Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

High pressure will build into our region from the north through
Thursday, then drift east and weaken on Friday.
Near term through tonight
As of 905 pm Wednesday...
surface high pressure continues to build into the area from the
north this evening, with the surface front that moved through the
area this morning now settling to the south and east of central nc.
This will allow for a dry night, with low temps generally falling
into the 60s areawide, with perhaps a few readings dropping to
around 60 degrees. Low temps will be the warmest across far southern
portions of the area, where we could see a period of low stratus
develop early Thursday morning, given the main low level frontal zone
still resides nearby across sc.
Short term Thursday through Thursday night
As of 220 pm Wednesday...
for Thursday, a quiet day is expected with no precipitation in the
forecast. In fact, much of the day should be mostly sunny. Winds
will obtain a more easterly component during the afternoon and
increasing clouds, especially in the western portion of the forecast
area are likely. Temperatures are expected to be much like today as
well with upper 80s to low 90s during the day and lows in the 65 to
70 degree range.
Long term Friday through Tuesday
As of 315 pm Wednesday...
the long term will be characterized by a rather active pattern
with precipitation in the forecast for almost the entire period
and temperatures near normal for this time of year. The latest
runs of the GEFS and geps continue to show below normal height
anomalies across the area this weekend and near normal heights
for the following work week.
On Friday an upper level shortwave embedded in the longwave
pattern will be diving southeast across the ohio valley.
Simultaneously a mid-level ridge will be amplifying over texas.
Friday evening a piece of energy will pull northeast out of the
gulf of mexico wrapping up with the upper level low over ohio.
The cmc, ecmwf, and GFS all show this in one form or another.
The general consensus is for surface cyclogenesis to occur near
the southeast north carolina coastline Friday evening. Models
are all trying to show higher QPF totals along the PVA maximum|
with very little in the way of QPF in between the surface low
and upper level low. Looking at the rh fields this makes sense
given the dry air being wrapped into the upper level low. For
now have kept pops highest towards the coastline and across the
western zones with a bimodal QPF footprint.
During the day Saturday the stacked upper level low will become
detached from the main flow and drift southeast. Saturday night
into Sunday, global models are hinting at a wedge of pva
rotating around the upper level low and swinging through the
region. Pwats by this time will surge to around 1.9" (2"
according to the GFS and 1.8" according to the ecmwf).
Instability wise, mid-level lapse rates will be more than
sufficient given the proximity of the cold core low. Due to the
instability, moisture, and lift have raised pops Saturday
evening into Sunday.
Monday and Tuesday the upper level low that was over the ohio
valley will be squeezed southwest between and amplifying mid-
level ridge and a retrograding low moving in from the east. With
the forecast area sitting in between these two systems and
pwats remaining around 2.00" the chance of showers and
thunderstorms will continue. For now have kept the pops at
chance, but this will likely have to be raised if this trend
Aviation 00z Thursday through Monday

there is a high probability ofVFR conditions through thu, under the
influence of dry high pressure that will continue to ridge swd into
nc, as it migrates from the great lakes to the middle atlantic and
northeast states. One exception will be a risk of fog and stratus
over far SRN and ERN nc, and more so over sc, late tonight-early thu
morning, in closer proximity to a frontal zone and more abundant low
Outlook: that same front will retreat nwd as a warm front into ern
and cntl nc late Fri through sat. The retreat of the front and
accompanying influx of richer low level moisture will increase the
probability of low stratus over SRN nc (including fay) early fri,
then area-wide Fri night-early sat. Mainly afternoon and early
nighttime showers and storms will also accompany the front during
that time, with that threat then expected to continue amidst a
moist, unstable, and perturbed pattern through early to mid next

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.
