From freezing to triple digits, the region has seen a mix of January and July temperatures this week.
We already know that Omaha set a record daily low of 32 degrees Sunday morning and two days later set a record high of 101 degrees on Tuesday.
But another notable aspect of those temperatures: Within the same week, Omaha came within a whisker – one day – of having both its coldest weather latest in the spring and its warmest weather earliest in the spring. And that's over 135 years of records.
Previously, the latest the temperature had dropped to 32 degrees in Omaha was on May 13, back in 1997. This week, that happened on May 12.
Prior to Tuesday, the earliest Omaha had topped 100 degrees in the past 135 years was two weeks later in the month – May 29, 1934, when the mercury peaked at 102 degrees.
Also worth noting: Despite the extraordinary 108 degrees Tuesday in Tekamah, the state has seen higher temperatures in May. According to Natalie Umphlett, regional climatologist at the High Plains Regional Climate Center, some Nebraska temperatures reached 109 degrees in May 1934 and 110 degrees in May 1895.
