Temperatures have climbed in to the middle and upper 90°s Wednesday afternoon. Dew points have been very oppressive, sending the heat index to levels not felt in nearly two years. The heat index peaked at 109° in Columbus and 108° in Lincoln.
The air temperature reached 98° in Lincoln. This is the warmest the city has been on this date in 22 years. The peak heat index (108°) is also the highest level the city has encountered since August 2019.
I do see some relief from the high temperatures coming our way – starting as early as Thursday – thanks in part to a weak cold front passing through the region. However, it isn’t going to feel much cooler. With high humidity tomorrow, the heat index will range from 100° to as high as 110° in parts of southeast Nebraska. The air temperature will top out in the 90°s.
As the upper-level hot dome begins to move to the south/southwest, a cold front will begin moving through southeast Nebraska, increasing the chance for a few showers and thunderstorms late afternoon and evening.
The chance for daily showers and thunderstorms will continue Friday and again Saturday. This will help keep temperatures lower, falling below 90° starting Friday and continuing through all of next week.
