SIOUX FALLS, S.D. (KELO AM) - Enjoy today's weather because the heat and humidity will start building tomorrow over the northern plains.
Sioux Falls forecaster Kyle Weisser doesn't anticipate record high but the dew point will be in the mid 70's.
Weisser advises avoiding the outdoors between noon and 7 p.m. when the heat index is 100 or more. He says it's possible the heat index will reach 110 Thursday or Friday.
Weisser says both the heat and humidity should break by the weekend.
