Overnight lows will dip down only to the middle 70s, and such warm
nights do not allow the body to recover from the heat of the day.
A cold front will produce thunderstorms Wednesday night and Thursday
morning, helping to bring the heat index values below advisory
levels for Thursday.

Heat index values will remain at dangerous levels through
Wednesday evening. The heat index will range from 105 to 110 degrees
during the afternoon and early evening hours, with actual high temps
from 95 to 100. Overnight lows in the middle 70s will offer little
relief from the heat.
Thunderstorm activity and cloud cover should move into the area

expected to pass through Thursday, helping reduce the heat.
A heat advisory means that a period of dangerously hot
temperatures is expected. The combination of hot temperatures and
high humidity will combine to create a situation in which
heat-related illnesses are possible. Drink plenty of fluids, stay in
an air-conditioned places, stay out of the sun, and check up on
relatives and neighbors, especially the elderly. Check on livestock
and bring pets indoors, especially during the afternoon hours.
