Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Near term today-tonight
Today... Another surface trof will push across the SE u.S. Just
north of the region, but will not be as strong as yesterday so
west to northwest surface winds will be sustained in the 10-15 mph
with peak gusts in the 20-25 mph range. Skies will remain sunny
with MAX temps close to climo values in the lower to middle 70s.
Tonight... Trof pushes offshore NE of the region while next high
pressure center builds NW of the region. Cool and dry northwest
steering flow will weaken through the night and with clear skies
expect below normal temps in the 40s area-wide, with some upper
30s possible in normally colder inland locations.
Short term sat-sun
Mid upper level shortwave ridge initially over the ms valley will
shift quickly ewd over the weekend and push offshore by Sun night.
Broad sfc high pressure over the ohio valley will move southeast and
push offshore of the east coast. This will result in fairly
light northeast to east flow on Saturday, then east and southeast
increased winds on Sunday. A continuation of dry conditions
with near seasonal afternoon temps and cooler than normal nighttime
lows for Saturday. Skies to be mostly sunny with just a few high
clouds. Expected southeast flow on Sunday will result in warmer aftn
temps with dew-points responding into the mid 50s along the coastal
areas. Again, mostly sunny with a few cumulus and some high clouds
at times. The next frontal system will move to the tn valley to
southeast tx late Sunday night. Expecting a light southerly flow on
sun night with a gradual increase in low level moisture and possible
few stratus clouds and localized fog late in the night. Low
temperatures will be held in the 50s overnight.
Long term mon-thu
Monday... Southwest low level flow expected ahead of the approaching
cold front with temperatures warming to the upper 70s and possibly
lower 80s. Fairly weak dynamics aloft and deeper moisture north of
the area will result in low pops on Monday with the best chance of
showers or an isolated t-storm over southeast ga as the front nears
the area. Cold front looks to push through our forecast area quickly
Monday night as a sfc wave forms over sc area and pushes southeast
and offshore. Expect a low chance of showers during this time frame.
Tuesday-Tuesday night, a surge of north-northeast winds likely to
develop behind the front ushering cool moist air and chance of
showers due to strong convergence. Highs on Tuesday well into the
70s SRN zones but may be held to upper 60s to lower 70s northern
Wednesday, a lower chance of showers and mainly along the coastal
areas as drier air may filter in from the north and northeast as low
pressure along the front scoots well offshore over the WRN atlantic.
Temperatures cooler in the 60s to near 70. Breezy-windy northeast
flow expected due to a strong sfc high pressure system located to
our north over mid atlantic area.
Wednesday night into Thursday, sfc high pressure ridge will drift
into the region from the north resulting in weaker pressure gradient
and mostly clear to partly cloudy skies. Slightly warmer Thursday
with highs into the lower and mid 70s, slightly cooler at the coast.
Vfr with skc and some w-nw winds pushing back to 10g15 knots after
14z to 15z time frame.
Small craft advisory conds offshore and scec nearshore with w-nw
winds 15-25 knots early this morning and seas 4-8 ft and will see
slow decrease in winds seas through the day with SCA flags ending
by late this morning. As high pressure builds north of the waters
this weekend winds become northeast Saturday then southeast on
Sunday generally at speeds close to 10-15 knots with seas coming
down to 2-4 ft. Winds become southwest ahead of the next front on
Monday, then out of the northwest-north on Tuesday following the
next frontal system with SCA possible.
Rip currents: despite the offshore flow today, easterly swells
still running close to 2 ft at the local buoys will still support
a moderate risk today, then likely down to a low risk on Saturday.
Critically low rh again today but average wind speeds will likely
stay below 15 mph area-wide so no red flag warnings. Dispersion
values will be a bit elevated in a few areas. Saturday, critically
low rh values again mainly inland areas and winds will likely again
be less than 15 mph. Sunday, min rh values not as low due to
gradual increase in low level moisture.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
