Day 1 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 1142 AM CDT Fri Apr 26 2024 Valid 261630Z - 271200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING FROM EASTERN NEBRASKA/WESTERN IOWA SOUTHWARD TO EASTERN OKLAHOMA AND NORTHEAST TEXAS... CORRECTED FOR WEB GRAPHICS ERROR ...SUMMARY... A few tornadoes, including a couple of strong tornadoes, isolated very large hail (greater than 2 inch diameter) and isolated wind damage will be possible, mainly this afternoon/evening from northeast Kansas/southeast Nebraska into western Missouri, eastern Oklahoma, western Arkansas, and northeast Texas. ...NE/IA/MO/KS... Water vapor loop shows a strong shortwave trough rotating across KS/NE. A deep surface low is analyzed ahead of this trough over central NE, with a dryline extending southward into central KS. A corridor of ample low-level moisture is present ahead of the dryline over southeast NE/northeast KS, where daytime heating will lead to moderate MLCAPE values and rapid thunderstorm development by mid-afternoon. Backed low-level winds and favorable shear profiles will promote supercells in the bent-back region of the low, with very large hail and tornadoes possible. These storms will progress eastward into western IA and northwest MO through the early evening. A strong tornado or two is possible in this region. ...OK/MO/AR... A large nocturnal MCS that affected much of OK has quickly weakened and departed, with rapid northward return of low-level moisture occurring in the wake of the system. By mid-afternoon, mid-upper 60s dewpoints are expected along the dryline over east-central OK. Forecast soundings show very steep mid-level lapse rates and favorable shear profiles to promote discrete supercells capable of all severe hazards, including very large hail and strong tornadoes. Storms will track northeastward into southwest MO and northwest AR this evening. CAM guidance varies on coverage of storms, but parameters appear quite strong and warrant an upgrade to ENH given the conditional risk of significant severe weather. ...Northeast TX... A third area of significant risk of severe storms lies across parts of northeast and east-central TX today. A cluster of severe/supercell storms has formed this morning to the west of Waco, TX. These storms are expected to increase in coverage through the afternoon and develop eastward across much of northeast TX. Forecast soundings show a very moist and unstable environment, with sufficient low-level and deep-layer shear for persistent supercell structures and risks of a few tornadoes and very large hail. Given the number of storms and the favorable environment, have also upgraded this narrow corridor to ENH. ..Hart.. 04/26/2024 Read more

MD 0524 CONCERNING TORNADO WATCH 138... FOR EASTERN OK TO SOUTHWEST MO/WESTERN AR
Mesoscale Discussion 0524 NWS Storm Prediction Center Norman OK 0735 AM CDT Fri Apr 26 2024 Areas affected...Eastern OK to southwest MO/western AR Concerning...Tornado Watch 138... Valid 261235Z - 261430Z The severe weather threat for Tornado Watch 138 continues. SUMMARY...Severe thunderstorms including the potential for primarily damaging winds and a couple tornadoes continues across eastern Oklahoma, and may develop into far western Arkansas and possibly southwest Missouri. Tornado Watch 138 continues for eastern Oklahoma, and downstream Arkansas/southwest Missouri areas are being monitored for possible but uncertain Watch issuance in the short term. DISCUSSION...A well-organized squall line with LEWP/northern-peripheral bowing characteristics continues across eastern Oklahoma, with bow-related northeastward storm motions around 50 kt. The most intense portion of the squall line and greatest short-term severe risk should be focused where the convective line intercepts the warm front (and just a bit north thereof) in the general vicinity of I-40 in far eastern Oklahoma into west/northwest Arkansas. Farther north, the severe-potential longevity of the surging bowing portion of the line is a bit more uncertain with northward extent, given that the bowing line will gradually encounter an increasingly more stable boundary layer (0.5 km AGL deep per 12z Springfield MO observed sounding). ..Guyer.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product...
