Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0812 PM CDT Mon Jul 29 2024 Valid 300100Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE CENTRAL/NORTHERN PLAINS...AND ALSO FROM CENTRAL/SOUTHERN LL/IN INTO SOUTHWEST OH AND MUCH OF KY... ...SUMMARY... Severe storms capable of large hail and wind gusts of 60-80 mph remain possible tonight across parts of the central and northern Plains. Another area of severe storms, with potential for damaging wind, isolated hail, and a couple of tornadoes, will affect portions of central/southern Illinois and Indiana into Kentucky tonight. ...Central/northern Plains... One intense thunderstorm cluster has evolved this evening across south-central SD, with another developing across northern SD/southern ND. Moderate to strong buoyancy and effective shear of 30-40 kt (as noted on 00Z regional soundings) will continue to support organized severe-thunderstorm potential. Any remaining discrete cells will continue to pose a threat of large hail, while the developing storm clusters could pose an increasing threat of severe gusts (potentially greater than 75 mph) through the evening. The Slight Risk has been expanded south and east to cover the potential severe-wind threat into late tonight. See MCD 1732 for more information regarding the threat across parts of southeast SD into eastern NE and western IA. ...IL/IN/KY vicinity... Robust storms are beginning to develop across parts of central IL/IN this evening, within an environment characterized by very rich low-level moisture, strong buoyancy, and moderate northwesterly deep-layer shear. Initial discrete development could pose a threat of hail and a couple of tornadoes, with some increase in low-level shear expected through the evening. Eventually, an upscale-growing cluster may develop and move southeastward, with an increasing damaging-wind threat into parts of KY. ...GA... A few stronger southward-moving storm clusters persist this evening across parts of western/central GA. These could continue to pose a short-term threat of damaging wind, before an expected weakening trend later tonight. ..Dean.. 07/30/2024 Read more

MD 1731 CONCERNING SEVERE THUNDERSTORM WATCH 561... FOR PORTIONS OF SOUTH-CENTRAL NORTH DAKOTA AND NORTH-CENTRAL SOUTH DAKOTA
Mesoscale Discussion 1731 NWS Storm Prediction Center Norman OK 0649 PM CDT Mon Jul 29 2024 Areas affected...Portions of south-central North Dakota and north-central South Dakota Concerning...Severe Thunderstorm Watch 561... Valid 292349Z - 300115Z The severe weather threat for Severe Thunderstorm Watch 561 continues. SUMMARY...Severe wind gusts and large hail remain possible across Severe Thunderstorm Watch 561. DISCUSSION...A north/south-oriented broken line segment has shown signs of recent intensification across portions of northwestern SD into southwestern ND as of 2340Z -- with several deep/embedded rotating cores along the consolidating cold pool. Over the next hour or so, this trend may continue as the convective line continues eastward. This will be aided by moderate surface-based pre-convective instability (increasing with eastward extent) and around 40 kt of 0-6 km shear (per KBIS VWP) with a favorable line-normal component to the gust front. Given steep deep-layer lapse rates ahead of the line, severe gusts upwards of 65-75 mph will be possible, along with isolated large hail. Ahead of the line, a more discrete supercell mode persists, and these storms will pose the greater risk of large to very large hail in the near-term. ..Weinman.. 07/29/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1730 CONCERNING SEVERE THUNDERSTORM WATCH 561... FOR PORTIONS OF CENTRAL/SOUTHERN SOUTH DAKOTA AND FAR NORTH-CENTRAL NEBRASKA
Mesoscale Discussion 1730 NWS Storm Prediction Center Norman OK 0609 PM CDT Mon Jul 29 2024 Areas affected...Portions of central/southern South Dakota and far north-central Nebraska Concerning...Severe Thunderstorm Watch 561... Valid 292309Z - 300045Z The severe weather threat for Severe Thunderstorm Watch 561 continues. SUMMARY...Large to very large hail and severe wind gusts will continue with the most intense thunderstorms across Severe Thunderstorm Watch 561. DISCUSSION...Latest radar data from KUDX indicates semi-discrete, splitting supercells generally tracking eastward across central/southern SD into far north-central NE this evening. These storms have been producing 60-65 mph gusts and hail up to 1.75 inches. Moderately unstable surface-based inflow -- characterized by upper 80s/lower 90s temperatures amid upper 60s/lower 70s dewpoints should support the maintenance or even intensification of these storms with eastward extent. Long/mostly straight hodographs (with some low-level clockwise curvature) should favor a continuation of splitting, semi-discrete supercells in the near-term. These storms will be capable of producing locally severe gusts near 75 mph and very large hail to around 2.5 inches in diameter. In the near-term, this is especially the case with a dominant right-mover supercell cluster moving across portions of Jones and Mellette Counties, SD. While less certain, the aforementioned hodograph structure and semi-discrete supercell mode may support a brief tornado as well. With time, there may be a tendency for some of these storms to grow upscale as they intercept the richer boundary-layer moisture with eastward extent. This would favor an increasing damaging-wind risk. ..Weinman.. 07/29/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FSD...ABR...LBF...UNR...
