Key Messages
- Hot conditions resume tomorrow and peak in some areas Wednesday as humidity increases, but a cold front may limit how much of the area sees truly impactful heat and humidity.
- Confidence is growing in a round of widespread showers and thunderstorms from late Wednesday afternoon through early Thursday morning. Locally heavy rain and occasional strong downburst winds are the most likely hazards.
