What forecasters said that day
The local office's own words before this flash 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 flash flood watch went out at Mar 3, 1:07 PM EST, 1 hour 26 minutes earlier.
Area forecast discussion, Mar 3, 1:07 PM EST, 1 hour 26 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 107 PM EST Tue Mar 3 2020 .PREV DISCUSSION... /Issued 651 AM EST Tue Mar 3 2020/ UPDATED FOR 18Z AVIATION. .SHORT TERM /Today through Wednesday/... Persistent southerly low-level flow over much of the southeastern CONUS is allowing for continued deep moisture over the forecast area. Dewpoints in the upper 50s to low 60s and precipitable water values between 1.25" and 1.5" are in place across north and central Georgia as a result of this moisture. With a surface warm front moving northeastward out of the area, residual isolated showers, low cloud ceilings, and patchy fog are in place across north Georgia as the short term period begins. The relative break from showers early this morning will be short-lived before the next shortwave traversing the upper-level flow brings the next round of precipitation into the area later this morning and afternoon. At the surface, the cold front that has provided a focus for widespread precipitation will continue to move southeastward from the Ozarks towards north Georgia, and will progress into central Georgia this afternoon. This front will continue to provide a focus for widespread rain, with categorical PoPs entering north Georgia this morning and spreading southward into central Georgia during the afternoon hours. Widespread rain will lead to rainfall totals of up to an inch across the forecast area today. The warm and moist airmass in the area ahead of the front will allow for sufficient instability to support thunderstorms during the late morning and afternoon hours today, with SBCAPE values of 400-800 J/kg anticipated. Low-level wind shear of 30-35 kts and deep layer bulk shear of 55-65 kts is also expected in the area ahead of the cold front as it enters into central Georgia. 0-1km helicity values in the 150-200 m2/s2 range are possible ahead of the front, as well. With westerly bulk shear vectors oriented against the southerly flow, it is possible to see a supercellular mode of convection in portions of central Georgia during the afternoon today, in spite of only modest lapse rates of 5.5 - 6 C/km. Nonetheless, some strong to severe thunderstorms, capable of producing damaging wind gusts and a brief tornado, are possible during the afternoon. Another break in the precipitation is expected from Tuesday night and into Wednesday morning as the cold front pushes south of the forecast area. However, this break is also expected to be short- lived, as a surface low over the Gulf Coast will bring another round of heavy rain to the area during the daytime on Wednesday, primarily focused in central Georgia. Likely to categorical PoPs will spread northward first into central Georgia and then into north Georgia throughout the day on Wednesday, bringing additional rainfall amounts ranging from an inch in central Georgia to a quarter of an inch in the far northern tier. The cumulative rainfall over today and Wednesday will allow for an increasing threat for localized flooding concerns. Warm and moist air will contribute to warmer than average conditions today, with low temperatures in the 50s across the area are running 15-20 degrees above climatological normals and highs in the upper 60s and low 70s this afternoon will run 5-10 degrees above normal. Overnight lows tomorrow will range from the upper 40s in north Georgia to mid 50s in central Georgia. Overcast skies and the potential development of a CAD wedge on Wednesday afternoon could lead to cooler highs on Wednesday - mainly in the upper 50s to low 60s across the area. King .LONG TERM /Wednesday Night through Monday/... Like a broken record, heavy rainfall will be ongoing at the start of the extended Wed night across Central and S GA. One saving grace for severe potential into Thu will be the confluent 500mb flow over the Mid Atlantic states which typically allows for some wedging to occur and is suggested by models, albeit not strong. This combined with the southern stream system kicking out of the Arklatex at such a low latitude, the baroclinic zone along the Gulf will likely trap the instability and confine it to far southern GA and the Gulf coast which models suggest in addition to a surface low developing along the coast and tracking ENE south of our region. Regardless..analysis of the isentropic surfaces suggests strong isentropic lift aka upglide as the southern/main shortwave approaches. Both the 300k and 295k surfaces showing 100mb of lift from CSG to DZJ within a saturated layer and PW's increasing to 1 to 1.5 inches. So...expect a precip shield across Southern GA to lift Northward through the evening and overnight overtaking all of N GA by AM. Rainfall could get a bit heavy in the early Thu AM timeframe as a result. Main upper low ejects out during the day Thu so precip should end from west to east after 21z or so. Friday through Sunday...All hail a nice weekend! Trof dominates the eastern half of the country with surface ridging building in Friday behind the departing system...making Friday the windiest day of the weekend. Saturday and Sunday look pleasant with high pressure overhead..so light winds and clear skies will prevail. By Late Sunday, surface high shifts off the east coast and moisture begins to return with southerly flow ahead of another southern stream system. Rain chances return late Monday through Tuesday as the system passes through. ECMWF and GFS differ on this system and how it interacts with a northern stream wave. GFS would suggest a longer period of wetness lingering into late Wed, while the ECMWF exits the system a full 24 hours earlier. Confidence out on day 7 not all that great as a result. But hey...enjoy the weekend!! Stellman && .AVIATION... 18Z Update... Ceilings hovering in the MVFR range but will lift into the VFR range just before sunset. Will see MVFR ceilings move back in Tuesday a precip moves back in. Showers across the area are diminishing as the line moves a bit further south. should see a few more showers at the TAF sites this afternoon then tapper off just before sunset. Rain moves back in Tuesday afternoon. Wind will stay out of the W to NW. Wind speeds are in the 10-20kt range and will diminish to 10kt or less overnight and stay there through the period. //ATL Confidence...18Z Update...
