What forecasters said that day
The local office's own words before this flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before this flood watch went out at Feb 21, 1:15 PM EST, 59 minutes earlier.
Area forecast discussion, Feb 21, 1:15 PM EST, 59 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 115 PM EST Thu Feb 21 2019 .UPDATE... 18z Aviation update below. Baker && .PREV DISCUSSION... /Issued 928 AM EST Thu Feb 21 2019/ UPDATE... Have some lingering quarter mile vsbys with fog this morning so covered with a Special Weather Statement on patchy dense through 11 AM. Also given the cloud/precip trends in parts of the north have kept afternoon temps a bit lower and slowed morning warm up trends as well. Still expecting some increased shower/isolated TS development this afternoon in parts of central GA then propagating northeastward into portions of north GA. For now will continue to hold onto Flash Flood Watch through this evening so that we can monitor afternoon trends in coverage. Previous discussion follows... Baker && .SHORT TERM /Today through Friday/... Band of showers and isolated tstorms has becoming stationary. This area of showers will begin moving northward as the next short wave approaches from the west. This next short wave will bring an increase in moisture across west central GA this afternoon and then lift into north GA tonight before exiting. The stationary front across central GA will hold into this evening, then as the surface high builds into the northeast U.S. tonight, a backdoor front will move across the CWA Friday wedging the CWA. There will still be plenty of isentropic lift over the wedge and this will keep chances of rain continuing, although amounts on Friday will be a half inch or less. Dense fog has developed across parts of central GA and this will continue into mid morning. Will therefore continue the Dense Fog Advisory for this morning. Rainfall amounts today should remain below 1 inch across the CWA, however with the ground already saturated, it will not take much rainfall to push a creek or river into flood, especially with a thunderstorm that could produce higher amounts. Will therefore continue the Flash Flood Watch for today. 17 && .LONG TERM /Friday Night through Wednesday/... The long term period begins with a wedge setting in to NE Georgia in addition to a stalled front just north of the area. With southwesterly flow pushing moisture into the area, chances for showers will continue through Saturday, with the highest chances across northern Georgia. High PWs and instability will continue the potential for periods of heavy rain and isolated thunderstorms across the area. With multiple rivers across northern Georgia already in flood, concerns for river flooding and flash flooding will continue as these rounds of precipitation impact the area, especially across portions of northern Georgia. Chances for showers and thunderstorms increase across the entire area for late Saturday/Sunday as a cold front pushes through the area on Sunday. QPF totals are currently around half and inch to an inch with the highest totals across northern GA. With already saturated soils across much of northern Georgia concerns for river flooding and flash flooding will continue. After this system clears the area late Sunday, we should see some drier weather on Monday and for some areas part of Tuesday as high pressure pushes into the area. Models then show a wave moving north from the gulf into the area on late Tuesday into Wednesday, but models differ on northward extent as well timing of the moisture across the area. At this point have only included slight chance pops across the area. Temperatures through the weekend are expected to be just above average in the 60s and 70s, aside from those within the wedge on Saturday where highs are expected to be in the 50s. After the weekend system, high temperatures are expected to be closer to seasonal norms. Reaves && .AVIATION... 18Z Update... Mainly LIFR cigs lingering across the sites (scattered higher near KCSG), and KATL has been holding close to 300 ft. LIFR/VLIFR vsbys with fog in the north should improve to MVFR or VFR this afternoon as a warm front lifts northward. Shower and TS chances increase after 19/20z this afternoon then focus shifting to the northern sites later. There is a good chance some dense fog will return to the sites early Friday morning so have 1/4SM with again LIFR cigs from 09z to 15z. Winds initially light VRB for most sites (could stay light east for KATL) then light NE to SE overnight. //ATL Confidence...18Z Update... Medium on TS and SHRA coverage/timing this afternoon/evening. Medium on extent of possible dense fog Friday AM. High on all else. Baker && .PRELIMINARY POINT TEMPS/POPS...

Areas of patchy dense fog will linger across the area through late morning. Showers and isolated thunderstorms are expected to continue to impact the area through this afternoon and evening. The main hazards with any storm will be gusty winds and heavy rainfall. The Flash Flood Watch continues until this evening for most of North Georgia including the Atlanta metro, where 1 to 2 with locally higher amounts are possible. As a result of multiple periods with heavy rainfall, nearly all the rain that will fall will be converted to runoff and some localized flooding of creeks and streams may be possible across portions of northern Georgia. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... An increased threat for river and stream flooding will continue through the week and weekend as rain falls over saturated grounds. Localized flash flooding will also be possible, especially over the complex terrain of north Georgia. Make sure to stay tuned to the latest forecasts and updates each day for any changes to the forecast. In addition, there is a chance of thunderstorms on Saturday and Sunday .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed through tonight.
