Areas affected...central to northeast Iowa

Concerning...Severe Thunderstorm Watch 437...

Valid 022053Z - 022230Z

The severe weather threat for Severe Thunderstorm Watch 437
continues.

SUMMARY...A cluster of supercells across northeast Iowa will
continue this afternoon and into the evening.

DISCUSSION...Scattered large hail and wind gusts have been reported
across northeast Iowa this afternoon with a cluster of supercells.
Additional development continues on the southwest flank where
dewpoints are in the mid 70s with temperatures near 90 F, yielding
MLCAPE near 3000 J/kg per SPC mesoanalysis. Mid-level flow around 40
to 45 knots (sampled by the KDMX VWP) is supporting supercell
structures and will continue to assist in updraft rotation this
afternoon and evening. The orientation of the storms and updraft
collisions may limit the overall severe threat somewhat. However,
the environment will continue to support large hail and severe wind
gusts late this afternoon and into the evening.
