   The severe weather threat for Severe Thunderstorm Watch 293
   continues.

   SUMMARY...The threat for damaging winds and severe hail will
   continue for the next 1-2 hours for WW 293. The greatest near-term
   risk will likely reside across northeast Iowa.

   DISCUSSION...A convective line continues to push eastward across
   southeast MN and northern/northeast IA. So far, wind reports have
   generally been sub-severe, but radar imagery from KMPX and KARX
   suggest pockets of damaging wind remain possible as cold pool
   organization continues. 0-3 km bulk shear in this region remains
   nearly orthogonal to the line with magnitudes between 20-30 knots,
   further supporting the idea of at least an isolated damaging wind
   threat. 

   Although the line's eastward motion has phased well with the
   eastward progression of the surface low and viable warm sector,
   remnant stable outflow to the east across southern WI/northern IL
   may hinder storm intensity to some degree - especially north of an
   effective warm frontal boundary noted in recent surface obs. South
   of this boundary, the higher theta-e air mass should provide enough
   better instability to maintain storm intensity and the wind/hail
   threat into the evening hours.
