MD 1209 CONCERNING SEVERE THUNDERSTORM WATCH 398...399... FOR EAST-CENTRAL COLORADO INTO WEST-CENTRAL KANSAS
Mesoscale Discussion 1209 NWS Storm Prediction Center Norman OK 0817 PM CDT Sat Jun 08 2024 Areas affected...East-central Colorado into west-central Kansas Concerning...Severe Thunderstorm Watch 398...399... Valid 090117Z - 090315Z The severe weather threat for Severe Thunderstorm Watch 398, 399 continues. SUMMARY...A swath of 80-95 mph gusts could continue for a few more hours with an organized thunderstorm cluster tracking east-southeastward across east-central Colorado into west-central Kansas. DISCUSSION...KGLD radar data shows an organized/upscale-growing bowing line segment (with organizing MCV and rear-inflow jet) tracking southeastward at around 30 kt across east-central CO/west-central KS immediately south of I-70. A gust of 96 mph was measured in Burlington CO with this activity, with more frequent gusts of 60-70 mph. The KGLD VWP depicts a large, clockwise-curved hodograph with around 60 kt of 0-6 km shear orthogonal to the gust front of the storm. This, combined with upper 50s/lower 60s dewpoints beneath steep midlevel lapse rates, should support the maintenance of this intense cluster as it continues east-southeastward during the next few hours. ..Weinman.. 06/09/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1207 CONCERNING SEVERE THUNDERSTORM WATCH 399... FOR SOUTHERN MISSOURI REGION
Mesoscale Discussion 1207 NWS Storm Prediction Center Norman OK 0658 PM CDT Sat Jun 08 2024 Areas affected...Southern Missouri Region Concerning...Severe Thunderstorm Watch 399... Valid 082358Z - 090130Z The severe weather threat for Severe Thunderstorm Watch 399 continues. SUMMARY...Convection should increase across ww399 this evening along with an attendant severe risk for wind/hail. DISCUSSION...Weak short-wave ridging is expected to gradually relax this evening. This is supported by a recent uptik in convection south of a weak surface boundary that is currently draped east-west, just south of I70. Visible satellite imagery depicts a considerable amount of agitated cu from southeast KS into south-central MO where several robust thunderstorm clusters are maturing. This activity is evolving within a very unstable air mass, and cloud tops suggest these updrafts are processing air efficiently. Current thinking is a considerable amount of convection may ultimately evolve across ww399 and large hail and damaging winds are possible with these storms. ..Darrow.. 06/08/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1208 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR THE WESTERN HALF OF KANSAS
Mesoscale Discussion 1208 NWS Storm Prediction Center Norman OK 0704 PM CDT Sat Jun 08 2024 Areas affected...The western half of Kansas Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 090004Z - 090130Z Probability of Watch Issuance...95 percent SUMMARY...A Severe Thunderstorm Watch will likely be issued for parts of the area by 01Z. Primary concerns are significant severe gusts up to 80 mph and large hail. DISCUSSION...During the next few hours, a mix of supercells and bowing line segments currently tracking east-southeastward across eastern CO (in Severe Thunderstorm Watch 398) will continue across the western half of Kansas. Current expectation is for much of the ongoing activity to congeal into organized clusters as they continue eastward into tonight -- given strong/persistent outflow generation. The downstream environment features middle/upper 80s temperatures amid middle/upper 60s dewpoints beneath an EML/steep lapse rate plume. The resultant moderate/strong surface-based instability should support a continued severe risk with eastward extent into tonight. Around 50 kt of westerly effective shear should also favor organized clusters capable of significant winds gusts (up to 80 mph) and instances of large hail. It is still unclear if one consolidated MCS can develop, but if this scenario unfolds, more widespread severe wind can be expected. A Severe Thunderstorm Watch will likely be issued by 01Z for much of the area. ..Weinman/Bunting.. 06/09/2024 ...Please see www.spc.noaa.gov for graphic product...

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

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
