THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 504
CONTINUES.

SUMMARY...WHILE ISOLATED INSTANCES OF HAIL OR GUSTY WINDS REMAIN
POSSIBLE ACROSS THE REMAINING PART OF WW 504 AND ADJACENT AREAS TO
THE EAST...THE OVERALL SEVERE THREAT SHOULD CONTINUE TO DIMINISH
OVERNIGHT.

DISCUSSION...INTENSITY OF CONVECTION FROM SERN NEB INTO IA CONTINUES
TO SLOWLY DIMINISH AS OF 0430Z...WITH MOST OF THE ONGOING ACTIVITY
BECOMING INCREASINGLY ELEVATED ATOP COMPOSITE OUTFLOWS. PRIMARILY
SMALL HAIL REMAINS POSSIBLE WITH THE STRONGER CORES...WITH
DIMINISHING INSTABILITY REDUCING THE SEVERE HAIL THREAT. GUSTY WINDS
REMAIN POSSIBLE ALONG THE LEADING EDGE OF THE OUTFLOW NOW MOVING OUT
OF THE WATCH INTO SRN/ERN IA...BUT THE SEVERE WIND THREAT SHOULD
REMAIN TOO LIMITED FOR ADDITIONAL WW ISSUANCE.
