Now through Monday...

An upper ridge stretching north over the eastern Conus will build as
an upper trough digs over the western Conus through mid week. Energy
from the western upper trough ejects, flowing through the flow over
the eastern upper ridge, helping to deamplify the ridge. The ridge
keeps the bulk of the energy north of the forecast area into the
coming weekend, though. The ridge also helps to maintain a surface
ridge stretching southwest along the East coast. This surface ridge
in concert with a developing surface low over the Plains increases
onshore flow over the Lower Mississippi River Valley, then the
Southeast the end of the week into the weekend before a cold front
crosses these regions Friday night into Saturday. Precipitable h20
values creep up to around 1.7" ahead of the approaching front. Rain
returns to the forecast area Friday, lasting into the weekend in
response, though with the better upper dynamics passing north of the
forecast area, the resultant higher PoPs occur over northwestern
portions of the forecast area Friday/Friday night. The risk of any
rowdy storms Friday/Friday night is low, with limited instability
(MUCapes < 800J/kg) along with meh wind shear (Bulk Wind shear
<=32kts). The more progressive nature of the passing upper dynamics
will also help to limit any water issues.

Fog development is likely tonight, and again Wednesday night, with
enough mixing combined with a very moist boundary developing as
temperatures cool overnight. A Dense Fog Advisory is in effect
tonight, starting at 06z/midnight, for areas over and west of a
Baldwin County to Clarke County.

Upper subsidence from the upper ridge will keep temperatures will
above seasonal norms through the forecast. High temperatures in the
upper 70s to around 80 well inland, mid 70s along the coast are
expected through the forecast. Low temperatures see an upward creep
through the rest of the week until the front`s passage this coming
weekend. Mid 50s to around 60 expected Wednesday night rise into the
mid to upper 60s Friday night. Post frontal, low temperatures drop
into the low 50s north of Highway 84 to upper 50s south of I-10
Sunday night.

Onshore winds increase through the week, with the Rip Risk
increasing to Moderate to High Friday night through the weekend.
