Temperatures peaked in the mid-to-upper 80s across much of the area Wednesday afternoon. But it was a comfortable heat thanks to the low humidity (dew points in the 50s). You’ll notice more of a sweat factor with the heat on Thursday. Nothing oppressive, but enough moisture in the air to threaten a couple of showers or storms.

Through Tonight: Temperatures gradually work their way back through the 80s as we head through early evening, then into the mid-to-upper 70s by mid-evening. Overnight lows range through the 60s under mostly clear skies.

Tomorrow (Thursday): Temperatures are about the same tomorrow, with afternoon highs around 85 to 90. But the humidity is more noticeable, as a light wind from the south pushes dew points past the 60-degree mark. The moister air mass means partly cloudy skies and the potential for a few scattered showers and thunderstorms during the mid-afternoon into evening. Any storm would be capable of a brief burst of heavy rain and lighting, but as of now the threat of severe winds and hail looks to be on the low side.
