FORECAST IN DETAIL

July is turning into a hot mess. Not unprecedentedly so. But a hot mess nonetheless. Temperatures trend higher today and even higher tomorrow. Then Friday through Sunday could be exceedingly hot, with the humidity remaining a force throughout.

Today (Wednesday): The heat isn’t as extreme as it may be tomorrow and through the weekend. But with partly to mostly sunny skies, highs reaching the mid-90s aren’t exactly refreshing. Add in the high humidity, and we’ll see the afternoon heat index near 100, with the possibility of an isolated afternoon storm. Confidence: Medium-High

Tonight: After the chance of an isolated evening storm, we’re mostly clear and muggy through the night. Lows settle in the 70s. Confidence: Medium-High

Tomorrow (Thursday): A touch hotter tomorrow as highs likely climb into the mid- to upper 90s. The high humidity should push the heat index into the 100-105 range. Skies should again be partly to mostly sunny, and a cooling shower or storm seems unlikely. Confidence: Medium-High

Tomorrow night: Evening temperatures slowly edge themselves back into the 80s. Eventually overnight lows make their way down to the simmering mid-70s to near 80 under partly cloudy skies. Confidence: Medium-High

A LOOK AHEAD

Friday through Sunday looks steamy any way you slice it, with the potential to be dangerously hot and humid. Highs head for the mid-90s to near 100, with the heat index as high as 105-110. Only a slight chance of a storm on Friday, with a 30-40 percent chance of some showers and storms Saturday and Sunday. Confidence: Medium
