SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1159 PM CST Sat Dec 09 2023 Valid 101200Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF FAR EASTERN SOUTH CAROLINA AND EASTERN NORTH CAROLINA... ...SUMMARY... Severe thunderstorms associated with wind damage and a few tornadoes are expected across parts of far eastern South Carolina and eastern North Carolina today. Marginally severe wind gusts will also be possible over much of the Atlantic Coastal region from Florida to the Mid-Atlantic. ...Atlantic Coastal States... An upper-level trough will move eastward across the Ohio and Tennessee Valleys today, as an associated belt of strong mid-level flow translates eastward into the Appalachians and Atlantic coastal states. At the surface, a cold front will advance eastward through the southern and central Appalachians. Ahead of the front, moisture advection will take place from the eastern Gulf Coast States northward to the Mid-Atlantic, maintaining or increasing surface dewpoints into the lower to mid 60s F in most areas. Thunderstorms are expected to continue throughout the morning as the front progresses eastward. Strengthening low-level flow ahead of the system will result in a gradual increase in convective coverage throughout the day over the moist sector. In spite of abundant cloud cover and weak instability, an isolated severe threat is expected to develop ahead of the front. Marginally severe wind gusts will be the primary threat from northern Florida northward into the western and central Carolinas and into the Mid-Atlantic. Over the eastern Carolinas, the severe threat is expected to be greater due to a number of factors. First, model forecasts suggest that a corridor of stronger instability will develop by afternoon from far eastern South Carolina into east-central North Carolina, where MLCAPE is expected to peak around 1000 J/kg. Second, a low-level jet is forecast to move through the central Carolinas during the early afternoon. The combination of stronger instability, moderate to strong deep-layer shear and increasing low-level flow will be favorable for rotating storms. As the low-level jet moves through during the early afternoon, 0-3 km storm-relative helicity is forecast to increase to around 200 m2/s2 over parts of far eastern South Carolina and eastern North Carolina, suggesting that some of the storms could develop a tornado threat. The tornado threat will likely be greatest with storms that remain discrete and develop near the moist axis. A gradual increase in storm coverage is expected during afternoon, with a mixed mode likely. Supercells and organized line segments will likely be capable of wind-damage, with the threat peaking during the early to mid afternoon. ..Broyles/Wendt.. 12/10/2023 Read more

Valid 100331Z - 100530Z The severe weather threat for Tornado Watch 717 continues. SUMMARY...The severe threat continues across Tornado Watch 717. Damaging gusts are the main threat, though a tornado could still occur. DISCUSSION...A QLCS is progressing into the western bounds of Tornado Watch 717, where strong low-level shear remains in place. Buoyancy is limited, and when considering the storm mode, damaging gusts appear to be the primary threat. Given the strong low-level shear though, a tornado or two still cannot be ruled out, particularly with any line-embedded mesovortices. ..Squitieri.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product...

MD 2316 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHEAST TENNESSEE INTO FAR SOUTHEAST KENTUCKY AND EXTREME WESTERN VIRGINIA
Mesoscale Discussion 2316 NWS Storm Prediction Center Norman OK 0853 PM CST Sat Dec 09 2023 Areas affected...portions of northeast Tennessee into far southeast Kentucky and extreme western Virginia Concerning...Severe potential...Watch unlikely Valid 100253Z - 100500Z Probability of Watch Issuance...20 percent SUMMARY...An instance or two of damaging gusts or a brief tornado may occur in association with an approaching line of storms. However, the severe threat should be sparse and a WW issuance is not expected. DISCUSSION...A QLCS continues to progress east across portions of southern KY into middle TN. However, low-level moisture and overall buoyancy are struggling to overspread far southeastern parts of KY into eastern TN, limiting the severe threat. As the axis of a LLJ overspreads the central Appalachians, strong deep-layer and low-level shear should result. The strong low-level shear suggests that a damaging gust or tornado could occur if a storm or line segment could ingest any surface-based, unstable air parcels. Nonetheless, the limited low-level moisture amid a cooling boundary layer suggests that ingesting surface-based, buoyant parcels will be challenging, so the severe threat should be sparse at best. As such, a WW issuance is not currently anticipated. ..Squitieri/Goss.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RLX...MRX...JKL...

MD 2315 CONCERNING TORNADO WATCH 716... FOR CENTRAL/SOUTHERN MISSISSIPPI INTO CENTRAL ALABAMA
Mesoscale Discussion 2315 NWS Storm Prediction Center Norman OK 0829 PM CST Sat Dec 09 2023 Areas affected...Central/southern Mississippi into central Alabama Concerning...Tornado Watch 716... Valid 100229Z - 100430Z The severe weather threat for Tornado Watch 716 continues. SUMMARY...Tornadoes and damaging winds will remain possible through the evening. Discrete storms ahead of the cold front would pose a higher tornado threat, but their maturation is uncertain. A downstream watch is likely for parts of central/southern Alabama in the next couple of hours. DISCUSSION...Convection continues to become more linear along the cold front advancing through Mississippi into northwestern Alabama. This general trend should continue as the main synoptic trough continues east/southeast. A few more discrete elements have been noted in east-central Mississippi. While the longevity of these storms is not certain, they would pose a greater tornado threat and may reach the edge of WW 716 sooner should they mature. That being said, the cold front will likely be the zone for severe storms this evening. Objective mesoanalysis and the KBMX VAD suggest sufficient low-level shear for tornadoes. Furthermore, an increase in low-level winds is expected in parts of Alabama later tonight which would promote an increase in QLCS tornado potential. Damaging winds can also be expected, particularly with any QLCS circulations. A new tornado watch is likely for parts of central into southern Alabama within the next couple of hours. The exact timing of the watch will be somewhat dependent on whether cellular convection matures ahead of the line. ..Wendt.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product...

Valid 100218Z - 100345Z The severe weather threat for Tornado Watch 715 continues. SUMMARY...The severe threat continues across Tornado Watch 715. Damaging gusts appear to be the main threat, though a tornado or two cannot be ruled out over the next few hours. DISCUSSION...Thunderstorms have consolidated into a QLCS across middle TN into northern AL. Buoyancy continues to gradually wane over the region, though impressive shear profiles remain (i.e. the latest HTX VAD, which shows an elongated, curved hodograph). Given the linear storm mode, damaging gusts should be the main threat as the QLCS progresses across middle TN and northern AL (the remainder of Tornado Watch 715). However, given the impressive shear profiles, any portion of the line where a sustained mesovortex can develop may support the development of a tornado. ..Squitieri.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product...
