The final week of August is going to be one of the hottest on record for some areas. The good news is that the humidity won’t be much of a factor beginning Monday.
The National Weather Service in Des Moines says:
Some areas will reach the upper 90’s and heat index values will approach 100 degrees at times.
The normal high for this time of the year in Waterloo/Cedar Falls is 82*. Last year during this same week, the high temps failed to even reach 80*!
