SHEBOYGAN, Wis. (WHBL) - It was already 96 degrees in Middleton at 10 Thursday morning. And places as far north as Waupaca were in the 90’s, as much of Wisconsin gears up for another 100-plus-degree afternoon. The heat index reached 100 late this morning at Sheboygan, close to where the U-S Women’s Open is being played in Kohler at Blackwolf Run. And the United States Golf Association took some additional measures to help protect spectators who are not used to being outside for so long in this type of heat. Two air-conditioned motor coaches were brought in near the main gate – and they’ll be open to all spectators throughout the day. Fans cannot bring in their own water bottles, but the precious commodity is being sold at a 2-for-1 discount at concession stands. The U-S-G-A is also asking fans to take their own steps to avoid illness – drink lots of fluids, apply sun-screen often, wear loose, light-colored clothes and hats, and bring an umbrella for shade. This is Wisconsin’s hottest spell in at least 17 years. Highs today are expected from the ‘90’s up to 106, with only a slight chance of rain through tonight. Relief is not expected until at least Saturday.
