Areas affected...Parts of eastern IA...northeast MO...western IL

Concerning...Severe Thunderstorm Watch 361...

Valid 032314Z - 040045Z

The severe weather threat for Severe Thunderstorm Watch 361
continues.

SUMMARY...The threat for damaging wind and possibly a tornado will
spread northeastward this evening.

DISCUSSION...A QLCS has evolved across southeast IA into northeast
MO, and will continue spreading northeastward into a moist and
moderately unstable environment. A small bowing segment has evolved
within the northern portion of the QLCS across southeast IA, where
the orientation of the line has become more orthogonal to the
deep-layer shear vectors. This section of the line may pose a
locally greater threat of damaging wind through early evening as it
moves into northwest IL. Low-level shear (as depicted on the KDVN
VWP) is also sufficient to support some potential for a
line-embedded tornado. 

Farther south, the environment remains favorable along the southern
portion of the QLCS, and a threat for damaging wind and possibly a
brief tornado will eventually spread into west-central IL. Isolated
hail will also be possible with the stronger embedded cells.
