Tonight through Sunday night: A persistent southerly flow weather pattern will continue this weekend with the center of a warm subtropical high shifting slowly eastward across the southeast CONUS. Mild nights and warm days will continue with gusty wind peaking during the daytime. Sunday night, a significant shortwave trough crossing the Central Plains to Mid MS Valley region will send a weakening cold front into our forecast area. Most of the energy associated with this will be deflected around our area by the ridge, but there will be enough moisture convergence for a few storms. Given the weakening lift and modest instability/deep layer shear, the potential for any severe storms is very limited and confined mainly to the upper ArkLaMiss Delta. /EC/
Monday through Thursday night: The weather can be best described as unsettled for much of next week. A weak frontal boundary will reside over the Deep South and serve as a focus for moisture and limited instability with shower and thunderstorm chances persisting each day. The challenge will be determining if/when we will encounter an organized storm threat and the potential for any strong/severe storms. As of now there are not specific times we are focusing on in the synoptic pattern, and can imagine that mesoscale influences will have a lot to say about how deep convective threats evolve, so will continue to monitor trends in the guidance. In any case, there are no significant signals showing up in the convective parameters for severe weather/heavy rainfall. /EC/

Low stratus will continue to slowly erode across the area early this afternoon, with ceilings improving. This will eventually give way to VFR flight categories at area TAF sites through the remainder of the afternoon into this evening. Winds will be breezy from the south today, and generally sustained between 10-15 knots with gusts around 25 knots at times, especially across the Delta region, KGLH & KGWO. Winds will subside a bit this evening, but will generally remain between 5-10 knots areawide, with low stratus again developing across the majority of the area toward day break Saturday and reducing categories to MVFR status. /19/
