MD 2120 CONCERNING TORNADO WATCH 684... FOR FROM JACKSONVILLE NORTHWARD ACROSS MUCH OF SOUTHEAST GEORGIA AND THE CAROLINAS
Mesoscale Discussion 2120 NWS Storm Prediction Center Norman OK 0539 PM CDT Thu Sep 26 2024 Areas affected...from Jacksonville northward across much of southeast Georgia and the Carolinas Concerning...Tornado Watch 684... Valid 262239Z - 270315Z The severe weather threat for Tornado Watch 684 continues. SUMMARY...The risk of tornadoes is likely to increase/spread northward through tonight across southeast Georgia, eastern South Carolina and southeast North Carolina. An isolated strong tornado cannot be ruled out. DISCUSSION...Surface analysis shows a warm front/boundary from southern GA to just off the SC Coast this evening. South of this boundary, deeper tropical moisture exists with upper 70s F to near 80 F dewpoints, and as such, MLCAPE near the coast is already near 1000 J/kg, with larger values over 1500 J/kg off the eastern FL Peninsula. As Hurricane Helene continues northward this evening, wind fields across the region will strengthen, with 850 mb winds increasing dramatically after about 03Z. As such, the surface warm front will move ashore into SC, with further destabilization over parts of southeast GA as well. Effective SRH of 300-500 m2/s2 coincident with the instability axis will be common this evening, with even stronger shear but lower instability along the western fringe of the warm sector. An initial band of convection currently extends into the Jacksonville FL area, and embedded cells could rotate an produce a brief tornado. Additional bands of storms are likely to develop this evening and tonight as the warm advection processes increase. Given such strong shear, an isolated strong tornado cannot be ruled out late. ..Jewell.. 09/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2121 CONCERNING TORNADO WATCH 683...685... FOR MUCH OF THE FLORIDA PENINSULA AND FAR SOUTHERN GEORGIA
Mesoscale Discussion 2121 NWS Storm Prediction Center Norman OK 0602 PM CDT Thu Sep 26 2024 Areas affected...Much of the Florida Peninsula and far southern Georgia Concerning...Tornado Watch 683...685... Valid 262302Z - 270030Z The severe weather threat for Tornado Watch 683, 685 continues. SUMMARY...The tornado threat across much of the Florida Peninsula and southern Georgia will continue well into the evening hours. A replacement tornado watch will be needed soon. DISCUSSION...The latest satellite, lightning, and radar imagery associated with Helene, and its extrapolation, continue to suggest the potential for several more bands of low-topped thunderstorms extending over much of the FL Peninsula and far southern GA through tonight. Increasing low-level flow associated with Helene remains apparent on the TBW VWP, with a slow increase of around 5-10 kt of shear observed in the lowest 1 km over the past hour. Although buoyancy will slowly decrease overnight, the aforementioned shear will yield 0-1 km SRH around 400-700 m2/s2 for several hours within all eastern quadrants of Helene. Brief tornadoes are expected within this zone of substantial, increasing low-level shear as far north as the eastern FL Panhandle. A new tornado watch will likely be issued within the next hour. ..Barnes/Gleason.. 09/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MFL...MLB...TBW...JAX...TAE...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0406 PM CDT Thu Sep 26 2024 Valid 281200Z - 041200Z Along the northern periphery of an expansive midlevel anticyclone centered over the Four Corners vicinity, a midlevel trough -- accompanied by strong deep-layer westerly flow -- will track eastward from the Pacific Northwest across the northern Plains/Upper MS Valley through Day 6/Tuesday. Thereafter, an additional midlevel trough will advance eastward across the Northwest. On Day 4/Sunday, strong westerly flow accompanying the midlevel trough will cross the Northwest, promoting locally dry/windy conditions along/east of the Cascades. While this could favor elevated to perhaps locally critical fire-weather conditions, cool post-frontal surface temperatures limits confidence in the overlap of strong winds and warm/dry conditions. Farther east, lee troughing over the High Plains will favor dry/breezy conditions over the central Rockies and Plains. Similarly, confidence in the overlap of the strongest winds and low RH is currently too low to add Critical probabilities at this time. By Day 5/Monday, a swath of strong post-frontal surface winds will overspread the northern/central Plains, with an associated increase in fire-weather concerns where fuels are dry. 40-percent Critical probabilities have been added where confidence is highest in the overlap of strong winds and low RH. Thereafter, the strong westerly flow aloft across the northern CONUS could support additional fire-weather concerns -- especially across portions of the central Rockies/Plains. However, the details are unclear at this time. ..Weinman.. 09/26/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 2117 CONCERNING TORNADO WATCH 683... FOR PORTIONS OF THE WESTERN FLORIDA PENINSULA
Mesoscale Discussion 2117 NWS Storm Prediction Center Norman OK 0214 PM CDT Thu Sep 26 2024 Areas affected...portions of the western Florida Peninsula Concerning...Tornado Watch 683... Valid 261914Z - 262115Z The severe weather threat for Tornado Watch 683 continues. SUMMARY...The tornado risk associated with low-topped supercells in the bands of Helene continues across all of WW683. The greatest risk will likely be focused over the western half of FL where low-level shear is stronger. DISCUSSION...As of 1915 UTC, the center of Hurricane Helene was located near 26.4N 85.0W or about 195 MI...315 KM SW of Tampa FL per the latest NHC information. As the outer bands of Helene continue to move over the FL peninsula, cloud breaks between the bands were supporting heating and weak destabilization. Several bands of showers and low-topped thunderstorms were located off the western Coast, with a less organized band over the central and eastern parts of FL. Low-level shear (Tampa VAD 350-450 m2/s2 0-1km SRH) is strongest to the west, closer to the center of the circulation. However, low-level shear remains supportive of tornadoes over much of FL. Given favorably strong/weakly veering low-level flow indicated across the entire area, risk for brief tornadoes continues with any cellular convection that evolves. ..Lyons.. 09/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2118 CONCERNING TORNADO WATCH 685... FOR PORTIONS OF THE FLORIDA PANHANDLE AND SOUTHWEST GEORGIA
