-Oppressive heat will continue this Sunday and into some of this coming work week
-Upper ridge will move west early this week...which will bring some slight relief for portions of the state
-Some chances for afternoon convection return to the forecast today...and especially for Monday as a weak front moves into the state
-Stronger front may bring more significant relief from the heat late this week into the upcoming weeke...
