THUNDERSTORMS ARE LIKELY THIS EVENING AND OVERNIGHT ACROSS MOST
OF WESTERN AND NORTH CENTRAL NEBRASKA. THE GREATEST THREAT FOR
SEVERE WEATHER WILL BE SOUTH AND WEST OF A LINE FROM BURWELL TO

FOR THUNDERSTORMS TO INITIATE ACROSS WESTERN AND CENTRAL NEBRASKA.

PRODUCE LARGE HAIL AND DAMAGING WINDS. ISOLATED TORNADOES WOULD
ALSO BE POSSIBLE...ESPECIALLY SOUTH AND WEST OF A LINE FROM
COMSTOCK TO MERRIMAN...WHERE SURFACE BOUNDARIES ALONG WITH A VERY
UNSTABLE AIRMASS EXISTS.

IF STORMS DO NOT INITIATE THIS EVENING OVER WESTERN AND NORTH
CENTRAL NEBRASKA...ACTIVITY CURRENTLY OVER COLORADO AND WYOMING
WILL CONTNIUE TO WORK EAST OVERNIGHT. THIS COMPLEX OF STORMS WILL
BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.

ON SUNDAY...A COLD FRONT WILL ENTER THE NORTHWEST PORTION OF
NEBRASKA BY LATE AFTERNOON. THIS FRONT IS EXPECTED TO STALL ACROSS
THAT AREA INTO THE EVENING AND IS EXPECTED TO GENERATE
THUNDERSTORMS. IF THESE STORMS BECOME ORGANIZED...LARGE HAIL WOULD
BE POSSIBLE WITH THESE STORMS AS WELL.

AN ACTIVE WEATHER PATTERN WILL REMAIN ACROSS THE AREA INTO THE
FIRST PART OF THE WEEK...ALLOWING THUNDERSTORM CHANCES TO STAY IN
THE FORECAST.
