WW 606 SEVERE TSTM AL KY MS TN VA 052145Z - 060500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 606 NWS Storm Prediction Center Norman OK 445 PM CDT Fri Sep 5 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far Northwest Alabama Central and Eastern Kentucky Far Northeast Mississippi Western and Middle Tennessee Extreme Western Virginia * Effective this Friday afternoon from 445 PM until Midnight CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorm coverage is expected to increase along and ahead of a cold front progressing slowly southeastward through the region. Environmental conditions will support a few supercells capable of large hail and damaging gusts. Some clustering is possible over time, with damaging gusts possible within these storm clusters as well. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 55 miles northwest of Muscle Shoals AL to 25 miles east southeast of Jackson KY. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26025. ...Mosier Read more

MD 2040 CONCERNING SEVERE THUNDERSTORM WATCH 606... FOR TN/KY
Mesoscale Discussion 2040 NWS Storm Prediction Center Norman OK 0820 PM CDT Fri Sep 05 2025 Areas affected...TN/KY Concerning...Severe Thunderstorm Watch 606... Valid 060120Z - 060245Z The severe weather threat for Severe Thunderstorm Watch 606 continues. SUMMARY...A diminishing severe threat is anticipated through late evening, mainly across parts of Tennessee and Kentucky. Additional Severe Thunderstorm Watch issuance is not expected. DISCUSSION...An earlier cluster over southern Middle TN weakened substantially, with the near-term severe threat largely focused across northern Middle into northeast TN with a short cluster. Redeveloping convection to the west along the cold front will likely struggle to intensify given that the decayed remnants of the earlier cluster having pushed outflow into far north AL. This is similarly underway across KY where earlier convection across eastern KY into WV has diminished and stabilized the environment somewhat ahead of separate convection trailing along the cold front. ..Grams.. 09/06/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 2039 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF FAR NORTHEAST TEXAS INTO EXTREME SOUTHEAST OKLAHOMA
Mesoscale Discussion 2039 NWS Storm Prediction Center Norman OK 0805 PM CDT Fri Sep 05 2025 Areas affected...portions of far northeast Texas into extreme southeast Oklahoma Concerning...Severe potential...Watch unlikely Valid 060105Z - 060200Z Probability of Watch Issuance...20 percent SUMMARY...A few severe gusts could still occur over the next few hours. DISCUSSION...A multicellular cluster has produced at least one pronounced downburst, with wind damage noted, along with 1+ inch diameter hail. This complex continues to track north of a zonal frontal boundary, where 2000-3000 J/kg MLCAPE resides downstream. 30-40 kts of effective bulk shear and the aforementioned buoyancy would continue to support severe gusts. However, MLCINH should also increase with time. The current thinking is that the severe threat should remain confined to the ongoing complex, where a few strong to severe gusts may still occur. ..Squitieri/Mosier.. 09/06/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 2038 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHERN TEXAS
Mesoscale Discussion 2038 NWS Storm Prediction Center Norman OK 0622 PM CDT Fri Sep 05 2025 Areas affected...portions of northern Texas Concerning...Severe potential...Watch unlikely Valid 052322Z - 060115Z Probability of Watch Issuance...20 percent SUMMARY...At least a few instances of severe wind or hail may accompany the stronger storms this evening, particularly with any supercells that can become established. DISCUSSION...Thunderstorms are intensifying near a surface frontal boundary draped zonally across northern TX (just north of the Metroplex). Ahead of these storms resides a buoyant airmass, characterized by steep mid-level lapse rates over a mixed boundary layer with 15-20 F temperature/dewpoint spreads. Furthermore, general veering with height is contributing to elongated and curved hodographs (albeit with some veer-back-veering within the profiles per RAP forecast soundings). With 40 kt effective bulk shear values overlapping with 1500-2500 J/kg MLCAPE ahead of ongoing storms, multicells and supercells are possible, accompanied by both a severe wind/hail risk. The ongoing storm over Denton County is currently exhibiting outflow tendencies per KFWS NEXRAD radar imagery, which will likely help drive the frontal boundary southward. As such, it is unclear how many storms will be able to cross to the warm side of the boundary. Overall, the complex mesoscale setup and undercutting boundaries suggest that the overall severe threat may remain isolated. ..Squitieri/Mosier.. 09/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 2037 CONCERNING SEVERE THUNDERSTORM WATCH 606... FOR MIDDLE TN AND FAR NORTH AL
Mesoscale Discussion 2037 NWS Storm Prediction Center Norman OK 0559 PM CDT Fri Sep 05 2025 Areas affected...Middle TN and far north AL Concerning...Severe Thunderstorm Watch 606... Valid 052259Z - 060100Z The severe weather threat for Severe Thunderstorm Watch 606 continues. SUMMARY...A more concentrated swath of strong to localized severe gusts is possible with potential for a slow-moving cluster to accelerate across mainly southern Middle Tennessee through mid-evening. DISCUSSION...The deepest convective cores have persisted over the past couple hours across southwest TN. These have congealed into an initially slow-moving cluster into southern Middle TN with forward motion of only 15-20 kts. But with strengthening of the surface temperature gradient, from upper 60s in the emerging cold pool to 85-90 F persisting ahead of the outflow, a more concentrated swath of strong to localized severe gusts may evolve over the next 2-3 hours. This would be coincident with probable acceleration of the cold pool that yields more moderate westerly storm motions into mid-evening. This might eventually approach the southeastern edge of WW 606 and necessitate a local areal extension. Weak low-level west-southwesterlies evident in area VWP data does lower confidence on just how robust the damaging wind threat may become. ..Grams/Mosier.. 09/05/2025 ...Please see www.spc.noaa.gov for graphic product...

Scattered damaging winds, isolated severe hail, and a brief tornado or two remains possible across the Upper Ohio/Tennessee Valleys this evening. ...OH/TN Valley Region... Latest satellite and radar imagery suggest a low-amplitude short-wave trough extends across eastern IL into northwestern TN. Longer radar loops depict the remnants of a long-lived MCV advancing ahead of this feature across central IN. The southern influence of the short wave/MCV appears to be encouraging scattered robust convection along a frontal zone draped across eastern KY into middle TN. Locally damaging winds have been noted with some of this activity and wind should remain the primary concern, though marginally severe hail is also possible, along with some risk for a brief tornado or two. While deep-layer shear is not particularly impressive, adequate flow persists along the frontal zone such that a severe risk will continue through much of the evening. Farther southwest along the front into north central TX, isolated severe thunderstorm has developed along the wind shift, just north of Dallas. Large hail is likely occurring with this storm that has supercell characteristics at times. 00z sounding from FWD exhibited very steep lapse rates through 5km, and 0-6km bulk shear was on the order of 40kt. Given the steep lapse rate environment, some risk for hail/wind will continue with any storms along the trailing boundary into this portion of the southern Plains. ..Darrow.. 09/06/2025 Read more
