short term /tonight through Monday night/...

cold front remains along the mid mississippi river valley while a
warm front stretches across the great lakes to the middle atlantic.

This means that the cwfa remains firmly in the warm sector.

Scattered showers have developed across portions of northern ga this
afternoon. Do expect this trend to continue during the peak heating
hours of the afternoon. There is some surface instability for storms
to work with, but lapse rates and shear remain fairly weak. A few
strong storms are possible, but severe weather is not anticipated at
this time.

A frontal boundary begins to push east of the mississippi river by
late Monday afternoon. With the cwfa in the warm sector with good
southerly flow, temps will remain above normal. With the available
low level moisture, scattered showers and a few thunderstorms remain
possible, mainly during the afternoon hours. There is a little more
support for storms tomorrow afternoon as a shortwave moves east in
the flow, helping to steepen lapse rates. There will also be a few
more hundred joules of CAPE around for the surface instability.

Once again, a few strong storms are possible.

Patchy fog will be possible overnight, especially where it rains.

long term /Tuesday through Sunday/...

Tuesday, on the back-side of a low pressure system/upper level wave,
a remnant surface boundary may result in just enough lift and low
lvl convergence to support a few showers/isolated storms. Otherwise,
upper level ridging will build across the SE region with a brief
period of rain/storm-free weather Tuesday evening into the first
part of Wednesday.

A significant storm system will move over the southern/central
plains Wednesday. Medium-range models showing some convective
development possible along that remnant stationary boundary that
begins to orient itself NW to SE from north alabama to south
georgia. Most areas will likely remain dry and warm with MAX temps
expected to reach the 80s for many locations.

The unseasonably warm air will set the stage for potential severe
weather sometime Thursday into Friday, as the aforementioned central
and southern plains storm system moves toward the mid mississippi
valley/upper midwest. Southern stream energy will interact with a
warm/unstable and moderate-shear environment to support strong to
severe thunderstorms. Too early to say how severe at this point,
especially given model inconsistencies with the exact track and
positioning of this system -- but safe to say the broader-scale
synoptic pattern is setting up for a potentially active end to the
work week across the deep south.

00z update...

cu field dissipating although there could remain sct060 through
the night. An ifr/MVFR cloud field is expected to develop along
the gulf coast and spread northeast into the forecast area late
tonight with CIGS going to either ifr/MVFR. CIGS will becomeVFR
with mixing by late morning Monday and into the afternoon.

Scattered showers and isolated tsra are expected to develop Monday
afternoon, but mainly across north ga. Winds will become light and
variable tonight, then southwest 10 to 15 kts by late Monday
morning.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
