WILL WORK EAST TOWARD A NORFOLK TO LINCOLN LINE BY NOON. THESE
STORMS GENERALLY WILL NOT BE SEVERE...BUT SMALL HAIL AND GUSTY
WINDS WILL BE POSSIBLE.

THEN THIS AFTERNOON...THE COMBINATION OF DAYTIME HEATING...
INCREASING HUMIDITY...AND STRONGER WIND SHEAR WILL LEAD TO THE

CONCENTRATED AREA OF STORMS IS EXPECTED ALONG AND NORTH OF A
NORTHWARD MOVING WARM FRONT. STORM CHANCES WILL INCREASE MARKEDLY

DAKOTA INTO ADJACENT SECTIONS OF NORTHEAST NEBRASKA AND NORTHWEST
IOWA LATE THIS AFTERNOON AND EVENING.

THE THUNDERSTORMS WILL CONTINUE INTO THE EVENING AS THEY TRACK
SOUTHEAST ACROSS EASTERN NEBRASKA AND SOUTHWEST IOWA BEFORE
MOVING OFF TO THE EAST LATE TONIGHT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THERE IS A SLIGHT CHANCE FOR THUNDERSTORMS SUNDAY AFTERNOON IN
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AS A COLD FRONT MOVES
THROUGH THE AREA. THEN AS THAT FRONT LIFTS BACK NORTH ON
MONDAY...MORE STORMS ARE POSSIBLE ACROSS ALL OF EASTERN NEBRASKA
AND WESTERN IOWA. THERE IS A SMALL CHANCE FOR SEVERE STORMS DURING
EACH OF THESE PERIODS.

THEN THERE WILL BE A DAILY CHANCE OF THUNDERSTORMS THE REST OF THE
WEEK TUESDAY THROUGH FRIDAY AS SEVERAL WEATHER IMPULSES MOVE
ACROSS THE REGION.
