The buildup toward Wednesday begins Monday, with a high of 85 degrees and a heat index of 90, followed by Tuesday’s slightly warmer 86 degree high and 92 degree heat index as the pattern intensifies through the middle of the week.

Thursday will still feel hot, with a high of 85 degrees and a heat index reaching 91 degrees, keeping conditions similar to earlier in the week. Some easing is expected by Friday, when highs are forecast to drop to 80 degrees with a heat index of 84.
