Areas affected...Extreme eastern IA into northern IL and extreme
southern WI

Concerning...Severe Thunderstorm Watch 361...

Valid 040024Z - 040200Z

The severe weather threat for Severe Thunderstorm Watch 361
continues.

SUMMARY...Threat for severe/damaging wind and line-embedded
tornadoes will spread northeastward this evening.

DISCUSSION...A storm cluster with embedded circulations remains
intense early this evening near/south of Davenport, IA. Deep-layer
shear vectors remain favorably orthogonal with this line segment,
with stronger cores aloft indicating the presence of embedded
supercells within this cluster. Favorably moist and sufficiently
unstable downstream conditions favor maintenance of this system into
a larger portion of northwest IL. A wind gust of 81 mph was recorded
earlier in Burlington, IA, and wind gusts of 60-80 mph remain
possible with this intense storm cluster. Low-level flow/shear is
strengthening ahead of the system (as noted on the KILX VWP), and
line-embedded tornadoes will continue to be possible, given the
presence of embedded supercell structures.=20=20

The severe threat may eventually spread east of WW 361, and local
expansion of the watch will continue to be possible with time this
evening.
