Nebraska is set for drastic temperature shifts this weekend as a cold front moves through, followed by high fire danger later in the week. Residents across Omaha and surrounding areas should prepare for frost Sunday morning and freezing temperatures by Tuesday. As the cold front intensifies, temperatures will drop to the low 30s at night, with daytime highs barely reaching 60 degrees. The National Weather Service warns that frost is likely on Monday morning, with the possibility of a freeze early Tuesday. By midweek, warmer conditions will return, but they bring the risk of very high fire danger.
