Areas affected...Southeastern Nebraska
Concerning...Tornado Watch 187...190...
Valid 062227Z - 070000Z
The severe weather threat for Tornado Watch 187, 190 continues.
SUMMARY...A line segment in southeast Nebraska will continue to move
into a destabilizing environment this evening with aid from
mid-level ascent. Severe winds and QLCS circulations/tornadoes will
be possible.
DISCUSSION...A more organized line of storms has developed in
south-central Nebraska. Though buoyancy has been limited by cloud
cover, regional surface observations show dewpoints reaching the low
60s F ahead of this line. This moisture advection should continue
this evening. Objective mesoanalysis shows 1000 J/kg MLCAPE in far
southeast Nebraska currently. This line of storms will be capable of
severe wind gusts and is expected to persist as continued mid-level
ascent pushes into central/eastern Nebraska this evening. QLCS
circulations/tornadoes are also possible. KUEX has showed occasional
low-level velocity couplets over the last hour. The northward extent
of the threat is a bit uncertain as destabilization becomes less
likely farther north.
