Mesoscale Discussion 0672 NWS Storm Prediction Center Norman OK 0139 AM CDT Tue May 07 2024 Areas affected...Eastern Oklahoma...Northwestern Arkansas...Southwest Missouri Concerning...Tornado Watch 192...193...194... Valid 070639Z - 070845Z The severe weather threat for Tornado Watch 192, 193, 194 continues. SUMMARY...A tornado, wind-damage and isolated large-hail threat will continue from eastern Oklahoma into northwest Arkansas and southwest Missouri over the next several hours. DISCUSSION...The latest hi-resolution radar imagery from Tulsa shows the southern half of a linear MCS, located from southwest Missouri southwestward into east-central Oklahoma. The MCS is located near an axis of instability, where the RAP is analyzing MLCAPE in the 1500 to 2500 J/kg range. In addition, RAP forecast soundings along this corridor are impressive, with 0-6 km shear near 60 knots, and 0-3 km storm-relative helicity in the 500 to 600 ms/s2 range. This will continue to support a tornado threat with rotating cells embedded in the line. Wind damage will also be likely along the leading edge of the MCS, especially with the parts of the line that obtain bowing structure. Forecast soundings near the storms also have 700-500 mb lapse rates around 8 C/km, which will support an isolated large-hail threat. The line is expected to continue to be severe over the next couple of hours, as it moves through the Ozarks. ..Broyles.. 05/07/2024 ...Please see www.spc.noaa.gov for graphic product...
