MD 0519 CONCERNING TORNADO WATCH 133... FOR NORTHERN KANSAS/SOUTHERN NEBRASKAMesoscale Discussion 0519 NWS Storm Prediction Center Norman OK 0935 PM CDT Thu Apr 25 2024 Areas affected...northern Kansas/southern Nebraska Concerning...Tornado Watch 133... Valid 260235Z - 260330Z The severe weather threat for Tornado Watch 133 continues. SUMMARY...Tornado risk has diminished, but hail risk will continue across portions of the WW area and eastward into central Nebraska/north-central Kansas. New WW will be proposed. DISCUSSION...Latest radar shows that storms continue to evolve into a more clustered mode, and mainly to the north of the surface front as a low-level jet continues to increase. Resulting warm advection atop the surface front will continue to support thunderstorm development/maintenance, given moderate elevated CAPE indicated across the area. While tornado threat should continue to decrease, potential for hail in the 1" to 1.75" range over the next few hours supports consideration of severe thunderstorm watch issuance, with the tornado watch set to expire at 26/03Z. ..Goss.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0518 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF WEST AND NORTHWEST TEXAS
Mesoscale Discussion 0518 NWS Storm Prediction Center Norman OK 0919 PM CDT Thu Apr 25 2024 Areas affected...portions of west and northwest Texas Concerning...Severe potential...Watch likely Valid 260219Z - 260345Z Probability of Watch Issuance...95 percent SUMMARY...Severe threat is increasing through the evening/overnight. A watch will likely be needed soon. DISCUSSION...Thunderstorm development has been noted near the Permian Basin across southwestern Texas. Expectations are for further development to continue through the next few hours, with upscale growth into a potential MCS overnight. Given the potential for upscale growth, the main threats will likely be damaging winds and hail. A tornado or two will be possible, given favorable deep-layer shear. A watch will likely be needed within the hour. ..Thornton/Edwards.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...OUN...SJT...LUB...MAF...

MD 0516 CONCERNING TORNADO WATCH 134... FOR NORTHERN TEXAS PANHANDLE...CENTRAL OKLAHOMA PANHANDLE...AND SOUTHWESTERN KANSAS
Mesoscale Discussion 0516 NWS Storm Prediction Center Norman OK 0742 PM CDT Thu Apr 25 2024 Areas affected...northern Texas Panhandle...central Oklahoma Panhandle...and southwestern Kansas Concerning...Tornado Watch 134... Valid 260042Z - 260245Z The severe weather threat for Tornado Watch 134 continues. SUMMARY...Severe threat continues across WW134. Additional thunderstorm development possible over the next couple of hours. DISCUSSION...Visible satellite imagery across the Texas/Oklahoma Panhandles continues to show areas of towering cumulus clustered along the dryline. Thus far, attempts at initiation have been unsuccessful. The 00z RAOB from AMA indicates MLCIN has eroded amid steep lapse rates throughout the profile. Given the increase expected in the low-level jet through the next couple of hours and additional synoptic forcing for ascent, further scattered thunderstorm development will be possible. Recent CAM guidance supports this notion, though there are difference in timing/location of initiation within this region. Surface objective analysis indicates around 2500-3000 J/kg MLCAPE with deep layer shear at 50-55 kts. Given initially modest forcing and south-southwesterly deep layer flow, storms will initiate along the dryline before moving north eastward with the initial threat of large hail and damaging winds. Any cells that maintain strength through the evening will see an increasing threat for tornadoes as the low-level jet increases enlarging hodographs and increasing low-level shear. ..Thornton/Edwards.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product...
