SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1223 AM CDT Fri Aug 30 2019 Valid 301200Z - 311200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN AND CENTRAL PLAINS...HIGH PLAINS AND OHIO VALLEY... ...SUMMARY... Scattered storms, some producing severe wind gusts, are possible over southern Kansas into Oklahoma and the Texas Panhandle today. Storms with marginally severe wind gusts will also be possible in the Ohio Valley. Other storms capable of mainly hail are expected near the Front Range. ...Southern and Central Plains... West to northwest mid-level flow will be in place today across the central U.S. as a shortwave trough moves southeastward into the Ozarks. An MCS associated with marginally severe wind gusts should be located in eastern Oklahoma and northwestern Arkansas at the beginning of the period. At the surface, a cold front is forecast to move southward into the central Oklahoma and the Texas Panhandle. Along and south of the front, surface dewpoints in the upper 60s and lower 70s F should result in a pocket of moderate instability by afternoon. This combined with increasing low-level convergence along the front will result in isolated to scattered thunderstorm development. In spite of the instability in place, NAM forecast soundings have 0-6 km shear values across Oklahoma and the Texas Panhandle generally less than 25 kt. This should keep any severe threat isolated. The stronger multicells may have potential for marginally severe wind gusts and hail. ...Ohio Valley... A shortwave trough will move across the mid Mississippi Valley today. At the surface, a cold front will advance southward into the Ohio Valley. Surface dewpoints in the upper 60s F will likely result in a pocket of moderate instability along and just south of the front by afternoon. Thunderstorms are forecast to initiate along the front in southern Illinois and southern Indiana during the mid to late afternoon as the shortwave trough approaches. This activity should spread eastward into southern Ohio and northern Kentucky by early evening. Steep low-level lapse rates combined with the moderate instability may be enough for marginally severe wind gusts with the stronger multicells. ...High Plains... West northwest mid-level flow will be in place across the central High Plains today. At the surface, upslope easterly flow will push low-level moisture into the foothills. As surface temperatures warm, destabilization will result in isolated thunderstorm development in the higher terrain. This convection is forecast to move southeastward into the eastern Plains of Colorado. Although moderate deep-layer shear should be in place, instability should be weak enough to keep any hail threat marginal. ..Broyles/Squitieri.. 08/30/2019 Read more

Mesoscale Discussion 1896 NWS Storm Prediction Center Norman OK 1147 PM CDT Thu Aug 29 2019 Areas affected...eastern Kansas and extreme northeast Oklahoma Concerning...Severe Thunderstorm Watch 628... Valid 300447Z - 300615Z The severe weather threat for Severe Thunderstorm Watch 628 continues. SUMMARY...Damaging wind will remain likely across eastern Kansas next several hours. Severe threat is expected to increase across northeast OK by 06-07Z. DISCUSSION...A nearly solid line of storms have evolved along outflow boundary from northeast KS to south central KS near Hutchinson. This line is moving southeast around 40 kt, while farther east an outflow boundary continues to move westward through northeast KS. These boundaries will soon merge over northeast KS including Pottawatomie and Wabaunsee counties. The warm sector remains very unstable with high precipitable water and good downdraft potential. Storms may briefly intensify further during the merger, but should subsequently begin to turn more decidedly south southeast. Based on motion of the southwestern flank of the line (around 40 kt), the severe threat should increase across northeast OK by 0630Z which will probably necessitate a WW for the Tulsa CWA. ..Dial.. 08/30/2019 ...Please see www.spc.noaa.gov for graphic product...

MD 1895 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTH CENTRAL OKLAHOMA
Mesoscale Discussion 1895 NWS Storm Prediction Center Norman OK 1129 PM CDT Thu Aug 29 2019 Areas affected...north central Oklahoma Concerning...Severe potential...Watch unlikely Valid 300429Z - 300600Z Probability of Watch Issuance...20 percent SUMMARY...Storms are expected to move into north central Oklahoma by 05Z, posing a risk for mainly isolated strong to damaging wind gusts and hail. DISCUSSION...Small cluster of storms persists over extreme southern KS moving southeast at 20-25 kt and is approaching the OK border. VWP data from Vance show a 40 kt southerly low-level jet which is augmenting convergence along the gust front, and this may help to maintain the storms into northern OK into the early morning hours. The atmosphere remains strongly unstable across northern OK. However convective inhibition is increasing substantially, and the storms have moved south of the stronger winds aloft with weak vertical shear. These factors should limit storm organization as activity develops south, but given degree of instability, a few instances of locally strong to damaging wind gusts and hail will be possible. ..Dial/Goss.. 08/30/2019 ...Please see www.spc.noaa.gov for graphic product...

SUMMARY...Primary severe threat for remainder of WW 627 will exist across extreme northeast KS into extreme northwest MO through about 0430Z. DISCUSSION...An expansive outflow boundary from west central MO into northeast KS continues to surge west. The strongest storms are now developing over northeast KS along the intersection of the westward-advancing outflow boundary and a southward-moving east-west oriented outflow boundary. The atmosphere has been overturned and the boundary layer stabilized east of the boundary across much of MO including most of the remainder of WW 627, suggesting limited severe potential after 0430Z. ..Dial.. 08/30/2019 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1893 NWS Storm Prediction Center Norman OK 0952 PM CDT Thu Aug 29 2019 Areas affected...Much of central into eastern Kansas Concerning...Severe Thunderstorm Watch 626...628... Valid 300252Z - 300415Z The severe weather threat for Severe Thunderstorm Watch 626, 628 continues. SUMMARY...Upscale growth of convection will continue over the next several hours, with damaging winds likely continuing overnight. DISCUSSION...Smaller linear segments of intense multicellular convection have been congealing over the past couple of hours due to cold pool mergers, and increased low-level ascent at the terminus of a developing LLJ. Though the boundary layer has recently begun to decouple, stabilization is expected to be gradual given the relatively deep moisture in place. Ample buoyancy, with up to 4000 J/kg MUCAPE noted across much of the discussion area, will continue to fuel vigorous updrafts. Meanwhile strong low-level shear, provided by the the developing LLJ, will mitigate cold pools from undercutting convection to a degree, suggesting that potentially long-lived MCS structures may be realized. As such, damaging wind gusts are expected to accompany the aforementioned linear segments for several more hours. ..Squitieri/Goss.. 08/30/2019 ...Please see www.spc.noaa.gov for graphic product...

WW 626 SEVERE TSTM KS NE 292020Z - 300300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 626 NWS Storm Prediction Center Norman OK 320 PM CDT Thu Aug 29 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest and north central Kansas Southwest and south central Nebraska * Effective this Thursday afternoon and evening from 320 PM until 1000 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely A tornado or two possible SUMMARY...Thunderstorm development is expected by 4-5pm CDT from northwest Kansas into southwest Nebraska, and storms will spread east-southeastward through late evening. The initial storms could be supercells with very large hail, and there will also be some potential for a tornado or two with storms developing on the surface boundary across northwest Kansas and southwest Nebraska. Thereafter, storm mergers and upscale growth will support an increasing threat for damaging winds. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 55 miles west southwest of Mccook NE to 55 miles south southeast of Kearney NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 600. Mean storm motion vector 29020. ...Thompson Read more
