Things will change at the beginning of next week, but not too much. The GFS shows a large trough over the western U.S. during the early weekend and moves it to the west. The trough begins to demagnify Monday morning and become a shortwave. The GFS shows the wave remaining just to the north of Mississippi Monday night and Tuesday morning. The model indicates a surface low and cold front with most of the precip to the north and east of the low. The European model shows a surface low to the north, but Monday morning.
I don't get the impression of this system brining in much rain. Things should clear out by the end of Tuesday. There should be some nice weather for the short term. The GFS hints at another system moving in around next weekend. The NWS in Jackson also points out this system in their latest AFD. However, it's a week out and it's a guidance model; therefore, I don't feel confident in saying much about this system.
For now, most of the weekend looks very nice. Enjoy it!
