Areas affected...South-Central to Southeast Nebraska



Concerning...Heavy rainfall...Flash flooding possible



Valid 060710Z - 061015Z



SUMMARY...Locally backbuilding and training supercell

thunderstorms will continue to foster concerns for flash flooding

for a few more hours across south-central to southeast Nebraska

before the activity weakens this morning.



DISCUSSION...GOES-E IR satellite imagery shows deep cold-topped

convection associated with a cluster of locally backbuilding and

training supecell thunderstorms continuing across portions of

south-central to southeast Nebraska.



The activity remains somewhat anchored in close proximity to a

front with notable moisture convergence. A southwest low-level jet

of 30 to 35 kts interacting with the front coupled with a pool of

elevated instability with MUCAPE values near 2000 J/kg has been

helping top sustain the activity. Favorable Corfidi vector

orientations have favored much of the slow overall advance of the

convective mass over the last couple of hours with an excellent

setup for backbuilding and training convective cells.



Over the next few hours as boundary layer CIN increases further

and the low-level jet weakens, the ongoing convection should begin

to weaken and lose organization. For the next few hours, some

additional rainfall rates of 1.5 to 2 inches/hour will be

possible, and this may drive sufficient totals for some additional

areas of flash flooding. However, the consensus of the latest

hires CAMs suggest convection weakening toward dawn.
