Mesoscale Discussion 1079
NWS Storm Prediction Center Norman OK
0921 PM CDT Wed Jul 18 2018
Areas affected...Much of eastern Nebraska
Concerning...Severe Thunderstorm Watch 281...
Valid 190221Z - 190415Z
The severe weather threat for Severe Thunderstorm Watch 281
continues.
SUMMARY...A few storms capable of hail and locally strong wind gusts
remain possible across eastern Nebraska. Isolated storms may
eventually affect northern Kansas, but a watch may not be needed.
DISCUSSION...Storms across NE has remained largely cellular this
evening owing to lengthening hodographs and sufficient low-level
SRH. 00Z soundings from the area indicate a marginally unstable
environment with relatively poor lapse rates aloft, yet ample
low-level moisture. Some increase in the southerly low-level jet
this evening may support a continued severe threat over far southern
NE and into northern KS, as capping remains minimal. However, it is
unclear whether a new watch will need to be issued at this time,
especially if storms remain isolated.
