Mesoscale Discussion 0602 NWS Storm Prediction Center Norman OK 0938 PM CDT Sat Apr 29 2017 Areas affected...Arklatex Concerning...Severe potential...Watch likely Valid 300238Z - 300345Z Probability of Watch Issuance...80 percent SUMMARY...Severe thunderstorm watch will likely be issued by 03z across much of the Arklatex region. DISCUSSION...Surface front is progressing steadily east across northeast TX and will soon exit Tornado Watch 175. Surface front remains convectively active with the strongest thunderstorms located near the intersection of a remnant outflow boundary and the cold front over eastern Wood County. As this outflow boundary weakens, moisture/instability will return north across the Arklatex enhancing the likelihood for continued frontal convection into the early morning hours. While tornadoes can not be ruled out, it appears a linear squall line along the front will be the dominant storm type. For these reasons current thinking is a severe thunderstorm watch is warranted. ..Darrow/Thompson.. 04/30/2017 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LZK...SHV...
