...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN EASTERN NE TO
FAR WESTERN IA...

...SUMMARY...
Strong to severe thunderstorms should persist for a few more hours
across a portion of eastern Nebraska into far western Iowa, before
diminishing tonight.

...01Z Update...
Most of the severe threat across the central and northern Great
Plains has diminished and this trend should largely persist through
the rest of evening. One exception, where a severe wind and brief
tornado threat should persist, is across eastern NE into far western
IA. A leading supercell over south-central NE has recently become
absorbed into a mostly non-severe QLCS. This process may yield some
short-term strengthening of the severe wind threat along the south
side of the QLCS amid a 45-kt low-level jet per UEX VWP data.
Further increase of the low-level jet through the evening will
probably maintain a threat for strong to locally severe wind gusts
despite the more hostile airmass for surface-based convection near
and east of the MO River, per the 00Z OAX sounding.

A lone high-based supercell in east-central WY may persist
east-southeast along the surface front for a couple more hours, with
some potential for an addition storm or two to form after dusk.
Marginal severe hail and wind will remain possible.
