NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO
100 PM CDT MON JUN 29 1998

...SEVERE THUNDERSTORMS LIKELY TONIGHT ACROSS THE ENTIRE OUTLOOK
AREA...

FORECAST: THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A COLD FRONT
IN SOUTHEAST NEBRASKA LATE THIS AFTERNOON AND MOVE ACROSS THE
OUTLOOK AREA TONIGHT. THE STORMS ARE EXPECTED TO PROGRESS TO AREAS
WEST OF INTERSTATE 35 BY MIDNIGHT AND THEN CONTINUE SOUTHEAST
THROUGH THE NIGHT. THE PRIMARY THREAT FROM THESE STORMS IS LARGE
HAIL AND DAMAGING WINDS. HOWEVER...ISOLATED TORNADOES ARE POSSIBLE
THIS EVENING NORTHWEST OF INTERSTATE 35. IN ADDITION...HEAVY RAIN IS
ONCE AGAIN EXPECTED WITH THE STORMS...WHICH MAY CAUSE FLOODING OF
URBAN LOCATIONS...SMALL CREEKS AND LOW LYING AREAS. EMERGENCY
MANAGERS AND SPOTTER NETWORKS SHOULD PREPARE FOR POSSIBLE ACTIVATION
TONIGHT.

SCATTERED THUNDERSTORMS ARE ALSO EXPECTED THIS AFTERNOON...BUT ARE
NOT EXPECTED TO BE SEVERE.

DISCUSSION: A COLD FRONT ACROSS EASTERN NEBRASKA WILL SWEEP
SOUTHEAST ACROSS THE AREA TONIGHT. THE ATMOSPHERE WILL REMAIN VERY
UNSTABLE IN ADVANCE OF THE FRONT. DESPITE THE COOLING DURING THE
NIGHT...THE FRONT IN COMBINATION WITH A WEAK UPPER LEVEL DISTURBANCE
WILL TRIGGER THUNDERSTORMS THROUGH THE NIGHT. WIND PROFILES SUGGEST
THAT ISOLATED TORNADOES ARE POSSIBLE BEFORE MIDNIGHT.
