Mesoscale Discussion 0601 NWS Storm Prediction Center Norman OK 0857 PM CDT Sat Apr 29 2017 Areas affected...Central/South Central TX Concerning...Severe Thunderstorm Watch 177... Valid 300157Z - 300300Z The severe weather threat for Severe Thunderstorm Watch 177 continues. SUMMARY...Isolated severe wind gusts/hail remain possible with thunderstorms across WW177, and adjacent counties just south of the watch, this evening. DISCUSSION...Frontal convection has struggled to organize across south central TX this evening. Much of the deepest convection is located along the cool side of the boundary and remains rather weak, though recent development across Wilson/Atascosa Counties appears to be rooted near the surface along the immediate wind shift. Latest MRMS data suggests large hail is occurring with the southern-most thunderstorms over Atascosa County. 00z sounding from CRP exhibits significant CINH and it appears this activity may be the southern extent of meaningful thunderstorms tonight. ..Darrow.. 04/30/2017 ...Please see www.spc.noaa.gov for graphic product...
