A boundary draped from northern Mississippi, to near Shreveport will stay north of the south Mississippi. Upper level high-pressure to the SE will slowly build and move closer to the area by mid-week/Thursday and Friday. This will allow for subsidence heating that pushes daytime temperatures abnormally hot, to near 90 in the more interior locations. Meanwhile, amplifying southern branch disturbance developing over the Pacific Southwest will become the next spring storm over the Plains States this weekend. It will push a surface front into the forecast area Saturday but meet considerable resistance from the upper ridge that would be over the eastern gulf by that time. Front should have enough integrity and upper flow support to move through Sunday. This is expected to spell cooling to near normal levels with continental high pressure influences.
