short term tonight through Friday night ...

quiet fcst continues on with ridge in control of regime and
prevailing dry mostly clear conditions. While center of sfc high is
close to north ga, our resultant winds should be light and variable
to calm overnight. Radiational cooling should be strong but not
result in as low of morning temps (staying in 40s for most areas).

Friday should have some amplifying upper ridging that translates the
sfc high a bit farther northeast, so while winds tomorrow should
still be light, they should have more of a east component. Highs
should moderate to about 5 deg above climo, with most areas in the
upper 70s to near 80.

long term Saturday through Thursday ...

high pressure ridging will continue to influence the forecast area
to begin the extended period, which will lead to the continuation of
benign and seasonal conditions. Cloud coverage will begin to increase
on Saturday as the upper level ridge moves off to the east and is
replaced by upper level southwesterly flow. More moisture is then
expected in the area on Sunday due to return flow off the gulf of
mexico, which will lead to an increase in pops, in the 20 to 30
percent range in the afternoon.

Medium-range models are then fairly consistent in regards to the
passage of a cold frontal system through the forecast area early
next week. Widespread heavy rain, with pops in the 60 to 80
percent range, and the potential for at least isolated strong to
severe thunderstorms can be expected ahead of this front. It is
most likely that these conditions will be observed on on Monday
night and into Tuesday. However, model inconsistencies still exist
concerning the orientation, timing, and strength of this system.

Strong cold air advection associated with another shortwave, along
with the cooler air already in place behind the passage of the
front, could contribute to significantly below normal temperatures
to the area in the later parts of the week.

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.
