• The National Weather Service has issued heat advisories through Thursday warning that heat index values could reach the mid-90s to around 100°F in inland areas.
• A disturbance moving northeast from the Mississippi Valley and a stalled front are expected to spark a low-end severe thunderstorm threat with scattered storms Wednesday and Thursday.
