Area forecast discussion, Feb 28, 3:09 PM EST, 7 hours 42 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 309 PM EST Wed Feb 28 2018 .SHORT TERM /Tonight through Thursday Night/... A warm front slowly lifting north across the area will continue to bring showers to the northern parts of the area. The heaviest precipitation should remain in the far north until this evening with the passage of another shortwave, where most of north Georgia could see some heavy rain, including parts of the Atl metro. After a brief lull in activity for many areas overnight and into early Thursday, a cold front will be pushing into the area from the northwest. The front will move through the metro in the late morning/afternoon time frame before moving through central GA in the evening. There is a marginal risk of severe storms for Thursday with the line. Even though instability is minimal, there is ample shear with the system...allowing for the potential for gusty winds with any thunderstorms embedded in the line as well as the threat of isolated, brief tornadoes. A flash flood watch is also in effect for far northern GA through Thursday evening. Cold front is projected to clear the area by late on Thursday. Winds will be strong on Thursday ahead of the front in central GA, with 20-25 mph sustained winds and gusts to near 30 mph. Winds will also be strong behind the front in the mountains with sustained winds 20-25 mph and gusts near 35 mph. High temps on Thursday will remain much above average, but with the frontal passage Friday morning temps will drop to the 40s across the area with 30s in the mountains. Merritt .LONG TERM /Friday through Wednesday/... The onset of the long-term forecast period will be characterized by dry and temperate conditions as high pressure builds into the region. While Friday will bring ample sunshine, breezy north winds will usher in cooler temperatures characteristic of early March. The sunny and dry conditions will continue through the upcoming weekend with afternoon highs ranging from the upper-50s in north Georgia to mid-60s in central Georgia. Low temperatures are forecast to be in the 30s areawide both Saturday and Sunday morning with some readings at or below freezing possible over portions of far north Georgia each morning. The next cold front will begin to approach the state by Monday night into Tuesday. Shower chances will begin to increase during this time frame, though discrepancies remain regarding the timing. The GFS remains a bit faster and weaker with the frontal progression as compared to the ECMWF. The front will be a quick mover and should clear the state by next Wednesday. RW && .AVIATION... 18Z Update... Light rain has generally cleared from the ATL area TAF sites for now with some scattered showers remaining in the area. IFR cigs will remain in the area until around 19Z-20Z, after which MVFR cigs are expected. A wind shift to the SW is forecast around 19Z- 20Z before returning to the SE around 0Z-1Z. Rain is expected to move back into the area in the 0Z to 3Z time frame before clearing start after about 06Z. Could see TSRA with the passage of the cold front between 17Z and 21Z on Thursday, with gusts up to 30 kts. //ATL Confidence...18Z Update... Low confidence on precip timing. Medium confidence on all other elements. Merritt && .PRELIMINARY POINT TEMPS/POPS...
