The weather is expected to return to Omaha, Nebraska, and Iowa this week, with temperatures reaching a record-breaking high of 91, according to the National Weather Service. This comes as temperatures are expected to remain warm throughout the week. The forecast predicts that temperatures will drop to below 40 degrees later in the week and temperatures will continue to fluctuate throughout the day. Despite this, there are concerns that this could be another dampening period for allergy sufferers due to the weather. The temperature is predicted to drop to 40 degrees in the coming days. The record high for Omaha is 91, but it is likely not quite that hot, with highs reaching 91, and temperatures reaching 80 degrees.
