Update
Deep closed h5 low is beginning to lift from northern mexico
towards the texas big bend. Resultant downstream ridge across the
southeast will keep the area dry and mild today with some high
clouds of pacific origin passing by throughout the day. Sfc is
dominated by high pressure. High temps in the 50s expected
throughout the cwa.

Inherited forecast is largely on track this morning and have made
minimal changes.

short term today through Sunday ...

quiet weather day in store today as dry surface high pressure
moves across the area.

The next system for Sunday will be a weakening short wave that
is forecast to have deep moisture associated and no instability.

It will affect N ga the most with light rain chances starting
close to mid morning for the far NW then the rest of N ga through
the afternoon.

Forecast high temperatures are running near to slightly below
normal today and 3-5 degrees above normal for Sunday.

Forecast low temperatures are running close to normal tonight.

Overall confidence is high.

long term Sunday night through Friday ...

still looking for a cutoff low to develop over the 4 corners
region as the long term period begins providing a pattern for most
of the period that resembles anything but la nina. Upper level jet
will be a mainstay over the tennessee valley and providing energy
to the local area until actual upper low eventually kicks out and
provides its own dynamics.

At the same time, surface high will remain largely offshore
allowing for ample low level moisture to interact with these upper
level features. This all begins Sunday night into Monday when
precipitable water climbs to 1.75 inches over central ga and jet
impulses along with isentropic influences lead to the development
of likely pops. Could be that these need to be upped to
categorical with time but ECMWF not quite as aggressive initially
as GFS so will hold off.

Area will be in and out of likely rain chances but mostly in until
shortwave ejects out of the plains and pushes through late
Wednesday. Models showing as high as 5 inches through the entire
period but QPF should be spread out enough to preclude any
significant flood concerns. Otherwise, will continue to indicate
periods of thunder in the grids as well trying to match up with
individual impulses to move through.

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.
