A very atypical early spring storm brought a mix of winter weather and severe thunderstorms to eastern Nebraska April 9th and 10th.  An Arctic cold front pushed across the area early on April 9th bringing subfreezing temperatures to northeast Nebraska.  Meanwhile, a large upper level low pressure system tracking northeast out of the southern Rockies fed warmer and unstable air across the area above this shallow cold air.  A mix of freezing rain and snow spread over northeast Nebraska during the morning of the 9th and by afternoon scattered thunderstorms developed and moved across that area.  These storms intensified the freezing rain, mixing at times with heavy sleet and in some cases even large hail.  Farther southeast, even with temperatures in the 30s and 40s, severe thunderstorms developed during the evening that produced even larger hail.  One storm that moved across the western sections of the Omaha metro caused extensive damage as it dropped quarter to golf ball-size and even larger stones that covered the ground.  The freezing rain and sleet caused some power outages in northeast Nebraska along with the cancellation of school on the 10th.
