Marine Weather and Tides
Columbia, SC

Version 3.4
What's New / NOTES
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.

Synopsis
Weak surface trough will remain across the region, however a
building upper level ridge aloft through midweek will limit
afternoon thunderstorms and result in warmer than normal
temperatures through most of the week. Increasing moisture late
in the week along with the ridge weakening may result in an
increase in scattered afternoon thunderstorms late in the week.

Near term until 7 am this morning
Weak high pressure over the region with only a few passing high
clouds. Temperatures slowly falling through the 70s.

Short term 7 am this morning through 6 pm Tuesday
High pressure aloft over the southeast u.S. Will lead to hazy, hot,
and humid conditions Monday through Wednesday. High temperatures
will be in the upper 90s to around 100 degrees with dewpoints in the
lower 70s. This could lead to the issuance of heat advisories
Tuesday and Wednesday with heat indices approaching 110 degrees.

Isolated afternoon and evening thunderstorms may be possible
primarily on Wednesday due to the extreme heat.

Long term Tuesday night through Sunday
An unseasonably strong upper trough is forecast to swing across new
england later this week and push a backdoor cold front into
virginia north carolina per the ec. The GFS pushes this front
farther into the carolinas. 500 mb height falls and the proximity of
the front will lead to slight cooling trend and increase in
convective activity Thursday into Friday.

The upper trough moves into the canadian maritimes next weekend and
the pattern develops into a flat ridge over the gulf states and a
progressive zonal flow across the midwest and mid atlantic.

Disturbances in the flow aloft should result in scattered mainly
diurnal convection.

Aviation 06z Monday through Friday
Generally expectingVFR conditions through the forecast period.

Generally clear skies overnight with the possibility of some
stratus or fog development along the coastal plain and
approaching ogb 08z-12z. OtherwiseVFR conditions expected
elsewhere. Light and varible to calm winds through dawn will
then increase to around 5 to 7 knots from the southwest after
15z. Chance for convection will be lower this afternoon given
upper level ridging and subsidence over the area, but few to
scattered cumulus are again expected.

Extended aviation outlook... Restrictions possible each day in
early morning fog and isolated afternoon and evening
thunderstorms.

Cae watches warnings advisories
Ga... None.

Sc... None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code.

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.
