The morning hours will be fairly comfortable as we start off the day in the mid-60s. Lower humidity and a light south breeze will help to make things feel comfortable through mid-morning, but strong sunshine will heat us up quickly. Temperatures will push back into the mid and upper 80s by Noon, jumping into the 90s by early afternoon. High temperatures should top out in the mid and upper 90s for most of the area, between 96 and 98 for most of the Omaha metro. Not quite as hot as the previous heat wave, but something you’ll still need to plan for if you will be spending a lot of time outdoors this weekend.
