Areas affected...Western to south-central IA

Concerning...Severe Thunderstorm Watch 565...

Valid 300645Z - 300745Z

The severe weather threat for Severe Thunderstorm Watch 565
continues.

SUMMARY...Strong to localized severe gusts may spread east-southeast
of WW 565 with approach of a short-line segment over
west-central/southwest Iowa. An extension of the watch in area has
been coordinated.

DISCUSSION...A short-line segment which produced several measured
severe wind gusts of 60-70 mph closer to the MO Valley, has appeared
to weaken slightly over the past hour. Still, it has produced a few
measured wind gusts of 50-60 mph, and similar intensity may persist
east-southeastward as the segment approaches the I-35 corridor in
central/south-central IA. Longevity of the strong to severe wind
threat is uncertain as the line segment and associated MCV progress
towards eastern IA. The presence of the MLCAPE gradient should
maintain stronger gust potential in the near-term, but relatively
weak low-level flow (with the low-level jet well to the southwest in
KS) may yield a gradual diminishing trend towards dawn.
