An upper ridge from TX to ND this afternoon slides east and flattens over the southeast US late Sun. As a result northwesterly flow aloft the area become nearly zonal. At the surface high pressure in the Deep South shifts offshore tonight and continues east Sunday while continuing to stretch back across FL.

The dry air and sunny skies of this afternoon give way to increasing moisture as lower level flow gradually shifts from northerly to southeast and south for Sun. There will be a few more clouds around along with isolated/scattered showers or storms in the afternoon from Polk county south and southwest. Temperatures will be below normal in the north and around normal for Sunday morning...highs will reach the mid to upper 80s along the coast to lower 90s inland.

Monday though next Saturday: Nearly zonal flow continues across the Gulf region for much of the week as a series of short wave troughs track through the northern tier of states. On Fri a more robust short wave trough reaches the Great Lakes with a trough reaching down into the Gulf of Mexico. This short wave trough moves to New England Sat...dragging the Gulf trough into the Atlantic. Atlantic high pressure ridges across FL to the Gulf of Mexico until Thu when it slips away as a cold front...accompanying the upper tough...moves into north FL and slides across the state early Fri. High pressure begins to build in from the eastern states Sat.

Moisture will continue to slowly increase until the frontal passage Fri then drying begins to work in. Isolated to scattered showers and storms are expected in the afternoons...mainly inland thanks to sea breezes...through Wed. The front and upper troughiness will increase coverage Thu and early Fri...then any rain chances end. Temperatures run warm but dip some toward the end of the week.

Some high mixing heigheights will create locally higher dispersions during the next couple of afternoon.
