Area Forecast Discussion National Weather Service Peachtree City GA 213 PM EDT Mon Aug 19 2019 .PREV DISCUSSION... /Issued 1234 PM EDT Mon Aug 19 2019/ UPDATE... Have made minor updates to the forecast, but overall it is on track. Seeing some light returns on radar in a few isolated areas this afternoon, but really expect the coverage to increase after 2-3 pm. No additional updates are planned before the afternoon package. 31 PREV DISCUSSION... /Issued 750 AM EDT Mon Aug 19 2019/ UPDATE... Updated for the 12Z Aviation Discussion. PREV DISCUSSION... /Issued 413 AM EDT Mon Aug 19 2019/ SHORT TERM /Today through Tuesday/... To begin the short term period, the forecast area will be situated near a weak upper level trough positioned between a broad upper level ridge in place to the west of the forecast area over the Central Plains, and to the east of the area over the western Atlantic. The upper-level troughing is allowing for a northward advection of the deeper moisture, which will lead to a continued moistening of the airmass and an overall unsettled pattern through the period. PWATs of 1.3-1.6 inches across the area this morning will steadily increase to 1.7-2 inches by Tuesday afternoon. At the surface, a weak surface low in south Georgia will continue to slowly traverse northward into Georgia through the period. This overall pattern will allow for greater coverage of diurnally driven convection during the afternoon and evening on Monday and Tuesday, with primarily high-end chance to low-end likely PoPs expected across the area each day. Widespread severe weather is not anticipated on Monday and Tuesday, although it is possible that a few storms may become strong to marginally severe and could produce gusty winds and frequent lightning. With the increased moisture, there is a possibility that some of the stronger thunderstorms could produce locally heavy rainfall, as well. Forecast high temperatures are expected to remain above climatological normals on Monday. Especially along and north of the I-85 corridor where highs could range from 5-8 degrees warmer than average. Heat index values are anticipated to remain below Heat Advisory criteria, but will nonetheless reach near or just above 100 across much of the area on Monday, with the exception of the higher elevations in northeast Georgia. Increased sky coverage and convective coverage will contribute to slightly cooler temperatures and heat index values less than 100 on Tuesday. King LONG TERM /Tuesday Night through Sunday/... Diurnally driven scattered to numerous showers and thunderstorms will be the norm in the extended periods of the forecast. The area will remain situated in the weak upper trough between the ridge over the Plains and western Atlantic ridge. Moisture continues to slowly increase across the area through the end of the week which will will provide a boost each afternoon for convective development. By the end of the week, the models are showing a cold front pushing south out of the great lake state Thursday and into North GA Friday. The models show this frontal boundary stalling across the southeastern U.S. and keeping rain chances across the region through the end of the forecast period. Another weaker wave also pushes northeast out of the western gulf which will also keep precip chances going through day 7. As for now, will continue with scattered to numerous convection each day. Temperatures, while tempered somewhat by increased convection, will remain above normal through the week. The increased moisture will also keep afternoon heat index values from the upper 90s to low 100s. 01 && .AVIATION... 18Z Update... Expect better precipitation coverage today, and have indicated TEMPO TSRA for all TAF sites generally 20-00Z. MVFR-VFR cigs will continue, with some improvement this evening with diminishing precip before degrading overnight. IFR cigs and IFR-MVFR visibilities will move northwestward into the area from the south, with IFR cigs expected at KCSG, KMCN, and AHN. The Atlanta-area sites could see FEW-SCT low MVFR, but lowest cigs are expected to stay south of the KATL airport at this time. Will be dependent on rain today. Winds will be east, with a shift to the west possible after 00z Wednesday. Speeds under 8kt except near convection. //ATL Confidence...18Z Update...
