Discussion Updated for latest aviation discussion below.

Aviation
12z issuance... A post-frontal cloud shield extends westward to the
mississippi river for the forecast area. Am expecting low end
MVFR to ifr level CIGS through the morning into the afternoon
hours until the shield mixes out or moves east. This will be slow
to occur with a front stalling along i65 this morning. After the
breakup occurs,VFR cigs/visbys expected through the rest of the
forecast.

Aviation...

12z issuance... MVFR to ifr conditions this morning in scattered
rain showers. The rain will end from west to east this morning
withVFR conditions developing through the afternoon. Low clouds
and patchy fog develop late tonight into Friday morning with MVFR
conditions possible. /13
prev discussion... /issued 448 am cdt Thu apr 27 2017/
near term /now through Thursday night/... A cold front continues
to make slow progress across southeast mississippi this morning
and slowly shift eastward through the day. A broken line of
showers and thunderstorms along the front continues to move east
and weaken as the upper dynamics move well north of the region.

Therefore, the severe threat for the rest of the day is very low.

The cold front is expected to stall across eastern zones this
afternoon and have maintained chance pops across the eastern third
of the area through the afternoon hours. A drier and cooler
airmass will work into western areas in the wake of the front
briefly this afternoon as the front stalls out. The front will
rapidly return northward as a warm front tonight as the next storm
system develops across the western states. An isolated shower is
possible along the retreating front, however the probability is
too low to include at this time. Highs today will climb into the
low 80s inland to upper 70s along the coast. Lows tonight range
from the low 60s across northwest areas to low 70s along the
coast. /13
short term /Friday through Saturday night/... An upper level ridge
of high pressure will continue to build from the fl peninsula to
the western atlantic through Saturday night, while the next upper
level low pressure system deepens over the four corners region
Friday, then advances eastward toward the tx/ok panhandles
vicinity Saturday into Saturday night. Our forecast area will
remain within a mean southwest flow pattern aloft between these
features through Saturday night. A southerly low level flow,
breezy at times, will persist across our region through the short
term period between a surface ridge of high pressure over the
western atlantic and the deepening low pressure system over the
plains. Plentiful low level moisture will continue to stream into
the area on the southerly winds through Saturday night, with
surface dewpoints looking to range from the mid 60s to lower 70s.

Short term models continue to trend with potential development of
isolated showers and possibly a thunderstorm within the low level
warm advection regime Friday, particularly during the morning
hours, and have maintained a slight chance of convection across
the region. Rainfall amounts should be light. A deep layer dry
airmass within the southwest flow should allow for dry weather
Friday night. Highs Friday look to range from the mid to upper 80s
inland, with upper 70s to lower 80s along the beaches. Lows Friday
night will be warm, with readings ranging from around 70 to the
lower 70s.

A similar pattern will continue Saturday, with southwest flow
aloft continuing in advance of the deep upper level low/trough
over the southern rockies and adjacent plains states. Weak ascent,
available instability and a slight increase in deep layer moisture
will favor development of isolated to scattered showers and
thunderstorms around the region Saturday, and will keep 20-30%
pops in place. Coverage should tend to decrease by Saturday
evening. Highs Saturday are once again forecast to range in the
mid to upper 80s inland, with upper 70s to lower 80s anticipated
again along the immediate coast and beaches. /21
long term /Sunday through Wednesday/... We are still expecting a
potential severe weather and heavy rainfall event to impact much
of our forecast area Sunday into Sunday night. The aforementioned
deep upper level low will lift northeastward across ok/ks during
the day Sunday, while an associated cold front advances eastward
across the mississippi valley region. Deep layer forcing/synoptic
scale lift will spread across the mississippi valley during the
day Sunday, allowing for the organization of an intense
complex/line of thunderstorms to spread eastward from ar/la into
ms during the day Sunday. A rather strong low level jet still
looks to develop across our forecast area ahead of the upper level
storm system Sunday, especially along and west of i-65 where 40-55
knots of 850 mb southerly flow is expected. Scattered to numerous
showers and storms should develop over much of the area ahead of
the main line to our west during the day Sunday, with the best
coverage along and west of the i-65 corridor. There are still some
timing differences noted in the operational medium range guidance,
but it generally appears that the main complex of showers and
thunderstorms should continue to advance eastward across our
forecast area Sunday evening into late Sunday night, before
progressing east of our area for the most part by late Monday
morning. The combination of the strong low level jet, favorable
0-6 km shear, up to around 1000-1500 j/kg of mlcape, and 0-1km srh
values up to 200-300 m2/s2 will be supportive of severe storms,
with all modes possible. Right now severe potential looks most
favored along and west of i-65 where shear/instability parameters
are most coincident, and this is where the latest day 4 outlook
from SPC highlights a 15% severe risk. Would not be surprised to
see this risk level increase with time and will continue to
monitor closely. Heavy rainfall and localized flash flooding may
become a concern as precipitable water values rise between 1.75"
and 2.25", which is very impressive. Rainfall amounts between 2-4"
with locally higher totals will certainly be possible with this
event, and will also mention potential heavy rain/flooding
concerns in the hwo Sunday into Sunday night. Drier zonal flow is
anticipated Monday into Tuesday. However, yet another round of
showers and storms returns Wednesday into Wednesday night as the
next system moves across the region. /21
marine... Southerly winds will decrease today as a cold front stalls
over northern portions of marine area. Winds will increase again
along with building seas this weekend ahead of another approaching
cold front. This front is expected to move across the marine area
Sunday night into early Monday. /13

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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.
