Area Forecast Discussion National Weather Service Peachtree City GA 854 PM EST Tue Jan 28 2020
UPDATE. High pressure will continue across the area tonight. Mid and high level cloudiness will continue from west to east overnight as the next system begins to approach from the west. Grids/forecast are in pretty good shape and will only make some minor changes to the hourly/temp and sky grids.

SHORT TERM /Tonight through Wednesday Night/ .
Not a bad day at all by late January standards as a large ridge of high pressure extends from the northern plains through the Tennessee Valley and into the local area. Full sun today has allowed temps to reach the mid to upper 50s for most locations with even some lower 60s noted across Central GA. A look to the west however on the regional satellite view indicates the next storm system of consequence to begin initial impacts tomorrow.
First, for tonight, approaching trough will provide for some increasing upper diffluence through the morning hours. Meanwhile, cool dome of high pressure at the surface tries its best to hang on, especially across the NE portions. Question continues to be whether there will be a juxtaposition of these 2 features to create a brief period of freezing rain Wed morning. At this time, I have it as no in the grids with temps remaining just above freezing and precip arriving just after daybreak for NE portions. This will need to be monitored closely though by evening and overnight shift.
Much more confident on rain developing for most of the area late Wed afternoon. In fact, feel most of the models and especially the ensemble means are underplaying pop potential for Central GA zones. Sure, its not likely to be heavy QPF by any stretch but combination of DPVA and isentropic upglide should be more than enough to warrant categorical pops for a good portion of the area south of I20.
LONG TERM /Thursday through Tuesday/ .
The progressive pattern at the upper level continues as the extended period begins. By Thursday morning, the upper-level trough and associated surface low over the northern Gulf of Mexico will be moving quickly eastward away from the forecast area and into the Atlantic Ocean. Precipitation associated with this system is expected to come to an end during the morning hours on Thursday. Meanwhile, upper-level ridging will build in over the southeastern CONUS and persist through the remainder of the day Thursday. As a result, a brief period of clearing conditions will occur until the next system brings the next round of precipitation to north and central Georgia.
On Friday, the upper level ridge pushes eastward towards the Atlantic coast and another trough approaches the forecast area from the west. Southwesterly upper level flow on the backside of the ridge will contribute to moisture overspreading the forecast area, leading to increasing cloud cover by early Friday morning followed by showers arriving by Friday afternoon. High pressure is furthermore expected to build down the Appalachians during the day. Latest guidance is in good agreement on heaviest precipitation spreading into the area Friday afternoon and exiting Saturday morning, although some uncertainty still exists on the northward extent of the precipitation. Have trended PoPs up on Friday and early Saturday, with highest chances anticipated across central Georgia. It is possible to see some lingering moisture and light precipitation on the backside of the system early Sunday morning after the system exits the area. There is a chance for wintry precipitation over the higher elevations of northeast Georgia on Friday, Saturday, and Sunday mornings, although no more than a trace of snow and no impacts anticipated at this time.
Strong upper level ridge and surface high will build in across the southeastern CONUS during the early parts of next week. High temperatures through the end of the week are expected to run near to slightly below climatological normals, with highs primarily ranging from the upper 40s in far north Georgia to the upper 50s in central Georgia. Low temperatures, on the other hand, are expected to be about 4-8 degrees above normal each morning. Low temperatures will be in the upper 30s to low 40s across much of the area, with the exception of the higher elevations of the far northeast, where lows will drop to near freezing each morning. Upper level ridge will lead to increasing temperatures at the end of the period.
AVIATION . 00Z Update . Mid and upper level cloudiness will be on the increase overnight. Cigs will remain well above 10kft through mid morning tomorrow. Cigs will begin to lower during the early afternoon hours, but should still remain above 3.5kft. Winds will be the main forecast issue. Speeds will go light overnight (less than 5kt) and try to shift to the NE. With speeds so light, the direction could flip flop around due north until mid morning on Wednesday.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
