Mesoscale Discussion 0600 NWS Storm Prediction Center Norman OK 0734 PM CDT Sat Apr 29 2017 Areas affected...Northeast TX Concerning...Tornado Watch 175... Valid 300034Z - 300130Z The severe weather threat for Tornado Watch 175 continues. SUMMARY...Tornado threat continues with pre frontal supercells. Otherwise, large hail and damaging winds are possible with forced squall line. DISCUSSION...Remnants of westward moving outflow, from compact long-lived MCS that has advanced into AR, has oriented itself from near GGG to northwest of TYR. Several supercells evolved in proximity to this boundary which appears to have aided a few notable tornadoes. Over the last half hour or so, linear convection along the cold front has progressed into this activity and multiple storm mergers are resulting in a complex frontal cluster from Hopkins County to northwest Henderson County. With time supercell characteristics may gradually become diffuse, though updrafts encountering the remnant outflow continue to have the greater tornado threat. Otherwise, hail/wind should be noted with with the stronger forced convection. ..Darrow.. 04/30/2017 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SHV...FWD...OUN...
