Severe Storms

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0738 PM CDT Sat Jun 15 2024 Valid 160100Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MID-MISSOURI VALLEY REGION AND THE NORTHERN HIGH PLAINS... ...SUMMARY... Scattered severe thunderstorms with damaging winds and large hail remain possible this evening across the Mid-Missouri Valley, and also from eastern Montana to the western/central Dakotas. A few tornadoes could occur in eastern Nebraska and western Iowa, with isolated significant severe hail and wind possible across parts of the northern Plains. ...01z Update... Early-evening water-vapor imagery depicts a well-defined mid-level vort over north-central KS lifting northeast toward the Mid-MO Valley. Two clusters of severe thunderstorms have evolved ahead of this feature: 1) northeast Nebraska, 2) southeast Nebraska into northeast Kansas. The northeast NE cluster is comprised of several supercells that have generated tornadoes at times. The southern-most complex has evolved into a linear MCS that is tracking toward northwest MO/southwest IA, and is producing severe wind gusts. Both of these clusters are supported by the aforementioned short wave which will encourage an increase in the LLJ across central IA into western WI later this evening. This should allow strong/severe thunderstorms to spread into the Mid/Upper MS Valley after sunset. Upstream across the northern High Plains, strongly diffluent high-level flow is noted across eastern MT into the western Dakotas ahead of a pronounced northern-Rockies short-wave trough. This short wave will shift into eastern MT later tonight as 500mb speed max rotates across northeast MT into southeast SK. Strong/severe thunderstorms will be noted ahead of the surging cold front which should advance across the western Dakotas by 06z. ..Darrow.. 06/16/2024 Read more

MD 1276 CONCERNING TORNADO WATCH 418... FOR EASTERN NE...NORTHEAST KS...SOUTHEAST SD...WESTERN IA
Mesoscale Discussion 1276 NWS Storm Prediction Center Norman OK 0544 PM CDT Sat Jun 15 2024 Areas affected...Eastern NE...northeast KS...southeast SD...western IA Concerning...Tornado Watch 418... Valid 152244Z - 160015Z The severe weather threat for Tornado Watch 418 continues. SUMMARY...The tornado threat may increase into this evening, along with continued hail and damaging-wind potential. DISCUSSION...Supercells have recently developed across northeast NE, with another somewhat less organized cluster moving northeastward out of southeast NE. Gradual heating and moistening through the day has resulted in moderate to strong destabilization, with MLCAPE of 2000-3000 J/kg across the region per recent objective mesoanalyses. The low-level wind profile depicted by KOAX and KFSD VWPs is favorable for potentially tornadic supercells, with favorable hodograph curvature (0-1 km SRH of greater than 150 m2/s2) and 30-40 kt of flow at 1-3 km above the surface. Rather modest midlevel flow is less favorable, though, which could result in a tendency toward storm clustering with time. The greatest short-term tornado threat appears to reside across northeast NE, given the presence of ongoing semi-discrete supercells. However, the environment downstream of the southeast NE storm cluster also remains favorable for a tornado or two as convection approaches the MO River Valley early this evening, along with some threat for isolated hail and damaging wind. ..Dean.. 06/15/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1277 CONCERNING SEVERE THUNDERSTORM WATCH 419... FOR PARTS OF NORTHEAST KS
Mesoscale Discussion 1277 NWS Storm Prediction Center Norman OK 0605 PM CDT Sat Jun 15 2024 Areas affected...Parts of northeast KS Concerning...Severe Thunderstorm Watch 419... Valid 152305Z - 160030Z The severe weather threat for Severe Thunderstorm Watch 419 continues. SUMMARY...Some threat for severe gusts will persist into early evening. DISCUSSION...A small thunderstorm cluster with a history of producing severe gusts is moving across northeast KS. A shortwave trough moving across central KS is likely aiding this storm cluster, which will likely persist in some form through early evening. While there has been some tendency for outflow to outpace the leading edge of convection, some reintensification of this cluster will be possible as it moves into a downstream environment characterized by richer low-level moisture and MLCAPE in excess of 2500 J/kg. Given the current outflow-dominant cluster mode, severe gusts will likely continue to be the primary threat in the short term, though the downstream environment would also favor some potential for hail and possibly a tornado, if any more cellular development can occur along/ahead of the ongoing storms. ..Dean.. 06/15/2024 ...Please see www.spc.noaa.gov for graphic product...
