WW 263 SEVERE TSTM ND SD 200010Z - 200400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 263 NWS Storm Prediction Center Norman OK 710 PM CDT Sun May 19 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern North Dakota Northeast South Dakota * Effective this Sunday evening from 710 PM until 1100 PM CDT. * Primary threats include... Scattered large hail events to 1.5 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Scattered strong to severe thunderstorms will potentially be capable of 60-70 mph gusts and large hail 1 to 1.5 inches in diameter through the evening hours. The severe risk is forecast to diminish by late evening. The severe thunderstorm watch area is approximately along and 50 statute miles east and west of a line from 75 miles north of Mobridge SD to 120 miles southeast of Mobridge SD. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0845 CONCERNING SEVERE THUNDERSTORM WATCH 260...262... FOR SOUTHEASTERN KANSAS
Mesoscale Discussion 0845 NWS Storm Prediction Center Norman OK 0815 PM CDT Sun May 19 2024 Areas affected...southeastern Kansas Concerning...Severe Thunderstorm Watch 260...262... Valid 200115Z - 200315Z The severe weather threat for Severe Thunderstorm Watch 260, 262 continues. SUMMARY...Stronger surface gusts, perhaps occasionally exceeding 70 mph, may be maintained with an evolving cluster of storms northeast and east of Wichita toward the Joplin MO/Bartlesville OK vicinities through 10-11 PM CDT. DISCUSSION...Trailing one still well-defined MCV now migrating eastward along the I-70 corridor near Manhattan, a second MCV is becoming better-defined along intersecting outflow boundaries to the north of Wichita. Associated with this evolution, measured gusts to 75 kt were recorded in Hutchinson at 0039Z. Although inflow into the convective system may become less unstable due to somewhat drier low-level air across much of eastern Kansas/Oklahoma, strong to severe gusts may continue at least another couple of hours to the southwest/south of the evolving southern MCV. ..Kerr.. 05/20/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0844 CONCERNING SEVERE THUNDERSTORM WATCH 260... FOR PARTS OF WEST CENTRAL INTO NORTH CENTRAL OKLAHOMA
Mesoscale Discussion 0844 NWS Storm Prediction Center Norman OK 0748 PM CDT Sun May 19 2024 Areas affected...parts of west central into north central Oklahoma Concerning...Severe Thunderstorm Watch 260... Valid 200048Z - 200245Z The severe weather threat for Severe Thunderstorm Watch 260 continues. SUMMARY...A long-lived isolated supercell storm may be maintained at least another couple of hours, possibly impacting at least northern portions of the Greater Oklahoma City area by 10-11 PM CDT, with a risk for large hail in excess of 2 inches, strong, damaging wind gusts and perhaps a continuing risk for a tornado. DISCUSSION...Embedded within southwesterly deep-layer mean flow on the order of 30-35 kt, an isolated intense supercell has been slowly propagating eastward, away from the initiating dryline, to the north of the Clinton-Sherman vicinity. Low-level hodographs have been enlarging some, and a more notable increase in low-level shear is forecast through 04-06Z, along a strengthening southerly 850 mb jet (in excess of 50 kt) from northwest Texas toward the Medicine Loge KS area. However, with the onset of diurnal boundary-layer cooling, inhibition across and east of the dryline is already in the process of increasing, and lower/mid-tropospheric warming forecast across much of Oklahoma this evening will contribute further to this. Even so, given the favorable shear beneath a seasonably strong westerly mid/upper jet nosing into the south central Great Plains, and the strong potential instability eastward into the I-35 corridor, it is possible that the ongoing supercell may be maintained another couple of hours, eastward through northern portions of the Greater Oklahoma City area. ..Kerr.. 05/20/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0842 CONCERNING SEVERE THUNDERSTORM WATCH 260...262... FOR SOUTH CENTRAL/SOUTHEASTERN KANSAS AND NORTH CENTRAL/NORTHEASTERN OKLAHOMA
Mesoscale Discussion 0842 NWS Storm Prediction Center Norman OK 0700 PM CDT Sun May 19 2024 Areas affected...south central/southeastern Kansas and north central/northeastern Oklahoma Concerning...Severe Thunderstorm Watch 260...262... Valid 200000Z - 200230Z The severe weather threat for Severe Thunderstorm Watch 260, 262 continues. SUMMARY...Organizing convective clusters accompanied by potentially strong, damaging wind gusts may increasingly impact areas east of the Interstate 35 corridor of southeastern Kansas and northeastern Oklahoma after 10 PM. Trends are being monitored for an additional severe weather watch across northeastern Oklahoma. DISCUSSION...Convective evolution into late evening remains somewhat unclear. As a low amplitude mid-level short wave progresses across central Kansas toward the lower Missouri Valley, mid-level warming is forecast across much of Oklahoma. Coupled with the onset of boundary-layer cooling, this will contribute to increasing inhibition, with the nose of a strengthening southerly low-level jet (50+ kt around 850 mb) becoming focused over southwestern/south central Kansas near Medicine Loge. However, a corridor of higher moisture content air remains focused east of the dryline through areas near/just east of the Interstate 35 corridor. Supported by inflow of this air, with CAPE up to around 3000 J/kg, ongoing convection may continue to grow upscale and organize further during the next few hours, and potentially begin to impact portions of southeastern Kansas/northeastern Oklahoma as early as 03-05Z. ..Kerr/Smith.. 05/20/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0843 CONCERNING SEVERE THUNDERSTORM WATCH 261... FOR NORTHWEST KS
Mesoscale Discussion 0843 NWS Storm Prediction Center Norman OK 0713 PM CDT Sun May 19 2024 Areas affected...Northwest KS Concerning...Severe Thunderstorm Watch 261... Valid 200013Z - 200145Z The severe weather threat for Severe Thunderstorm Watch 261 continues. SUMMARY...Large hail of 1 to 1.75 inches in diameter and localized strong gusts from 45 to 60 mph will be possible for a couple more hours across northwest Kansas. This activity should diminish after dusk. DISCUSSION...With a multitude of surface boundaries that collided across parts of northwest Kansas, a few severe thunderstorms have developed with reported hail up to 2 inches in diameter thus far. This activity will likely remain nearly stationary as subsidence behind the intense MCS over central KS suggests convection will struggle to move east from northwest KS. As such, the severe threat will persist through about dusk and likely diminish as MLCIN nocturnally increases. ..Grams.. 05/20/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 260 SEVERE TSTM KS OK TX 191935Z - 200300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 260 NWS Storm Prediction Center Norman OK 235 PM CDT Sun May 19 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western and Central Kansas Northwestern Oklahoma Northeastern Texas Panhandle * Effective this Sunday afternoon and evening from 235 PM until 1000 PM CDT. ...THIS IS A PARTICULARLY DANGEROUS SITUATION... * Primary threats include... Widespread damaging winds expected with scattered significant gusts to 90 mph likely Widespread large hail expected with scattered very large hail events to 4 inches in diameter likely A few tornadoes possible SUMMARY...Numerous severe thunderstorms are expected to develop and track rapidly eastward across the watch area through the afternoon evening. Supercells capable of giant hail, damaging winds, and isolated tornadoes will be the main threat early. Storms will organize into multiple fast-moving bowing lines through the evening with a risk of widespread damaging winds.
