...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PORTIONS
OF CENTRAL NEBRASKA...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER NORTH-CENTRAL
WYOMING...

...SUMMARY...
Scattered severe gusts (some 75+ mph) and large hail are probable
across parts of central Nebraska this evening.  Isolated severe
gusts are also possible from the Upper Midwest to Utah and Wyoming
through mid-evening.

...SD/NE...
An organized linear MCS has become established from eastern SD into
central NE.  These storms have product several reports of locally
damaging winds and some large hail.  This QLCS will progress
east-southeastward through the evening into western IA and southeast
NE, with a continued severe threat.  Reference MCD #1679 and WW #514
for further details.

...Northern WY/Western Upper MI...
A line of intense thunderstorms is tracking eastward along and south
of the WI/Upper MI state line.  These storms have produced sporadic
damaging wind gusts over the last few hours, and are probably
past-peak.  Nevertheless, a few severe storms will remain possible
for another 2-3 hours.  Reference WW #513 for further details.

...WY...
Scattered high-based thunderstorms continue to develop and spread
across much of western and central WY.  The strongest cells in this
area will maintain some risk of damaging wind gusts for a few more
hours until diurnal cooling diminishes the threat.  Reference WW
#515 for further details.

...Southeast AZ...
Scattered thunderstorms continue to develop in a warm/moist
environment over southeast AZ.  This activity will slowly build
westward for the next several hours, with a risk of gusty/damaging
winds.  Reference MCD #1680 for further details.
