   Areas affected...far southeast IA/northeast MO to central IL

   Concerning...Severe Thunderstorm Watch 577...

   Valid 311030Z - 311230Z

   The severe weather threat for Severe Thunderstorm Watch 577
   continues.

   SUMMARY...A threat for strong to isolated severe gusts from 55-70
   mph should spread east-southeast of WW 577 into central Illinois. An
   additional severe thunderstorm watch is being considered.

   DISCUSSION...A cluster of strong to locally severe storms will
   likely progress east-southeast of WW 577, as it moves from the
   IA/MO/IL border area into central IL. Measured ASOS/AWOS gusts thus
   far have been up to 63 mph in Ottumwa, IA, with a personal weather
   station recently measuring 67 mph in far southeast IA. Despite the
   relatively short nature of the cluster's embedded line segment, the
   cold IR temps suggest that deep convective cores should persist
   along the MLCAPE gradient. While most gusts will probably remain
   sub-severe, a sufficient threat for severe gusts to around 70 mph
   should continue on an isolated basis through mid-morning.
