continue to develop overnight, initially across
south-central/eastern Nebraska, while eventually expanding into
western/central Iowa and far northern Missouri. This will include
the Interstate 80 corridor. Large hail is expected to be the most
common hazard, but surface-based storm potential could increase
mainly toward/after sunrise including what could be an increasing
damaging wind risk.

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
&&
AVIATION...A few severe thunderstorms with hail surface and aloft to
3 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
25025.
