MD 1369 CONCERNING SEVERE THUNDERSTORM WATCH 445... FOR PARTS OF NE INTO FAR SOUTHEAST SD...NORTHWEST IA...AND FAR SOUTHWEST MN
Mesoscale Discussion 1369 NWS Storm Prediction Center Norman OK 0825 PM CDT Fri Jun 21 2024 Areas affected...Parts of NE into far southeast SD...northwest IA...and far southwest MN Concerning...Severe Thunderstorm Watch 445... Valid 220125Z - 220300Z The severe weather threat for Severe Thunderstorm Watch 445 continues. SUMMARY...An isolated severe hail/wind threat continues this evening. DISCUSSION...Training cells are ongoing early this evening across south-central into eastern NE along and south of a front. The downstream 00Z sounding from OAX shows generally poor mid-level lapse rates, with a long/skinny MLCAPE profile. Still, enough low-level and deep-layer shear remains present to support organized convection, including the potential for supercells. Any thunderstorm which can remain at least semi-discrete should have some hail threat, even with the poor lapse rates aloft and associated warm mid-level temperatures. An isolated threat for severe/damaging winds may also continue, especially if thunderstorms can congeal into a small bowing cluster this evening in tandem with a gradually strengthening low-level jet. The overall tornado threat may be tempered by continued messy storm modes, although low-level shear should gradually increase this evening. Depending on convective trends, a local extension in area for Severe Thunderstorm Watch 445 may be warranted across parts of central/eastern NE. ..Gleason.. 06/22/2024 ...Please see www.spc.noaa.gov for graphic product...

Widely scattered strong to severe thunderstorm development remains possible this evening across the Rockies, adjacent portions of the Southwest, and parts of the central Great Plains into the Upper Midwest. ...01Z Update... Downstream of broad, weak mid/upper troughing, widely scattered strong to severe thunderstorm activity persists across the Rockies, adjacent portions of the Southwest and Great Plains, with additional widely scattered activity focused near the northern periphery of prominent mid-level ridging centered over the Mid South. While convection across most areas already appears in the process of slowly waning, an evolving cluster of storms across parts of central into northeastern Nebraska could still strengthen and organize further this evening into the overnight hours, accompanied by increasing risk for potentially damaging wind gusts. The environment across the Missouri Valley, ahead of it, remains potentially unstable, with CAPE on the order of 1500-2000+ J/kg, as a belt of 30-40+ kt south-southwesterly to westerly flow in the 850-500 mb layer noses northeast of the Kansas/Nebraska border toward the Upper Midwest. ..Kerr.. 06/22/2024 Read more

MD 1368 CONCERNING SEVERE THUNDERSTORM WATCH 442... FOR WESTERN INTO CENTRAL MONTANA
Mesoscale Discussion 1368 NWS Storm Prediction Center Norman OK 0627 PM CDT Fri Jun 21 2024 Areas affected...Western into central Montana Concerning...Severe Thunderstorm Watch 442... Valid 212327Z - 220100Z The severe weather threat for Severe Thunderstorm Watch 442 continues. SUMMARY...The strongest convection will continue southeastward this evening. Additional development may occur. Large hail and isolated severe winds are the main hazards. DISCUSSION...A few widely scattered supercells are moving slowly southeastward into parts of central Montana. This motion is generally expected to continue into the evening, as this is where the moisture axis is situated. However, some early convection has left some outflow (cooler/modestly drier) that is evident in surface observations. It is unclear how this will impact the ongoing strong/severe storms as they encounter this mesoscale environment. Additional storms may develop within the terrain or perhaps along the southern edge of the outflow. It also appears possible that a storm or two could move southeastward out of Alberta. In general, large hail (conditionally up to 2 inches with a mature supercell) and isolated strong/severe gusts are the main threats into the evening. ..Wendt.. 06/21/2024 ...Please see www.spc.noaa.gov for graphic product...
