Mesoscale Discussion 1205 NWS Storm Prediction Center Norman OK 1024 PM CDT Fri Jun 30 2017 Areas affected...Northwest TX...OK...Northwest AR Concerning...Severe Thunderstorm Watch 386... Valid 010324Z - 010430Z The severe weather threat for Severe Thunderstorm Watch 386 continues. SUMMARY...Scattered thunderstorms will persist across the southern Plains into the early morning hours; however, only isolated severe is expected with this activity. DISCUSSION...Low-level warm advection is focused across the TX South Plains this evening as LLJ is gradually strengthening across this region. This appears to be partly responsible for renewed convective development in the vicinity of Stonewall County TX. Additional convection is beginning to strengthen across the southeast TX Panhandle along an ill-defined outflow-reinforced synoptic front. Hail may be noted with this activity across the high plains due to steeper lapse rate environment along the southern fringe of stronger northwestely mid-level flow. Considerable convective overturning across OK has stabilized much of the state and severe threat appears to be waning. Although isolated damaging wind gust or hail may be noted with convection near the Red River, new WW is not expected at this time. ..Darrow.. 07/01/2017 ...Please see www.spc.noaa.gov for graphic product...
