Areas affected...portions of central IA
Concerning...Severe Thunderstorm Watch 584...
Valid 100959Z - 101130Z
The severe weather threat for Severe Thunderstorm Watch 584
continues.
SUMMARY...Isolated strong to severe wind gusts remain possible
across central Iowa.
DISCUSSION...A cluster of storms will continue to track northeast
across central Iowa this morning. Overall radar presentation has
become somewhat disorganized, but a corridor of 60-70 kt velocity
signatures aloft are still noted to the west of the Des Moines
vicinity. Instability decreases gradually with northeast extent, and
stronger effective shear magnitudes remain displaced to the north.
While severe gusts are possible over the next couple of hours, the
expectation is that a gradual weakening trend will continue as
convection develops northeast.
