WW 30 SEVERE TSTM KS OK 072025Z - 080300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 30 NWS Storm Prediction Center Norman OK 225 PM CST Thu Mar 7 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Kansas Northern Oklahoma * Effective this Thursday afternoon and evening from 225 PM until 900 PM CST. * Primary threats include...

MD 0199 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF THE TX BIG COUNTRY/CONCHO VALLEY
Mesoscale Discussion 0199 NWS Storm Prediction Center Norman OK 0206 PM CST Thu Mar 07 2024 Areas affected...Parts of the TX Big Country/Concho Valley Concerning...Severe potential...Watch possible Valid 072006Z - 072200Z Probability of Watch Issuance...60 percent SUMMARY...The severe-thunderstorm threat is expected to increase later this afternoon. A couple of supercells will be possible, with a threat of large hail, isolated severe gusts, and possibly a tornado or two. DISCUSSION...Diurnal heating of an increasingly moist airmass is ongoing this afternoon, mainly to the south and west of a band of elevated convection extending from west-central to north-central TX. Steep midlevel lapse rates atop the increasing moisture are supporting MLCAPE approaching 1000 J/kg, though poor upper-level lapse rates within a cirrus plume are likely limiting the depth of stronger buoyancy. Strong mid/upper-level flow is supporting effective shear of 60+ kt across the region, more than sufficient for organized storms. The details of storm initiation and coverage remain somewhat uncertain, though continued heating and diminishing MLCINH will likely support isolated to widely scattered storm development along a diffuse dryline later this afternoon. Some increasing cumulus has also been noted near San Angelo, in the vicinity of an apparent outflow boundary, where surface winds are backed to more of an easterly direction. This boundary could serve as a focus for storm initiation as well, or else provide a favored corridor for storms that move in from the west late this afternoon or early this evening. With favorable shear in place, at least a couple supercells could develop by late afternoon, posing a threat of hail (potentially in the 1.5 to 2 inch diameter range) and localized severe gusts. Some tornado threat could also evolve, especially where surface winds are backed near the remnant outflow boundary. Watch issuance is possible by 4 PM CST if convective initiation appears imminent. ..Dean/Hart.. 03/07/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...SJT...LUB...MAF...

MD 0197 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTH CENTRAL OKLAHOMA TO SOUTHEAST KANSAS
Mesoscale Discussion 0197 NWS Storm Prediction Center Norman OK 0127 PM CST Thu Mar 07 2024 Areas affected...North central Oklahoma to southeast Kansas Concerning...Severe potential...Watch possible Valid 071927Z - 072200Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorm development is expected across north-central Oklahoma and southeast Kansas in the coming hours. These storms will likely pose a threat for large hail and damaging winds, and perhaps a tornado or two. Trends are being monitored for a possible watch issuance. DISCUSSION...Over the past several hours, gradually clearing skies across north-central OK and south-central KS have allowed temperatures to warm into the mid 60s to low 70s. Although diurnal mixing has scoured moisture to the south of the synoptic frontal zone (dewpoints have fallen into the mid to upper 40s), dewpoints remain in the mid 50s along the surface warm front and to the north of a differential heating/outflow boundary draped across northern OK. With steep mid-level lapse rates overspreading the region, MLCAPE is gradually increasing with further improvement possible amid a subtle influx of low-level moisture from northeast OK within the southeasterly flow regime. Thunderstorm initiation is probable in the coming hours in the vicinity of the surface low and/or along the differential heating boundary as ascent associated with a subtle mid-level perturbation overspreads the region (denoted by a cirrus plume currently over the TX Panhandle). Latest HRRR/WOFS guidance suggests this should occur during the 21-23 UTC time frame. Wind profiles will be favorable for supercells, and enhanced low-level helicity between the differential heating boundary and warm front may support a locally higher tornado threat across northern OK/south-central KS. Further downstream into southeast KS, the gradual erosion of the stratiform rain/cloud field casts uncertainty on destabilization, but a few robust storms will likely persist and pose a hail/wind threat this evening. Trends will continue to be monitored for watch issuance. ..Moore/Hart.. 03/07/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TSA...TOP...ICT...OUN...

MD 0198 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL AND WESTERN OKLAHOMA INTO NORTHWEST TEXAS
Mesoscale Discussion 0198 NWS Storm Prediction Center Norman OK 0130 PM CST Thu Mar 07 2024 Areas affected...Central and western Oklahoma into northwest Texas Concerning...Severe potential...Watch possible Valid 071930Z - 072130Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorm development is anticipated in the coming hours. These storms will initially pose a large hail threat before transitioning to primarily a severe wind threat during the evening hours. Watch issuance is probable. DISCUSSION...Surface observations over the past few hours have shown gradual moisture return into western OK ahead of a sharpening dryline/surface trough. Although this moisture is somewhat meager (low to mid 50 dewpoints), steep mid-level lapse rates continue to overspread the region amid a west/southwesterly mid-level flow regime. While MLCAPE remains very minimal at the moment, continued low-level moisture return should result in gradually improving buoyancy through the late afternoon and evening hours. Regardless, ascent associated with a subtle mid-level perturbation is overspreading the TX Panhandle with high-based cumulus development noted behind the dryline. This ascent is forecast to reach the warm sector across western OK/northwest TX in the coming hours, and recent HRRR/WOFS runs suggest initiation is likely during the 21-23 UTC period. Although convection may initially be anemic owing to the modest buoyancy, the severe threat should steadily increase heading into the evening hours with initially discrete cells posing a large hail risk across northwest TX/western OK before upscale growth favors an increasing wind threat further east into central OK. Watch issuance is probable in the coming hours as sufficient buoyancy becomes established to support severe convection. ..Moore/Hart.. 03/07/2024 ...Please see www.spc.noaa.gov for graphic product...
