Concerning...Severe Thunderstorm Watch 606...

Valid 210141Z - 210245Z

The severe weather threat for Severe Thunderstorm Watch 606
continues.

SUMMARY...The risk of strong to severe downbursts will continue for
another hour or two.

DISCUSSION...The latest radar data from KDGX depicts
outflow-dominant thunderstorms, with new cell development along
outflow boundaries. The JAN 00Z sounding sampled steep low-level
lapse rates and moderate-strong surface-based buoyancy, and despite
weak deep-layer flow/shear, this environment remains favorable for
strong to severe downbursts. Given the overall lack of convective
organization, the severe risk should gradually diminish over the
next couple hours as the boundary layer nocturnally cools.
