Areas affected...parts of northern to central IL

Concerning...Severe Thunderstorm Watch 534...

Valid 150352Z - 150515Z

The severe weather threat for Severe Thunderstorm Watch 534
continues.

SUMMARY...A renewed strong to severe wind threat may evolve
southeast from a thunderstorm cluster over the Quad Cities into
parts of central Illinois overnight. This threat may remain
relatively isolated.

DISCUSSION...While the primary MCV and bowing linear cluster has
spread over the Chicagoland area, renewed deep convection
intensified on the backside of the trailing outflow over the Quad
Cities. The southern portion of this renewed development that can
persist south of the earlier outflow will have the potential to
further intensify and yield a swath of strong to severe wind gusts.
This will be aided by the presence of moderate west-northwesterly
low to mid-level flow as sampled by the DVN VWP, and a lobe of
enhanced buoyancy extending east of the instability max over
northern MO. While most of this threat should be contained within WW
534 during the next couple hours, it may spread just south of the
watch within a confined corridor overnight.
