152056Z - 152230Z The severe weather threat for Tornado Watch 47 continues. SUMMARY...The severe threat may continue downstream of Tornado Watch 47 into eastern TN. An additional WW issuance may be needed downstream pending favorable convective trends. DISCUSSION...A QLCS continues to progress across Middle TN, and is approaching the eastern bounds of Tornado Watch 47. Downstream, surface observations show surface temperatures exceeding 70 F amid upper 40s to low 50s dewpoints. Given 20+ F surface temperature/dewpoint spreads, a deeper, potentially drier boundary layer may be in place, which may augment damaging gust potential. Given large, clockwise curved hodographs (per regional VADs), QLCS tornado potential may also exist. As such, a downstream WW issuance may be needed if QLCS organization and intensity persists or especially increases. ..Squitieri/Gleason.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...
