The severe weather threat for Severe Thunderstorm Watch 433
SUMMARY...Sporadic severe storms capable of damaging winds and
localized large hail remain likely across the watch area.
DISCUSSION...A large mass of thunderstorms continues to evolve
slowly eastward out of Kansas, with multiple measured wind gusts
over 50 kt earlier. Radar indicates substantial outflow being
produced with these storms, which have been undercutting others and
limiting propagation. Recently, cells over eastern Kansas (Douglas
into Johnson counties) have shown signs of maintaining a reasonable
eastward propagational speed, with outflow remaining near the
storms. Other cells were rapidly developing ahead of it, with at
least marginally severe hail or wind expected. Surging outflow from
the west may also given an additional boost to the eastern storms.
Given strong instability surrounding these storms, strong to severe
outflow winds are possible radiating in all directions. Further
development is expected with eastward extend this evening.
