MD 1198 CONCERNING SEVERE THUNDERSTORM WATCH 397... FOR PORTIONS OF SOUTH-CENTRAL/SOUTHEAST NE AND NORTH-CENTRAL/NORTHEAST KS
Mesoscale Discussion 1198 NWS Storm Prediction Center Norman OK 0912 PM CDT Fri Jun 07 2024 Areas affected...Portions of south-central/southeast NE and north-central/northeast KS Concerning...Severe Thunderstorm Watch 397... Valid 080212Z - 080345Z The severe weather threat for Severe Thunderstorm Watch 397 continues. SUMMARY...Severe gusts of 70-80 mph and isolated large hail remain possible with a southward-moving complex of storms in Severe Thunderstorm Watch 397. DISCUSSION...Latest radar data from KUEX shows a gradually upscale-growing complex of storms tracking southward at around 30-35 kt across south-central Nebraska. While a consolidated cold pool appears to be intensifying, intense/separated supercell structures remain evident along/immediately behind the gust front. Given these persistent separated supercells and a favorable supercell wind profile downstream (upwards of 70 kt of effective shear and a large/looping hodograph), instances of large to very large hail up to around 2.75 inches remain possible in the near term. However, the overall severe risk should be transitioning to a damaging-wind threat, owing to the gradual upscale growth. This upscale growth should be aided by increasingly orthogonal deep-layer shear to the consolidated cold pool and a strengthening southerly low-level jet (around 40 kt sampled by downstream VWP). If more robust upscale growth does occur, 70-80 mph gusts could become more common. ..Weinman.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OAX...TOP...ICT...GID...

WW 397 SEVERE TSTM IA KS MO NE 072250Z - 080400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 397 NWS Storm Prediction Center Norman OK 550 PM CDT Fri Jun 7 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Extreme Southwest Iowa Central and Northeast Kansas Northwest Missouri South central and Southeast Nebraska * Effective this Friday afternoon and evening from 550 PM until 1100 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely A tornado or two possible SUMMARY...Severe thunderstorms are expected to increase in coverage while moving southeast across the watch area this evening. Damaging winds will become an increasing concern, with isolated gusts of up to 75 mph possible. Large hail, possibly up to 2.5 inches in diameter, may occur with the strongest storms. A tornado or two will also be possible within bowing segments as storms organize into a line. The severe thunderstorm watch area is approximately along and 85 statute miles north and south of a line from 40 miles north of Russell KS to 15 miles south of Falls City NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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 395...WW 396... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 30035. ...Bunting Read more

MD 1197 CONCERNING SEVERE THUNDERSTORM WATCH 396...397... FOR PARTS OF NORTHWEST INTO CENTRAL KS
Mesoscale Discussion 1197 NWS Storm Prediction Center Norman OK 0905 PM CDT Fri Jun 07 2024 Areas affected...Parts of northwest into central KS Concerning...Severe Thunderstorm Watch 396...397... Valid 080205Z - 080300Z The severe weather threat for Severe Thunderstorm Watch 396, 397 continues. SUMMARY...Wind gusts of 65-80 mph remain possible this evening as a storm cluster moves east-southeastward, along with some potential for hail and possibly a tornado. DISCUSSION...An earlier supercell cluster across northwest KS has shown some signs of accelerating east-southeastward, with less of a discrete character compared to earlier this evening. This may indicate a transition to more of a severe-wind threat, as evidenced by recent mesonet gusts of 60-80 mph across Trego County, KS. Despite a tendency for gradually increasing CINH with time tonight, a strengthening southerly low-level jet (as noted on the KICT VWP) may help to sustain this cluster as it moves east-southeastward, with a continued short-term threat for severe gusts potentially in the 65-80 mph range. In addition, increasing low-level shear/SRH with time and southeastward extent could support the threat of a tornado. MLCAPE in excess of 2000 J/kg and strong effective shear will also continue to support a hail threat with any stronger cells embedded within the cluster as it approaches parts of central KS. ..Dean.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1196 CONCERNING SEVERE THUNDERSTORM WATCH 395...397... FOR PORTIONS OF SOUTH-CENTRAL NEBRASKA
Mesoscale Discussion 1196 NWS Storm Prediction Center Norman OK 0651 PM CDT Fri Jun 07 2024 Areas affected...Portions of south-central Nebraska Concerning...Severe Thunderstorm Watch 395...397... Valid 072351Z - 080115Z The severe weather threat for Severe Thunderstorm Watch 395, 397 continues. SUMMARY...Large hail, damaging winds, and a tornado or two remain possible with thunderstorms tracking south-southeastward across south-central Nebraska this evening. DISCUSSION...Latest radar data from KLNX indicates several discrete/semi-discrete supercells tracking south-southeastward across south-central Nebraska this evening. In particular, one longer-lived intense supercell currently over southeastern Custer County poses the greatest risk for large hail, damaging winds, and a tornado. Downstream of this storm, VWP data shows a large, clockwise-curved low-level hodograph (around 200 m2/s2 0-1 km SRH), which will support ample streamwise vorticity ingestion, given middle 60s dewpoints and moderate surface-based instability. This supercell may persist for another 60-90 minutes, with large hail up to 2.5 inches, locally damaging gusts up to 75 mph, and a tornado possible. Trailing supercell development along the outflow boundary will also pose a risk for large hail and damaging winds, and a brief tornado cannot be ruled out. Farther east over Nance County, a locally upscale-growing storm cluster is moving southeast at 30-35 kt, and this storm may pose a greater damaging-wind risk, with large hail also possible. ..Weinman/Majchrowski.. 06/07/2024 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0751 PM CDT Fri Jun 07 2024 Valid 080100Z - 081200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL PLAINS... ...SUMMARY... Severe thunderstorms will spread southeast across the central Plains this evening. Damaging winds and large hail are the primary threats. ...Central Plains... Weak short-wave trough has topped the western US ridge and is now digging southeast across the central Plains. Robust convection has evolved ahead of this feature with a corridor of mixed supercells and multi cell clusters. An east-west band of severe thunderstorms extends across southern NE and this activity is propagating southeast immediately ahead of the short wave. 1km AGL inflow is roughly 30-35kt into this activity and LLJ is forecast to strengthen markedly this evening into northeast KS. This complex should grow upscale as it advances downstream. If this occurs, an organized damaging wind event could materialize along the leading edge of the cold-pool enhanced squall line. More isolated convection is noted across the High Plains of western KS and these storms should remain somewhat isolated as they propagate southeast. A more concentrated band of high-based convection has evolved from northeast NM into the eastern OK Panhandle. This activity has the potential to produce severe wind gusts as it spreads east this evening. ..Darrow.. 06/08/2024 Read more