Mesoscale Discussion 2118 NWS Storm Prediction Center Norman OK 0240 PM CDT Thu Sep 26 2024 Areas affected...portions of the Florida Panhandle and southwest Georgia Concerning...Tornado Watch 685... Valid 261940Z - 262145Z The severe weather threat for Tornado Watch 685 continues. SUMMARY...The tornado risk continues across WW 684. The focus should remain close to a weak front/baroclinic zone across the FL Panhandle and Southwest GA. DISCUSSION...Ahead of Hurricane Helene located near 26.4N 85.0W or 195 MI...315 km SW of Tampa, the environment remains favorable for a few tornadoes. Inland advection of a very moist tropical air mass continues along and east of a weak stalled frontal boundary, with weak buoyancy (~1000 J/kg MUCAPE) supporting numerous low-topped convective elements in the outer bands. Low-level hodographs have also continued to expand with the TLH VAD showing strong low-level turning and 250-350 m2/s2 o-1km SRH. As low-topped offshore cells with low-level rotation move northwestward near Apalachicola, a few tornadoes are possible. The greatest focus for tornadoes appears to be along and east of the boundary, where low-level shear should be somewhat enhanced. However, as Helene approaches later this afternoon, low-level shear will continue to increase, supporting a risk for tornadoes across much of the watch area. ..Lyons.. 09/26/2024 ...Please see www.spc.noaa.gov for graphic product...

Valid 262010Z - 262215Z The severe weather threat for Tornado Watch 685 continues. SUMMARY...Bands of low-topped storms will continue to move onshore through the afternoon and evening. Low-level shear is supportive of a tornado risk and will continue to increase tonight. DISCUSSION...As of 20 UTC, outer rain bands associated with Hurricane Helene were continuing to move onshore across parts of eastern GA and SC. Low-level easterly flow is slowly increased supporting continued inland advection of a very warm and moist tropical air mass. Despite very poor mid-level lapse rates, weak to moderate buoyancy continues to support numerous convective elements moving onshore within these bands. Strong low-level shear (0-1km SRH 300-400 m2/s2) is in place and will continue to intensify this afternoon and evening as Helene approaches shore. Low-topped supercells will continue to pose a tornado risk as they move onshore. The risk may be focused near a weak frontal zone where low-level shear is enhanced further. ..Lyons.. 09/26/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0234 PM CDT Thu Sep 26 2024 Valid 262000Z - 271200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS COASTAL AREAS OF NORTHEAST FLORIDA...GEORGIA...SOUTH CAROLINA...AND FAR SOUTHERN NORTH CAROLINA... ...SUMMARY... Several tornadoes remain possible this afternoon into tonight across the coastal Southeast in association with Hurricane Helene. The greatest threat is expected across parts of Florida into southeast Georgia, the Midlands and Low Country of South Carolina, and southern North Carolina. ...20Z... The Day 1 Convective Outlook remains on track. Multiple rainbands with embedded low-topped, rotating storms continue to progress across the FL Panhandle into central GA and SC. As the center of Hurricane Helene approaches the FL coastline later this evening, the vertical wind (and associated shear) profiles should increase further across northern FL into the Carolinas. Large, curved hodographs will support tornado potential with any embedded supercell structures that can develop amid surface-based buoyancy. The latest CAM guidance depicts an arc of low-topped supercells to the northeast of Helene's center moving across central and eastern SC between 06-12Z, when tornado potential will be maximized. If enough surface-based buoyancy can advect inland, a strong tornado could develop closer to the SC coastline. ..Squitieri.. 09/26/2024 .PREV DISCUSSION... /ISSUED 1127 AM CDT Thu Sep 26 2024/ ...Florida/Georgia into the Carolinas... Hurricane Helene is currently centered about 200 miles southwest of SRQ. This system is characterized by a very broad/expansive wind field, with the VAD profiles at JAX and CLX showing 50 and 35 kt at 2 km, respectively. Stronger low-level winds are already in place across FL. Rotation has been noted in cells both off the central FL Panhandle south of TLH as well as from coastal GA into the SC Low Country. The general trend of rotation within the deeper, more cellular convection is expected to continue throughout the day into the evening across the entire region, with some chance for an increased frequency of rotating cells given the strengthening wind profiles. Best overlap between modest buoyancy and veering low-level wind profiles is still expected to occur from southeast GA northward into coastal SC and far southern NC (i.e. ILM vicinity). For much of this region, the higher dewpoints currently remain offshore, but additional advection inland is anticipated as the system moves northward. This additional low-level moisture should increase buoyancy slightly, which is expected to result in a relatively higher tornado threat. This relatively higher tornado risk is expected from 04Z to 18Z Friday, which bridges the Day 1 and Day 2 periods. As such, additional information regarding the tornado risk for this area can be found in the Day 2 Convective Outlook. Read more
