7/20/11 – It’s Day-Four of Wisconsin’s heat wave – and it could be the hottest. The National Weather Service says temperatures will push at least into the mid-and-upper-90’s statewide this afternoon. Heat index readings will go well into the 100’s again. And some places could have their hottest day since the heat wave of 1995 – when 154 Wisconsinites died from various heat conditions. So far, at least, we have not heard of any deaths directly caused by the heat wave. Some Wisconsin electric utilities say they could break all-time usage records today due to the heavy use of air conditioning. The state’s largest electric transmission service also expects record energy flows today. The American Transmission Company says the system is in good shape. An excessive heat warning is in effect in our area until 9 pm tomorrow night.
