MD 2105 CONCERNING SEVERE THUNDERSTORM WATCH 681... FOR EASTERN KY/TN INTO SOUTHWEST WV/WESTERN VA
Mesoscale Discussion 2105 NWS Storm Prediction Center Norman OK 0552 PM CDT Tue Sep 24 2024 Areas affected...Eastern KY/TN into southwest WV/western VA Concerning...Severe Thunderstorm Watch 681... Valid 242252Z - 250045Z The severe weather threat for Severe Thunderstorm Watch 681 continues. SUMMARY...Some hail/wind threat continues with scattered storms this evening. DISCUSSION...Short-wave trough is ejecting across the OH Valley early this evening and scattered strong/severe convection continues within the warm-advection zone, well ahead of the front. Over the last few hours, greatest concentration of robust, long-lived updrafts/supercells is beneath the strongest mid-level flow across eastern KY/northeast TN. Radar data suggests at least 4-6 supercells, extending 50mi either side of the TN/KY border, moving east-northeast toward western VA/southwest WV. However, air mass is notably less buoyant downstream and these updrafts will encounter increasingly hostile environment across the higher terrain and points east. Until then, hail/wind threat will continue with these storms. ..Darrow.. 09/24/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RNK...RLX...MRX...JKL...LMK...OHX...

MD 2104 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL OKLAHOMA
Mesoscale Discussion 2104 NWS Storm Prediction Center Norman OK 0355 PM CDT Tue Sep 24 2024 Areas affected...central Oklahoma Concerning...Severe potential...Watch possible Valid 242055Z - 242300Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorms are expected to develop along a cold front across west-central OK late this afternoon into this evening. Strong mid-level flow, adequate surface moisture and buoyancy will support a risk for severe hail and isolated damaging winds. Confidence in the convective evolution is somewhat low, but the severe risk may require a weather watch. DISCUSSION...Afternoon WV imagery showed a large upper trough over the central US. Behind the large trough, an embedded shortwave perturbation was moving out of the central Rockies and over the southern Plains. beneath the mid-level ascent ahead of the shortwave trough, a weak surface low and cold front were moving into western OK. Visible imagery and SPC mesoanalysis show towering cumulus has begun deepening near the triple point and along the trailing front into the TX Panhandle. Low to mid 60s F surface dewpoints and 7-7.5 C/km mid-level lapse rates were supporting weak to moderate destabilization despite lingering cirrostratus across OK. Further heating and weak low-level warm advection ahead of the surface low should support continued destabilization and removal of remaining inhibition through the afternoon. Scattered thunderstorm development is expected along the cold front, and more elevated development near/north of the warm front with storms moving east/southeast towards central OK. Increasingly strong mid and upper-level flow from the KTLX/KVNX VADs are supporting long hodographs favorable for supercells. While lapse rates and buoyancy are not overly impressive, modestly cool mid-level temps, robust forcing and strong deep-layer shear suggest any supercells that develop will be capable of severe hail and isolated damaging gusts. Confidence in the exact timing of storm development and the convective evolution remains unclear. Most hi-res guidance favors near-surface based storms developing late this afternoon, with some solutions holding off until early evening. While uncertain, the environment is expected to support a risk for severe hail, and a watch may be needed. ..Lyons/Guyer.. 09/24/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 682 SEVERE TSTM OK 242245Z - 250400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 682 NWS Storm Prediction Center Norman OK 545 PM CDT Tue Sep 24 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central Oklahoma * Effective this Tuesday afternoon and evening from 545 PM until 1100 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Widely scattered thunderstorms will intensify early this evening across central Oklahoma and drift eastward across the watch area. Initial storms will pose a risk of large hail, with an increasing threat of gusty/damaging winds later this evening. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 35 miles northwest of Chickasha OK to 15 miles east northeast of Mcalester OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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. && OTHER WATCH INFORMATION...CONTINUE...WW 681... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 28030. ...Hart Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0443 PM CDT Tue Sep 24 2024 Valid 261200Z - 021200Z A closed upper-low will develop and become cut-off and remain across portions of the Mississippi Valley through much of the extended period. During this period, Hurricane Helene will also be absorbed into the broader upper flow and bring an anomalously moist airmass into the region. The combination of cool and moist conditions associated with this upper pattern will alleviate most fire weather concerns across the eastern CONUS through the extended period. Ridging will result in warm and dry conditions across much of the western CONUS during the period. While critically dry fuels are mostly sparse across the western CONUS presently, this extended warm/dry period may result in larger regions of critically dry fuels (particularly fine fuels) by the end of the weekend when the next trough crosses the western CONUS. At this time the forecast winds/relative humidity are not strong/dry enough to warrant any Critical probabilities, especially given the questionable/sparse dry fuels presently. ..Bentley.. 09/24/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
