Another day of dangerous heat is expected today. In fact, today will be the hottest day of the heat wave thus far. Excessive Heat Warnings and advisories are in effect across much of the central part of the country.
A breezy southwest wind today ahead of a cold front crossing the Dakotas will bring hotter air into the area. Combined with plenty of sunshine, look for highs from 95 to 100. The humidity may come down a little, but still expect heat indices (what the temperature really feels like) this afternoon and early this evening between 105 and 115 degrees
The cold front is expected to weaken as it makes its way through the area tonight. Some storms could occur along the front, but there is a lot of uncertainty if they will develop. If they do develop along the front during the evening from southern Minnesota into north central Wisconsin, the environment is favorable for them to produce damaging winds and heavy rain. Those storms that develop after midnight should only have a threat of heavy rain. With the cold front coming in, lows will drop into the low to mid 70s.
Another warm and humid day is expected on Thursday. However, with highs only topping out in the 80s to low 90s and slightly drier air moving in, look for peak heat indices in the 90s to near 100. The highest heat indices will occur over Fayette and Clayton counties of Iowa, and Crawford, Richland and Grant counties in Wisconsin.
Plan on warm and humid weather along with the chance of storms to continue for Friday into the weekend, but the heat will not be nearly as oppressive as today or earlier in the week.
Be prepared for the heat! These conditions will lead to a heightened risk of heat-related illnesses, especially for those who are sensitive to the heat, such as young children and the elderly. Drink plenty of water and try to stay in air-conditioned rooms if you don't have outdoor activities planned. Don't forget about pets and other domesticated animals too!
