Marine Weather and Tides
Cartersville, GA

Version 3.4
What's New / NOTES
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

high pressure will continue across the area tonight. In addition,
mid and high level cloudiness will also continue to overspread the
cwfa. Temperatures will not be as cold as previous nights, with
values mostly in the 40s outside of the higher elevations. No
changes needed to the short term portion of the forecast, other
than to tweak the hourly temp dew grids.

Did go ahead and make one minor change to the Sunday night period.

With temps near slightly above freezing and a chance for precip,
have tweaked the ptype to rain or freezing rain.

short term tonight through Saturday night ...

swaths of mid level moisture allowing for continued alto deck for
parts of the north and west in the near term and into Saturday.

Increasing chance in the far north overnight for some isolated
showers but overall weak forcing. Thinking should stay dry fcst for
majority of CWA through tomorrow and then the greater precip chances
come in for Saturday night especially when some overrunning ramps up
as a strong classical cad wedge builds in from the ne. Cannot rule
out some isolated thunder potential for Saturday afternoon in the
far north given some guidance, though feel not enough consensus in
if a 700 mb inversion is capping things.

Temps should be near climo norms tonight and ramp up nicely for a
pleasant Saturday with most locations in the low to mid 70s.

Saturday night will have a rather large gradient with aforementioned
wedge building in from the NE and some pretty high lows for other
areas mainly in central ga with strong southerly advection continued
outside the wedge.

long term Sunday through Friday ...

while a weak mid level ridge will be building into the area from the
west... The lower levels will feature a quickly moving strong wedge
down the leeward side of the appalachian mountains as we begin the
long term forecast period. As the wedge quickly builds in... It will
push a weak cold front southwards across the cwa. Additional lower
level convergence supplied by the wedge frontal boundary as it
merges with the cold front will allow for enough lift to generate
scattered showers across most of the area... Gradually shifting from
north to south thru the day. Looks like enough instability albeit
weak will be available mainly across central georgia for isolated
chances for thunder.

Monday looks like a raw day across the area as wedge continues to
build in as a 1040+mb parent high centers itself across the
northeast... Essentially setting up classical cad conditions. Winds
will be breezy and most locations will be lucky to reach 50 degrees.

In addition... Despite continued ridging in the mid and upper
levels... Plenty of shortwave energy will traverse atop the ridge to
aid in synoptic scale lift and allowing for a continued chance for
at least isolated to scattered showers and possibly drizzle. Will
need to watch the potential for light sleet snow showers possibly
transitioning to light freezing rain across northeast mountainous
terrain early Monday as 12z model sounding data suggests saturated
lower level profile amidst temps near freezing.

More divergence exists between ECMWF and GFS going into
Wednesday... But trended more towards the GFS solution as wedge
continues and even tho mid level ridge continues to amplify and shun
shortwave activity further north... Saturated lower level profiles
suggest drizzle is likely for most of the day.

Could dry out some briefly on Wednesday as the lower level
ridge wedge loosens its grip across the region. However... The next
system will be approaching if not moving into the area from the
west. This could make for more widespread... Heavier rainfall across
parts of the area thru the rest of the extended. At least temps will
rebound back into the 70s.


06z update...

continue to see mid to high level clouds stream across the
region affecting most of the terminals. There are some light
returns on radar but not reaching the ground and this trend should
continue today. Winds have shifted but are very light at atl and
should see a return to SW by mid morning and gusting by
afternoon. Gradual lowering of the CIGS into overnight Sat with
some MVFR possible by 06z along with vcsh mention.

Atl confidence... 06z update...

High on remaining elements.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
