Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1240 AM CDT Sat Jun 08 2024 Valid 081200Z - 091200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL HIGH PLAINS... ...SUMMARY... Scattered severe thunderstorms are expected to develop across the central High Plains this afternoon then spread toward south-central Kansas during the evening. Isolated severe storms may also occur across the Ozarks vicinity. ...Central Plains... Early this morning, water-vapor imagery depicts a notable short-wave trough over northern UT/western WY. This feature is forecast to advance into southeast WY/northern CO by 18z, then shift into KS during the latter half of the period. Latest model guidance suggests the primary synoptic boundary located over the Plains will drape itself near the I70 corridor early, arcing from northern KS into northeast CO. This wind shift should serve as the focus for a corridor of severe, and the boundary should gradually sag south toward the KS/OK border by the end of the period. While boundary-layer heating will prove instrumental in robust convection today, the approaching short-wave trough is expected to encourage significant organization along with early-afternoon initiation near the Front Range of southeast WY and northern CO. Forecast soundings suggest thunderstorms may develop as early as 18-19z near LAR/CYS. This activity should spread/develop southeast into eastern CO where boundary-layer heating and moist upslope flow should encourage upscale growth. Initial storm mode should be supercellular with strong surface-6km bulk shear and favorable low-level turning. NAM PFC for LIC at 09/00z exhibits MLCAPE on the order of 2500 J/kg and this should be typical across eastern CO into portions of western KS south of the front. Thermodynamic profiles favor hail in excess of 2 inches with early-mode supercells; however, severe wind threat will become more common if one or more MCSs evolve, as seem plausible given the supporting short wave. These complexes should spread across western KS toward south-central KS during the late evening hours. ...Ozarks Region... Slow-moving MCS is currently spreading across northeast KS into northern MO. This activity is forecast to advance across central MO early in the period before spreading downstream and weakening. While weak short-wave ridging will be noted in the wake of this convection, if the convective outflow is appreciable, there is some concern this boundary may drape itself across southern MO which could serve as the focus for isolated severe storms later in the afternoon. Forecast soundings exhibit strong buoyancy and modest deep-layer shear. This region may need a SLGT Risk if/when it becomes more clear a boundary will likely serve as the focus for storm initiation. ..Darrow/Weinman.. 06/08/2024 Read more

MD 1199 CONCERNING SEVERE THUNDERSTORM WATCH 397... FOR CENTRAL/EASTERN KS...EXTREME SOUTHEAST NE...WESTERN MO
Mesoscale Discussion 1199 NWS Storm Prediction Center Norman OK 1014 PM CDT Fri Jun 07 2024 Areas affected...Central/eastern KS...extreme southeast NE...western MO Concerning...Severe Thunderstorm Watch 397... Valid 080314Z - 080445Z The severe weather threat for Severe Thunderstorm Watch 397 continues. SUMMARY...Some severe-wind threat may continue into the overnight hours. WW 397 will be extended in time, with eventual downstream watch issuance possible. DISCUSSION...One long-lived storm cluster is currently moving out of south-central/southeast NE into northern KS, with another small but intense storm cluster moving eastward across central KS. The central KS cluster recently produced a 70 kt gust in Russell, and will continue to pose a threat for 65-80 mph gusts (along with isolated hail) as it moves through an environment with MLCAPE of greater than 2500 J/kg and strong effective shear. A threat for at least isolated hail and severe gusts will also accompany the northern cluster in the short term as it moves southeastward into a larger portion of northern KS. Storm evolution later tonight remains uncertain. A strong low-level jet will continue to support organized convection into the overnight hours. However, uncertainty remains regarding the potential interaction between the northern and southern cluster, and any potential for further upscale growth with time. With some severe threat likely to persist into at least the early overnight hours, WW 397 will be extended in time by 2 hours (until 1 AM CDT). Eventual downstream watch issuance remains possible, if trends support a continued organized severe risk into the overnight hours. ..Dean/Bunting.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product...

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...
