12z issuance...VFR conditions will be followed by ifr MVFR
ceilings advancing into much of the area from the west this
morning, thenVFR conditions return by this afternoon. Sparse
patches of light rain sprinkles over much of the area will move
off to the east this morning leaving dry conditions. North to
northwest winds at 5 to 10 knots area expected today then calm or
a light northerly flow follows for tonight. 29
prev discussion... Issued 410 am cst Tue nov 20 2018
near term now through Tuesday night ... An upper trof over the
eastern states weakens through tonight as a vigorous series of
embedded shortwaves eject off into the western atlantic. A surface
low currently located near the d.C. Area has brought a weak cold
front to near the i-65 corridor within the forecast area. The cold
front continues eastward through the remainder of the forecast area
this morning followed by a dome of surface high pressure building
from the southern plains into the region. A combination of the
series of shortwaves and frontal boundary progressing through the
area will bring isolated patches of rain to much of the area this
morning, otherwise dry conditions are expected through tonight.

Highs today range from around 60 inland to the lower 60s near the
coast. Lows tonight range from the mid 30s inland to around 40
closer to the coast. 29
short term Wednesday through Thursday night ... A nearly flat
mid level flow sets up over the southeast Wednesday with surface
high pressure positioned from the mid-atlantic to east tx. Deep
layer environmental moisture is limited Wednesday and with the
position of the synoptic scale low level high, no rain in the
forecast Wednesday. Next southern stream impulse aloft ejects
quickly eastward over tx Wednesday and begins to deamplify as it
crosses the gulf thanksgiving day. The deeper moisture and ascent
associated with this system looks to be more focused out over the
coastal waters where forecasters maintain a small chance pop.

Portions of the coast could see a passing shower, but measurable
rain looks to be light. North of the coast, it appears areas look
to escape rain Thursday being under more control of southern
states high pressure.

Highs and lows well below seasonal normals to open up the latter
end of the month of november. 10
long term Friday through Monday ... A more vigorous upper level
storm system moves quickly east out of the southern plains Friday
advancing over the ms river valley Friday evening. Deep layer
moisture makes a quick return ahead of the approaching storm
system. At same time, ascent becomes maximized into the afternoon
and evening as a zone of upper level divergence moves over the
area. This results in likely to categorical pops. As far as
convection, this will be highly dependent on any northward
progress of a warm front near the coast. At this time, it appears
a surface wedge of high pressure nosing in from the northeast
Friday will be strong enough to keep a more stable boundary layer
in place over much of the area with the warm front any warm
sector suppressed closer to the coast or just offshore. The
latest GFS and ECMWF are now in much better agreement on showing
frontal wave of surface low pressure tracking east and skirting
the central gulf coast by Friday night which supports little
northward advance of the warm front. As far as instability,
guidance continues to advertise this as being very weak, even
offshore. There still could be more instability than what the
models advertise, but do not have enough confidence to mention
more than a slight chance of thunder mixed in with the predominant
mode of showers Friday and Friday night. Event total rains could
add up to between 1 and 2 inches. Rip current risk is favored to
increase Thursday and Friday over area beaches. Daily highs
Friday look to be coolest over the interior and remaining well
below climatology.

Late week system moves east and scours out moisture by Saturday
resulting in no rain. Rain chances return Sunday as better
agreement is seen in guidance showing strong cold front making
passage late in the weekend. Highs moderate Saturday and Sunday,
then show a much lower trend Monday. 10
marine... Light to moderate offshore winds prevail through Wednesday
then become easterly on Thursday. Small craft may need to exercise
caution well offshore late this evening to shortly after midnight as
the offshore flow temporarily increases somewhat. A moderate to
strong southeast flow develops on Friday then switches to the
northwest Friday night as a low pressure system moves across the
area. A small craft advisory may be required for much of the area
Friday and Friday night. The offshore flow subsides on Saturday.

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.
