Areas affected...southeastern Minnesota...far eastern
Iowa...northern Illinois...and southern Wisconsin

Concerning...Severe Thunderstorm Watch 34...35...

Valid 150221Z - 150345Z

The severe weather threat for Severe Thunderstorm Watch 34, 35
continues.

SUMMARY...Local risk for damaging wind gusts continues, and may
spread into parts of southern Wisconsin east of WW 34. This may
require new WW issuance.

DISCUSSION...Latest radar loop shows a band of generally weak
convection from a reflectivity perspective, moving northeastward
across parts of southern Minnesota and eastern Iowa, and into
northwestern Illinois. Despite the weak reflectivity structure, the
still-dry sub-cloud layer in tandem with very strong flow aloft
ahead of the advancing upper low suggests conditions supportive of
locally strong wind gusts. Thus -- expect local potential for
damaging winds to continue over the next couple of hours across
portions of WW 34 and 35, and eventually portions of southern
Wisconsin outside of these watches. A new WW issuance may be needed
soon, to highlight this potential into southeastern Wisconsin.
