Morning showers and thunderstorms; Brief relief from big heat
We will get minor relief from the big heat the start of August has provided southeast Nebraska. Temperatures will only top out in the lower to middle 90°s compared to Tuesday’s temperatures around 100°.
Showers and thunderstorms will be possible through 11 a.m. Wednesday. Skies will also start mainly cloudy. As we get in to the afternoon, winds will turn out of the north and clouds will decrease.
Humidity will be slow to drop Wednesday afternoon, which means the heat index – or the “feels like” temperature – will climb in to the upper 90°s. Again, this is better than what southeast Nebraska experienced Tuesday as the heat index climbed as high as 110°.
Skies will be clear tonight and we will experience cooler temperatures Thursday morning. Lows will be in the 60°s.
While temperatures Thursday will be above normal, the humidity will be much more in check. The heat index will only be a degree higher than the air temperature.
BIG heat returns for the end of the week in to the start of the weekend. Temperatures will climb to the upper 90°s to around 100° both days. Factor in the humidity, the heat index will easily surpass 100°.
