SPC Mesoscale Discussion: Severe Thunderstorm Watch 579…

| August 13, 2019 @ 5:09 pm

SUMMARY…The severe threat continues across WW 579.

DISCUSSION…Scattered strong to severe thunderstorms continue across mainly northern and central portions of ongoing WW 579 at this time. These storms are loosely organized and in a marginally strong shear environment, though strong instability (3500-5000 J/kg MUCAPE) continues to support occasional wind-damage-producing downbursts with mostly outflow-dominant storms. Observations and short-term model guidance suggests that these storms should continue to gradually grow upscale over the next few hours, with the severe threat tapering off from north to south as overturning and maturing cold-pool processes continue.
