short term today through Thursday ...
short term forecast continues to be relatively straight forward and
summed up in a single word: wet. But there does seem to be an end in
sight in time for the weekend.
Models continue to show deepening upper level flow over the lower
mississippi valley that will lift through the tennessee valley
through late Thursday. The combination of anomalously high
precipitable water, strong forcing, and enhanced isentropic lift
will support a prolonged period of moderate to heavy rainfall
through Thursday, particularly this evening and overnight. Main
concern will be the flooding potential, with limited instability
keeping the severe storm threat non-existent.
For now, the heaviest forecast rainfall amounts run northeast across
the state, stretching from the greater columbus area through athens.
In this wide swath, 1.5 to 2.5 inches are forecast, with the
majority of it occurring between 7 pm tonight and early Thursday
morning. The highest forecast rainfall amounts are east of atlanta,
north of i-20 and south of i-85 (in the athens area), where rainfall
amounts of 2.5" or more will be common.
The prolonged rainfall observed over the last several days has kept
soils saturated, with local creeks and rivers at normal to well
above normal levels. As rainfall continues to accumulated, the
ability of rivers to handle the increased runoff is suppressed and
could quickly result in flash flooding. The flash flood watch
continues for a large majority of north and central georgia through
Near the end of the period, cold air advection will allow
temperatures to cool quickly Thursday night. There is a small
possibility of some mixed precip in the higher elevations just
beyond the valid period and into the extended forecast.
long term Thursday night through Tuesday ...
short wave moving rapidly through the oh valley Thursday night
could spread some cloudiness into our northern counties. The issue
is whether or not there will be enough moisture to produce
measurable precipitation. Dynamics look fairly strong into our far
north... So have continued with low pops for the 00z to 06z period
Friday. Rw- or sw- still look possible with little or no
accumulation. The next shift can revisit this for the afternoon
forecast. After that... The remainder of the long term looks dry
with mostly zonal flow aloft. A front pushes through ga on Monday
but GFS and ECMWF both show moisture decreasing as the front moves
south. So have included no pops for Monday. Temperatures should
moderate through the period.
ifr CIGS will persist through the period, with brief stints of|
MVFR possible. Light rain will continue off an on through the day.
Winds have shifted to the ne, and expect ne-se winds through
sunrise Thursday before shifting back to the nw. Speeds will
increase to 9-12kt by late morning, with gusts to 18-21kt
persisting into the evening hours. Cig improvement expected
through the day tomorrow as the rain ends, with MVFR by mid to

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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 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.
