Near term [through tonight]
An upper level shortwave trough will continue to move northeast of
our area this afternoon. However, instability continues to increase
with daytime heating, and SBCAPE values of 1000-1500 j/kg have
developed across much of our area. We are already seeing some
heavier showers develop across the inland fl panhandle and se
alabama, and hi-res models suggest this will likely spread into sw
georgia later this afternoon into the evening. Any remaining showers
or storms should dissipate shortly after sunset with loss of
instability, and dry conditions are expected through the overnight
hours. With a moist boundary layer, decreasing winds, and clearing
skies late tonight, dewpoint depressions will approach zero and
areas of fog could develop during the early morning hours. Low
temperatures are expected to range from the upper 50s to lower 60s
across our area.

Short term [Monday through Tuesday night]
Weak upper level and surface ridging will be in place at the
beginning of the short term. This upper level ridging is pushed
eastward though by Monday night as a shortwave moves into the
tennessee valley. The cold front associated with this system moves
into the southeast Monday night and while the main surface low
shifts to the mid-atlantic by Tuesday evening with the front also
shifting eastward, a portion of the boundary will linger near the
cwa on Tuesday. Isolated showers and thunderstorms will be
possible mainly inland on Monday and while there is the lingering
boundary north of the CWA on Tuesday, an upper level ridge builds
in later in the day, helping to limit convection.

High temperatures will continue to be above average with highs in
the low to mid 80s, except 70s along the coast. Lows will range
from the upper 50s to lower 60s.

Long term [Wednesday through Sunday]
Surface and upper level ridging will help to make for a mainly dry
start to the long term. Widespread rain chances will return for
Friday as a cold front moves through the cwa. There is a decent
amount of instability and shear with the system and thus the
severe potential will need to be monitored, but given the system
is still 5 days out, there is time for the setup to change.

The area will dry out for Saturday.

Aviation [through 18z Monday]
Vfr conditions are likely to prevail this afternoon and evening;
however, increasingly unstable air could lead to scattered showers
and thunderstorms across inland portions of our area this afternoon.

The most likely terminals to see a brief shower or thunderstorm are
aby, vld, and dhn, but any drops in visibility will be short-lived.

Any remaining showers will end this evening, although fog could
develop early Monday morning. A few hours of ifr/lifr conditions are
possible from 09z-14z, with highest chances at dhn, tlh, and ecp.

Expect any fog to dissipate shortly after sunrise, withVFR through
the remainder of the morning and early afternoon.

Marine
Winds will generally remain 10 knots or less through mid-week but
winds and seas will increase to cautionary levels late in the week
as a cold front moves through. This front on Friday will also
bring the best rain chances to the marine area over the next week.

Fire weather
Red flag conditions are not expected for the next several days with
relative humidity values remaining above critical levels.

Hydrology
Rainfall amounts will be limited through much of the week. A cold
front will push through Friday bringing widespread rain to the
area. The system is forecast to push through the tri-state area
quickly and thus at this point, there are no flooding concerns.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
