Mesoscale Discussion 0603 NWS Storm Prediction Center Norman OK 1137 PM CDT Sat Apr 29 2017 Areas affected...Northeast TX to Central AR Concerning...Severe Thunderstorm Watch 178... Valid 300437Z - 300530Z The severe weather threat for Severe Thunderstorm Watch 178 continues. SUMMARY...Severe wind gusts and hail remain possible with thunderstorms across WW178. DISCUSSION...Widespread convection continues across western/northern AR late this evening reflecting the southern-most extent of expansive, long-lived precip event that is centered over MO. Isolated hail and gusty winds continue with the strongest storms that are embedded along the southern flank of this MCS. Over the next few hours thunderstorms should increase along the cold front as it progresses into the lower MS Valley region as large-scale forcing for ascent appears to be approaching the I-35 corridor, per deep convection developing from portions of the Hill Country into northwest TX. Convection is gradually deepening across southeast TX and immediately behind the front over northeast TX...possibly in response to this large-scale forcing. For these reasons it appears storms should increase in areal coverage after midnight across WW178. ..Darrow.. 04/30/2017 ...Please see www.spc.noaa.gov for graphic product...
