.NEAR TERM [Through Tonight]...
Fairly light WNW flow across the region today will keep rain chances
on the low side through the evening hours. Any showers/storms that
develop this afternoon are expected to dissipate by sunset. Expect
mostly clear skies overnight with low temperatures generally in the
.SHORT TERM [Thursday Through Friday Night]...
Weak frontal boundary will sag into the area Thursday and move
slowly through the area through Thursday night. The frontal
boundary will provide the best focus for rainfall across the
central and southern portions of the area. Expect around a 50%
chance in these areas with decreasing chances across SE Alabama
and portions of SW Georgia. The front appears to be just south of
our coastal waters Friday with the better chances for rainfall
across the southern half (mainly Florida counties) of the area. No
real change in airmass behind the front so expect highs in the
lower 90s each day and lows Thursday night in the mid 70s.
.LONG TERM [Saturday Through Wednesday]...
Again, model variability between the solutions (and run to run
variability) pertaining to the eventual evolution to what is now
(again) TD Harvey may or may not have an impact on our weather and
forecast. Due to this, I have favored a persistence forecast from
the previous shifts. Therefore, will continue typical afternoon
and evening showers and storms at a 30-50% chance each day. Highs
will be in the upper 80s to lower 90s for highs and lows in the
70s. This is a low confidence forecast with high variability
depending on the eventual track of Harvey. Otherwise, the area
will remain in light WNW mid level flow with a NW to NE surface
.AVIATION [Through 18Z Thursday]...
VFR conditions are expected to prevail through the afternoon/evening.
Sct TSRA are starting to develop NW of DHN and may impact that
terminal through this afternoon. Elsewhere, coverage is expected
to be too isolated to include in the TAFs. VFR overnight and into
Thursday except at VLD where a brief MVFR restriction before
sunrise is possible.
Light winds and low seas will prevail through Saturday. Beginning
Saturday night, moderate winds and seas are expected as high
pressure across the northeast Gulf interacts with low pressure in
the western Gulf. Showers and storms can be expected each day.
Hazardous fire weather conditions are not expected over the next
Scattered showers and thunderstorms are expected over the next few
days. Localized ponding of water is possible in poor drainage
areas with the heaviest rainfall, but widespread flooding is not
