WW 585 TORNADO KS 152310Z - 160500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 585 NWS Storm Prediction Center Norman OK 610 PM CDT Thu Aug 15 2019 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of North-central and Eastern Kansas * Effective this Thursday night from 610 PM until Midnight CDT. * Primary threats include... A couple tornadoes possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Severe thunderstorms are expected to develop this evening, particularly near a stalled boundary that is oriented roughly west to east across north-central/northeast Kansas. Large hail and locally damaging winds may be the most common risks, but adequate moisture and seasonally strong low-level shear supports the possibility of tornadoes, especially across northeast/east-central Kansas. The tornado watch area is approximately along and 60 statute miles north and south of a line from 55 miles west southwest of Concordia KS to 20 miles southeast of Topeka KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). PRECAUTIONARY/PREPAREDNESS ACTIONS...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 584 NWS Storm Prediction Center Norman OK 450 PM CDT Thu Aug 15 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast Kansas Northwest Missouri Far Southeast Nebraska * Effective this Thursday afternoon from 450 PM until Midnight CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Isolated damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Strong to severe storms should continue to develop this evening and move southeastward along and north of a prior outflow boundary. Large hail will be the primary risk with this mostly elevated storms to the north of the outflow boundary. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 30 miles southwest of Falls City NE to 55 miles east northeast of Kansas City MO.

MD 1752 CONCERNING TORNADO WATCH 585... FOR NORTH-CENTRAL AND NORTHEAST KANSAS
Mesoscale Discussion 1752 NWS Storm Prediction Center Norman OK 0822 PM CDT Thu Aug 15 2019 Areas affected...north-central and northeast Kansas Concerning...Tornado Watch 585... Valid 160122Z - 160315Z The severe weather threat for Tornado Watch 585 continues. SUMMARY...Severe/isolated tornado risk continues across Tornado Watch 585. DISCUSSION...Latest radar loop shows a few intense storms across northeast Kansas, within WW 585. The storms appear to be initiating near remnant outflows, and then are propagating south-southeastward -- fed by a developing 30 to 35 kt south-southwesterly low-level jet. Along with large hail, a couple of brief tornadoes have been spotted recently -- including reports from Geary and Wabaunsee Counties in Kansas. Storms will likely persist for several hours, as the low-level jet continues to strengthen, and given the pool of strong instability just west of the ongoing storms coupled with a favorably veering/increasing wind profile with height. Risk for all hazards will continue, for at least the next few hours. ..Goss.. 08/16/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...OAX...TOP...ICT...GID...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0806 PM CDT Thu Aug 15 2019 Valid 160100Z - 161200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM EASTERN KANSAS INTO WESTERN MISSOURI... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EASTERN WYOMING INTO WESTERN NEBRASKA... ...SUMMARY... Severe thunderstorms are expected to spread southeast through eastern Kansas and western Missouri this evening with large hail, damaging wind and a couple of tornadoes. Other strong to severe storms might develop later tonight from eastern Wyoming into western Nebraska. ...Central and eastern Kansas into western Missouri... Storms that developed along a east-west oriented outflow boundary across northeastern KS are expected to persist into the overnight as they develop southeastward, eventually into western MO. The 00Z RAOB from TOP sampled the atmosphere north of the this boundary and indicates moderate instability along with 50 kt 0-6 km shear and 200+ m2/s2 0-1 km storm relative helicity. Supercells developing along and slightly to the cool side of the outflow boundary are more likely to realize the vorticity rich 0-1 km air and develop low-level mesocyclones and a tornado or two. While storms deeper into the cool side should remain elevated. Storms are expected to develop southeast through eastern KS and western MO along instability gradient supported by a strengthening low-level jet. Discrete supercells with large hail and a couple of tornadoes as the initial mode may eventually evolve into an MCS with an increasing threat for damaging wind. Development farther southwest into central KS along a convergent boundary remains uncertain, but will maintain a conditional slight risk for this area. ...Eastern Wyoming into western Nebraska... Deeper ascent with a shortwave trough now moving through northwest WY may contribute to additional thunderstorm development across eastern WY later this evening or tonight where modest instability and 40-50 kt effective bulk shear will support a risk for organized storms capable of isolated large hail and a few locally strong to damaging gusts. ..Dial.. 08/16/2019 Read more

