A heat advisory remains in effect until 7 p.m. Wednesday.
The National Weather Service in Shreveport said an upper level ridge will remain in place across the Southern Plains through Wednesday.
This will result in afternoon temperatures climbing into the mid 90s to near 100 degrees.
Southerly winds will maintain the high humidity through Tuesday, with resultant heat indices ranging from 105 to 110 degrees.
High heat index readings will increase the risk of heat-related illnesses.
Isolated to scattered showers and thunderstorms will be possible through much of the extended period of the forecast with the highest chances across the eastern half of the Four State Region.
Precipitation coverage may pick up by late in the work week into the weekend due to a disturbance moving in from the north and west.
