.UPDATE...TONIGHT...
SOME THUNDERSTORM REDEVELOPMENT CONTINUES ALONG THE SOUTHERN
LARAMIE RANGE THIS EVENING FOLLOWING THE PASSAGE OF THE STRONG
THUNDERSTORMS EARLIER. STRONG THUNDERSTORMS ALSO CONTINUE TO
PROGRESS ACROSS THE NEBRASKA PANHANDLE. THE SEVERE THUNDERSTORM
WATCH REMAINS IN EFFECT THROUGH MIDNIGHT MDT.

THIS EVENINGS THUNDERSTORM ACTIVITY APPEARS TO BE THE RESULT OF
THE ARRIVAL OF THE STRONG JET MAX ALOFT COMBINED WITH THE PRESENCE
OF THE 700 MB TROUGH OVERHEAD. ALL OF THE FEATURES PRESENT ARE A
RESULT OF THE UPPER LEVEL TROUGH MOVING ACROSS THE NORTHERN
ROCKIES AT THIS TIME.

HAVE INCREASED PRECIPITATION CHANCES IN THE NEBRASKA PANHANDLE
WITH THIS UPDATE AS THE SUPPORT FOR CONTINUED SHOWERS AND
THUNDERSTORMS THROUGH MIDNIGHT AND OVERNIGHT APPEARS GREATEST
THERE.
