UPDATE FOR AVIATION.
PREV DISCUSSION . /Issued 335 AM EDT Mon Mar 30 2020/
SHORT TERM /Today through Tuesday/ . The main concern this short term period will be Tuesday and possible severe weather over central GA.
Surface low pressure is forecast to move across the lower MS valley tonight and along a warm front over the central to S GA area on Tuesday.
There will be a rather sharp gradient of instability associated with the warm front and well as low level shear. This will lead to a period of severe thunderstorm potential in the afternoon. SPC has highlighted central GA with a marginal to slight risk with the southern portion of central GA as the slight risk area. The main hazards will be damaging winds and a few tornadoes. Hail will also be possible.
Otherwise, just high clouds moving across the area today.
Forecast high temperatures are running near to as much as 10 degrees above normal across the area today and well below normal over N GA and plus or minus 4-6 degrees of normal over central GA on Tuesday. Forecast low temperatures are running 6-13 degrees above normal for tonight. Overall confidence is medium.
LONG TERM /Tuesday Night through Sunday/ . Low pressure should be moving offshore the GA/SC coast at the beginning of the period. Widespread showers and thunderstorms are progged to be ending from west to east. The potential for strong to an isolated severe storm should be limited to right around 00Z. This is shown fairly well by the hi-res models. However, scattered upslope showers will continue to be possible across the NE GA mtns overnight. By Wednesday, high pressure will begin building in from the west.
High pressure will be the dominant weather feature through the end of the week, but the ridge will begin to move offshore Friday night. Meanwhile, a weak frontal boundary will begin to approach the Mississippi River Valley. This boundary will slowly move east through the weekend, with the chances for showers increasing by Saturday.
FIRE WEATHER . Min humidities of 20 to 35 percent can be expected across the area today with most durations less than 4 hours. The area most likely to see humidities of 25 percent or less will be the SAV river valley and central GA. Winds are expected to be around 10 mph or less.
AVIATION. 12Z Update . VFR conditions with mid-high clouds/ceilings into tonight. Surface winds WNW-NNW 10 kts or less.
//ATL Confidence . 12Z Update . High confidence for all elements into tonight.

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 numerous 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.
