The severe weather threat for Severe Thunderstorm Watch 271
SUMMARY...The severe weather threat continues, and trends are being
monitored for the possibility of a downstream watch.
DISCUSSION...Severe thunderstorms producing damaging winds and large
continue across northwest Kansas between Goodland and Hill City at
0445z. Latest mesoanalysis reveals that these storms remain within a
region of warm advection associated with a 30-40 kt low-level jet
and along a gradient in elevated instability. A continued eastward
motion is expected, which would put the easternmost storm on the
edge of the watch by 06z. Although latest short-term guidance
suggests that this area of storms may shift east of the strongest
warm advection with time, increasing mesoscale organization of the
complex and modest elevated instability points to a continuing
severe threat into north-central/central Kansas. As a result, this
area is being monitored for the possibility of a downstream watch
prior to 06z.
