Areas affected...Northeast Kansas...Southeast Nebraska...Far
Southwest Iowa...Northwest Missouri

Concerning...Tornado Watch 228...

Valid 240905Z - 241100Z

The severe weather threat for Tornado Watch 228 continues.

SUMMARY...The tornado and wind damage threat will continue over the
next few hours as the storms move toward the eastern edge of WW 228.
The threats are likely to affect areas to the east of the watch
toward daybreak which will probably necessitate new watch issuance.

DISCUSSION...Latest radar imagery shows a convective line of strong
to severe thunderstorms ongoing in northeast Kansas and far
southeast Nebraska. The line is located along the northern edge of
moderate instability with a warm front extending eastward into
northern Missouri. Surface dewpoints to the south of the warm front
are lower to mid 60s F with the RAP estimating MLCAPE values in the
1000 to 1500 J/kg range. In addition, the Kansas City WSR-88D VWP
shows moderate deep-layer shear with a looped hodograph and 0-3 km
storm relative helicities near 500 m2/s2. This will support a
tornado threat with the stronger cells embedded in the line. Wind
damage will also be possible along the leading edge of the line.
