Areas affected...Northern and Eastern Kansas...Western Missouri

Concerning...Severe Thunderstorm Watch 346...347...

Valid 090810Z - 091015Z

The severe weather threat for Severe Thunderstorm Watch 346, 347
continues.

SUMMARY...A wind-damage and hail threat will continue for several
more hours as a linear MCS moves southeastward across eastern Kansas
and into western Missouri.

DISCUSSION...The latest mosaic radar imagery shows a well-developed
bowing line segment moving southeastward around 45 knots through
northeast Kansas. Convection also extends northwestward across
northern Kansas into far southern Nebraska. These storms are located
on the northern edge of moderate instability in a very moist airmass
with surface dewpoints in the lower 70s F. The line of strong to
severe storms is supported by a 40 to 50 kt low-level jet which is
analyzed by the RAP from the Texas Panhandle northeastward into
western and central Kansas. The low-level jet and instability will
help to continue to maintain intensity with the MCS for several more
hours. As the linear MCS moves southeastward across the remainder of
eastern Kansas and into western Missouri, wind damage will be likely
along the leading edge of the system as it tracks
south-southeastward along a gradient of instability. Hail will also
occur with the stronger cells embedded in the line. An isolated hail
threat will also be possible northwestward across northern Kansas as
well.
