WW 47 TORNADO TN 151750Z - 160200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 47 NWS Storm Prediction Center Norman OK 1250 PM CDT Sat Mar 15 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Middle Tennessee * Effective this Saturday afternoon and evening from 1250 PM until 900 PM CDT. * Primary threats include... Several tornadoes and a couple intense tornadoes likely Widespread damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...A line of thunderstorms will spread east-northeastward across middle Tennessee this afternoon and evening. Widespread damaging winds up to 60-75 mph are expected along with several tornadoes as the environment becomes increasingly favorable for severe thunderstorms. A couple strong to intense tornadoes also appear posssible with any embedded supercells.

MD 0214 CONCERNING TORNADO WATCH 47...48... FOR NORTHERN ALABAMA INTO EASTERN TENNESSEE
Mesoscale Discussion 0214 NWS Storm Prediction Center Norman OK 0621 PM CDT Sat Mar 15 2025 Areas affected...Northern Alabama into eastern Tennessee Concerning...Tornado Watch 47...48... Valid 152321Z - 160115Z The severe weather threat for Tornado Watch 47, 48 continues. SUMMARY...The threat for tornadoes and severe gusts continues across northern Alabama into eastern Tennessee for the next few hours. DISCUSSION...Over the past 1-2 hours, convection across north-central AL has struggled to maintain intensity as it migrates into a deeply saturated, rain cooled environment. Recent surface observations depict a rather pronounced surface warm front extending across northern AL that delineates the northern extent of appreciable surface-based buoyancy. Despite the thermodynamic challenges, the low to mid-level theta-e axis remains in place across north-central AL. Strong isentropic ascent within this regime continues to support very strongly veered hodographs within the lowest few kilometers, exemplified by KBMX and KHTX VWP observations featuring 0-1 km SRH on the order of 400-500 m2/s2. Additionally, GOES IR imagery and lightning data have shown occasional updraft pulses within this warm advection regime and embedded supercell structures within a broken line of storms across eastern Middle TN which hint that buoyancy remains adequate for at least transient deep convection. Recent WoFS guidance appears to support this idea with some signal for low-level helicity tracks and severe gust potential focused across northeast AL into eastern/southeastern TN between 23-02 UTC. ..Moore.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0213 CONCERNING TORNADO WATCH 46... FOR SOUTHERN MISSISSIPPI INTO CENTRAL AND SOUTHERN ALABAMA
Mesoscale Discussion 0213 NWS Storm Prediction Center Norman OK 0618 PM CDT Sat Mar 15 2025 Areas affected...southern Mississippi into central and southern Alabama Concerning...Tornado Watch 46... Valid 152318Z - 160215Z The severe weather threat for Tornado Watch 46 continues. SUMMARY...The environment remains quite favorable for strong tornadoes, but will depend on storm mode going into the evening and early morning hours. DISCUSSION...Supercells moving out of eastern MS have transitioned into more of a small MCS this evening, from west-central AL into parts of eastern MS. Farther south, more discrete cell mode was noted across far southern MS to the LA border. While storm mode is currently a bit disorganized, shear, moisture and instability all remain favorable for conditionally strong tornadoes at any point this evening and through early morning. In addition, dewpoints and thus instability will also increase across the remainder of eastern AL and toward GA late tonight as the low-level jet persists. It is possible that reorganization may take place later this evening as we transition out of the daytime/diurnal regime. Any robust, discrete cells will have a high conditional risk of being tornadic supercells. Any linear structures may still produce tornadoes and swaths of damaging wind as well as effective SRH remains at or above 500 m2/s2. ..Jewell.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0212 CONCERNING TORNADO WATCH 47... FOR PORTIONS OF MIDDLE INTO EASTERN TENNESSEE
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...

MD 0210 CONCERNING TORNADO WATCH 45...46... FOR SOUTHEAST MISSISSIPPI INTO CENTRAL ALABAMA
Mesoscale Discussion 0210 NWS Storm Prediction Center Norman OK 0329 PM CDT Sat Mar 15 2025 Areas affected...southeast Mississippi into central Alabama Concerning...Tornado Watch 45...46... Valid 152029Z - 152230Z The severe weather threat for Tornado Watch 45, 46 continues. SUMMARY...Multiple supercells capable of intense to potentially violent tornadoes to persist into the evening. DISCUSSION...A line of supercells continues from east-central Alabama to south-central Mississippi. Most of these supercells have a history of tornadoes including a few intense to potentially violent tornadoes. The environment ahead of these supercells remains very favorable for tornadoes with 1500 to 2000 J/kg MLCAPE per SPC mesoanalysis and 0-1km SRH in excess of 300 m2/s2 per GWX VWP. This yields a STP value around 5 which is forecast to shift east with these storms through the evening. Convective trends have shown rapid strong to intense tornado development in supercells with unimpeded inflow and circulation disruption when surrounding showers/thunderstorms impede this inflow. Expect this pattern to continue into the early evening with the greatest concern being supercells with clear inflow of at least mid 60s dewpoints. The threat for intense to potentially violent tornadoes will persist from these supercells as long as they can remain ahead of the developing line of storms across central Mississippi. Based on current storm motions, they should remain ahead of this line of storms into the early evening. ..Bentley.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0211 CONCERNING TORNADO WATCH 45...46... FOR GULF COASTAL AREAS OF MISSISSIPPI...ALABAMA...AND THE WESTERN FLORIDA PANHANDLE
Mesoscale Discussion 0211 NWS Storm Prediction Center Norman OK 0340 PM CDT Sat Mar 15 2025 Areas affected...Gulf coastal areas of Mississippi...Alabama...and the western Florida Panhandle Concerning...Tornado Watch 45...46... Valid 152040Z - 152215Z The severe weather threat for Tornado Watch 45, 46 continues. SUMMARY...The severe threat, including a few tornadoes, may develop along portions of the Gulf Coast if storms can continue developing along the shoreline. Tornado Watch expansions may be needed over the next few hours. DISCUSSION...Multiple supercells have developed along the LA/MS border and continue to track northeast with a tornado threat. However, storms continue to develop southward near Lake Pontchartrain, and as deep-layer ascent continues to increase over the Gulf Coast region, additional storms may develop along the shoreline. The MOB VAD has shown a slight but steady increase in hodograph size and curvature through the afternoon, with 0-3 km SRH approaching 600 m2/s2. Given rich Gulf moisture and associated buoyancy, the potential exists for tornadoes and damaging gusts if a sustained supercell structure can materialize. Should this scenario become apparent, ongoing Tornado Watches 45-46 may need to be expanded to the Gulf Coast. ..Squitieri.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product...
