Area forecast discussion, Dec 20, 3:03 PM EST, 1 hour 33 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 303 PM EST Wed Dec 20 2017 .SHORT TERM /Tonight through Thursday Night/... A frontal system is pushing southeast through the forecast area at the moment with areas across central GA seeing the rain at this time. This front should be completely through our area by 00z-03z Thu with just a few isolated showers remaining from the wrap around moisture around the back side of the main low center. as the front/low center move east of the state we will see a wedge of high pressure quickly build in across the CWA with the surface flow turning eastward over night. The wedge should remain in place through the remainder of the short term period but slowly weaken through friday night. this wedge will keep low overcast clouds over the state with temps ranging from the 40s for lows and 50s for highs. Will see some areas of fog over night and possible some drizzle during the day Thu. 01 .LONG TERM /Friday through Wednesday/... Moisture starts to return to the area on Friday in the form of light rain and some drizzle of ahead of an approaching frontal system. The bulk of the precipitation moves into the area on Saturday, although there are still some sigificant differences between the GFS and the European as far as timing. The GFS brings precip in on Saturday, clearing north Georgia by Sunday, shifting the deeper moisture to central Georgia before clearing our area in the overnight hours. The European is a bit slower, with the deeper moisture in north Georgia late Saturday, lingering precip across much of the area on Sunday before shifting further south and clearing the area on Monday. Decided to take a blend lingering chances for precip into Monday. Although precip chances start to decrease on Sunday night into Monday morning, there is still the potential for some locations in the northern portions of the area to see light snow with no accumulations expected. The rest of the extended should remain quiet. Temperatures through the weekend remain above average until Sunday, when the colder air starts filtering in and highs and lows will be below average over the next few days. Merritt && .AVIATION... 18Z Update... Frontal system going through the TAF sites right now so things are changing by the hour. light to heavy rain will be ending in the ATL area over the next few hours. will still see some light sprinkles through 00z but the rain should end by 19z-20z. Winds were out of the NW and have turned to the NE-E. Theses winds should turn back to the NW by 22z then turn back to the NE-E by 06z-08z Thu. The winds will stray out of the E through the end of the TAF period. Wind speeds are mainly in the 08-12kt range now but will see winds diminish to 9kt or less by 00z. Ceilings will stay mainly in the MVFR range through 00z then dip down into the IFR/LIFR range between 02z- 15z Thu. ceilings will lift back into the MVFR range by 16z Thu. VSBYs are up and down right now but should lift back into the VFR range as the Precip moves out. May see some brief periods of MVFR VSBYs over night with the LIFR ceilings. Will keep a close eye on this. //ATL Confidence...18Z Update... Medium confidence on all elements 01 && .PRELIMINARY POINT TEMPS/POPS...
