Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Sat Jun 08 2024 Valid 090100Z - 091200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM EAST-CENTRAL CO INTO WESTERN/CENTRAL KS... ...SUMMARY... Severe thunderstorms capable of producing wind gusts of 70-85 mph and large hail are expected to move from western into central Kansas through the evening. Strong to severe storms also remain possible from southeast Kansas into southern Missouri this evening into the overnight hours. ...Western into central KS... Multiple storm clusters with some embedded supercells are ongoing from eastern CO into western KS this evening, with a short-term threat of large to very large hail, severe gusts, and possibly a tornado. With time, consolidation into a larger storm cluster and possibly an MCS remains possible, which could result in an increasing threat for damaging severe gusts in the 70-85 mph range across parts of western into south-central KS later this evening. See MCD 1208 for more information. ...Southeast KS/southern MO...extreme northeast OK/northern AR... Several strong to severe storms have developed this evening across parts of southern MO, in the vicinity of a weakly confluent surface boundary. Strong instability and sufficient deep-layer shear will continue to support occasional supercells capable of producing large hail, damaging wind, and possibly a tornado. See MCD 1207 for more information regarding the short-term threat in this area. Some modest upscale growth of ongoing convection is possible with time, which could spread a damaging-wind threat toward parts of the mid MS/lower OH Valleys and potentially into western TN. Overnight, multiple storm clusters and possibly an MCS may move across from western into southern KS and southwest MO, and perhaps adjacent portions of extreme northern OK/AR. The longevity of the severe threat with the overnight storms remains uncertain with CINH expected to increase substantially with time, but at least an isolated threat of damaging wind and perhaps some hail could persist through the end of the forecast period. ...Northern CA into southern/eastern OR... High-based convection is ongoing early this evening from extreme northern CA into southern OR. Isolated downbursts will remain possible for a few hours this evening before convection subsides later tonight. ..Dean.. 06/09/2024 Read more

MD 1205 CONCERNING SEVERE THUNDERSTORM WATCH 398... FOR PORTIONS OF NORTHEASTERN COLORADO
Mesoscale Discussion 1205 NWS Storm Prediction Center Norman OK 0539 PM CDT Sat Jun 08 2024 Areas affected...Portions of northeastern Colorado Concerning...Severe Thunderstorm Watch 398... Valid 082239Z - 090045Z The severe weather threat for Severe Thunderstorm Watch 398 continues. SUMMARY...A localized corridor of significant severe-gust potential (75-85 mph) is evident for the next few hours across portions of northeast Colorado. Sporadic large hail and brief tornadoes are also possible. DISCUSSION...An upscale-growing cluster of storms is tracking southeastward at around 25-30 kt across portions of northeastern CO -- generally between I-70 and I-76. Gusts upwards of 70 mph have been observed with these storms. During the next few hours, continued upscale growth/cold pool consolidation is expected, aided by a glancing shortwave trough (evident in water-vapor imagery) over far northeastern CO. Earlier heating of a relatively moist boundary layer (middle/upper 50s dewpoints) beneath steep midlevel lapse rates should support continued surface-based inflow for intensifying updrafts at the leading edge of the convective line. And, around 50 kt of westerly/line-orthogonal 0-6 km shear (sampled by regional VWP) should aid in organized embedded updrafts with instances of deep/persistent rotation. As a result, the organizing cold pool and embedded supercell/mesovortex structures will be capable of producing significant gusts of 75-85 mph as it continues southeastward for the next few hours. Sporadic large hail and brief tornadoes will also be possible, especially with the embedded supercells/mesovorticies. ..Weinman.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1206 CONCERNING SEVERE THUNDERSTORM WATCH 398... FOR PORTIONS OF SOUTHEAST AND EAST-CENTRAL CO INTO FAR SOUTHWEST/WEST-CENTRAL KS
Mesoscale Discussion 1206 NWS Storm Prediction Center Norman OK 0620 PM CDT Sat Jun 08 2024 Areas affected...Portions of southeast and east-central CO into far southwest/west-central KS Concerning...Severe Thunderstorm Watch 398... Valid 082320Z - 090045Z The severe weather threat for Severe Thunderstorm Watch 398 continues. SUMMARY...Risk of very large hail (up to 2.75 inches), significant gusts (70-80 mph), and a couple tornadoes continues across parts of Severe Thunderstorm Watch 398. DISCUSSION...Latest radar data from KGLD/KPUX depicts a pair of intense discrete supercells tracking generally east/southeastward at around 20 kt over Kit Carson, Cheyenne, and Lincoln Counties in east-central CO. A tornado and baseball-sized hail has been reported with the northern/eastern supercell. These storms are in a very favorable environment for the maintenance of supercells, with moist/backed easterly surface winds (lower 60s dewpoints) beneath a belt of 40-50-kt midlevel westerlies (per regional VWP). Additionally, ample clockwise low-level hodograph curvature (around 250 m2/s2 effective SRH) should support continued strong low/midlevel mesocyclones given the seperated/discrete mode. As a result, very large hail (up to 2.75 inches) and a couple tornadoes are the main concern with these storms, with locally damaging gusts also probable. Farther south over Otero and Bent Counties in southeastern CO, an intense line segment has evolved in a moderately unstable air mass. 40 kt of effective shear orthogonal to the line and a moist/well-mixed boundary layer should support the maintenance or even intensification of these storms as they continue eastward. Significant gusts of 70-80 mph could accompany this activity. A brief mesovortex tornado or two is also possible with these storms, given the ample low-level SRH described above. ..Weinman.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 398 NWS Storm Prediction Center Norman OK 1225 PM MDT Sat Jun 8 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado Northwest Kansas Southwest Nebraska Far Southeast Wyoming * Effective this Saturday afternoon and evening from 1225 PM until 700 PM MDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 85 mph possible Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible SUMMARY...Thunderstorms will continue to increase in coverage and intensity this afternoon as they spread eastward from the Front Range across the central High Plains. Initially large to very large hail will be the main threat with more discrete cells. A transition to a greater threat for significant severe winds will likely occur as a bowing cluster eventually develops later this afternoon into the early evening. The severe thunderstorm watch area is approximately along and 115 statute miles north and south of a line from 10 miles west of Denver CO to 25 miles east northeast of Burlington CO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 75 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 28035. ...Gleason Read more
