In the wake of this mornings cold front, surface high pressure building in from the north will maintain these below normal temps through Friday.
The next weather impact will be coming this weekend. An area of low-pressure will pass closer than normal to the area, right across Arkansas and northern MS/AL Sunday night. This will bring a surface low with cold front through the area. SPC outlook has the area as marginal risk for severe storms and that seems quite appropriate. The bulk of convection will impact the area Sunday with precipitation chances at 70 to 80% range.
Cooler and drier air will filter into the region Monday. There could be a few lingering showers north of I-12 as mid/upper level moisture wraps around the upper low before it ejects eastward. Upper ridge will quickly move in Tuesday through Thursday. This will result in a quick rebound of temperatures.