MD 1751 CONCERNING SEVERE THUNDERSTORM WATCH 583... FOR SOUTHEAST SOUTH DAKOTA...SOUTHWEST MINNESOTA...NORTHWEST IOWA
Mesoscale Discussion 1751 NWS Storm Prediction Center Norman OK 0748 PM CDT Thu Aug 15 2019 Areas affected...southeast South Dakota...southwest Minnesota...northwest Iowa Concerning...Severe Thunderstorm Watch 583... Valid 160048Z - 160245Z The severe weather threat for Severe Thunderstorm Watch 583 continues. SUMMARY...Severe wind/hail remain possible with a line of storms in southeast South Dakota and southwest Minnesota. A local watch extension may be necessary. DISCUSSION...A line of storms continues moving east-southeast across eastern South Dakota and now into southwest Minnesota. The northern portion of the line has weakened as it encountered weaker instability. However, the southern portion of the line still has potential for severe hail/wind with better access to instability/shear (MLCAPE of 1000-1500 J/kg and effective bulk shear of 50-55 knots per mesoanalysis). Recent near severe gusts have been reported with 43 knots at Madison, SD and 1.5 inch hail was also reported near Madison. The southern portion of the line is showing potential to extend farther south with a cell now developing just west of Sioux Falls. These storms are moving out of the watch and a local extension is possible across portions of southwest Minnesota, southeast South Dakota, and northwest Iowa. ..Nauslar/Guyer.. 08/16/2019 ...Please see www.spc.noaa.gov for graphic product...

MD 1750 CONCERNING SEVERE THUNDERSTORM WATCH 584... FOR SOUTHEAST NEBRASKA...NORTHEAST KANSAS...AND NORTHWEST MISSOURI
Mesoscale Discussion 1750 NWS Storm Prediction Center Norman OK 0703 PM CDT Thu Aug 15 2019 Areas affected...southeast Nebraska...northeast Kansas...and northwest Missouri Concerning...Severe Thunderstorm Watch 584... Valid 160003Z - 160200Z The severe weather threat for Severe Thunderstorm Watch 584 continues. SUMMARY...Severe weather risk continues across WW 584. DISCUSSION...Storms that prompted the initial issuance of Severe Thunderstorm Watch 584 have moved southeast into northwestern Missouri, weakening with time. Meanwhile, new storm development has occurred on northern and western fringes of the watch -- and areas farther west across northwest Kansas that reside within Tornado Watch 585. While initial risk was primarily for large hail, with storms elevated above the remnant cold pool, storms developing west of the watch are more nearly surface based -- with all severe hazards possible. A few of these storms may affect western portions of WW 584, while otherwise, an increase in slightly elevated convection across WW 584 is expected to continue, as a low-level jet strengthens this evening. ..Goss.. 08/16/2019 ...Please see www.spc.noaa.gov for graphic product...

WW 583 SEVERE TSTM MN SD 152010Z - 160200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 583 NWS Storm Prediction Center Norman OK 310 PM CDT Thu Aug 15 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Far west-central Minnesota Central and eastern South Dakota * Effective this Thursday afternoon and evening from 310 PM until 900 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...A mix of discrete cells and clusters should intensify into early evening in central South Dakota, potentially evolving into a broader linear cluster that shifts east across eastern South Dakota into perhaps far western Minnesota. The severe thunderstorm watch area is approximately along and 75 statute miles north and south of a line from 10 miles northwest of Pierre SD to 30 miles east of Watertown SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 1749 CONCERNING SEVERE THUNDERSTORM WATCH 583... FOR EASTERN SOUTH DAKOTA AND VICINITY
Mesoscale Discussion 1749 NWS Storm Prediction Center Norman OK 0542 PM CDT Thu Aug 15 2019 Areas affected...eastern South Dakota and vicinity Concerning...Severe Thunderstorm Watch 583... Valid 152242Z - 160045Z The severe weather threat for Severe Thunderstorm Watch 583 continues. SUMMARY...The severe threat continues across eastern portions of WW583 in eastern South Dakota and vicinity. Damaging winds and large hail remain possible through 0200 UTC. DISCUSSION...A line of thunderstorms continues to move eastward across eastern South Dakota and recently produced a 66 MPH wind gust at a mesonet site in Day county. Recent radar trends from KABR show two areas where the rear inflow has strengthened in Clark and Day counties and could be foci for severe wind and a possible brief, weak tornado. Given the storm environment downstream of MLCAPE of 1000-1500 J/kg and effective bulk shear of 40-50 knots, the line of storms should continue moving eastward and maintain its intensity. Storm development and intensification on southern portion of the line may occur, especially since the instability remains favorable longer, with the hail threat being greater in this area. Even with the large-scale ascent associated with the shortwave trough moving over South Dakota, storms will begin to wane in southwest Minnesota/northwest Iowa without a low-level jet to help sustain development tonight. Storms may move outside of the watch later this evening before weakening, but a new watch is unlikely at this time. ..Nauslar/Guyer.. 08/15/2019 ...Please see www.spc.noaa.gov for graphic product...
