THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHEAST
NEBRASKA.

.DAY ONE...TONIGHT AND SUNDAY

THERE IS A SLIGHT CHANCE FOR SEVERE THUNDERSTORMS CONTAINING LARGE
HAIL AND DAMAGING WINDS THIS EVENING...GENERALLY NORTHWEST OF AN
ALBION TO WAYNE LINE.

A LOW PRESSURE SYSTEM MOVING NORTHEAST INTO CENTRAL SOUTH DAKOTA
WILL PUSH A FRONTAL BOUNDARY INTO NORTHEAST NEBRASKA TONIGHT.
THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THIS FRONT...WITH
MODERATE INSTABILITY AND SHEAR LEADING TO THE POTENTIAL FOR SEVERE
STORMS. AS THE EVENING WEARS ON...THE CHANCE FOR STORMS WILL
SPREAD EAST TOWARD THE MISSOURI RIVER...BUT DECREASING INSTABILITY
SUGGESTS THE SEVERE THREAT WILL DIMINISH.

.DAYS TWO THROUGH SEVEN...SUNDAY NIGHT THROUGH SATURDAY

THUNDERSTORM CHANCES WILL REMAIN IN THE FORECAST THROUGH
THURSDAY AS A FRONTAL BOUNDARY MOVES INTO THE AREA AND THEN
STALLS. THE FRONT WILL BE THE FOCUS FOR SEVERAL ROUNDS OF
STORMS...ESPECIALLY ALONG AND NORTH OF IT WHERE LOCALLY HEAVY
RAIN AND STRONGER STORMS ARE POSSIBLE MONDAY NIGHT THROUGH
WEDNESDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...

THERE IS A SMALL CHANCE THAT SPOTTER ACTIVATION COULD BE NECESSARY
THIS EVENING.
