070 FXUS62 KFFC 281935 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 235 PM EST Sun Nov 28 2021 .SHORT TERM /Tonight through Monday Night/... Large trough is located over the eastern CONUS with several embedded shortwaves within the northern and southern portions of the jet. Southern disturbance is currently responsible for very light echos on radar over central Georgia, most of which isn't reaching the ground. Some is reaching, however, so have maintained slight chance PoPs through the evening across central Georgia. Otherwise, cold front associated with northern disturbance in the jet is progged to move into the area through this evening bringing a reinforcing shot of cold air, with lows tonight down into the 20s and 30s CWA-wide. This front should push any remaining showers or cloud cover out with it. Tomorrow, biggest weather story will be very dry airmass in place leading to potential fire weather issues. Thin post frontal surface airmass will have very dry air aloft that should be able to mix down during the afternoon. This will bring gusty winds, though not likely strong enough to warrant full red flag conditions, and very dry air to the surface. See fire weather discussion section for more info. Lusk .LONG TERM /Tuesday through Sunday/... Mid and upper level flow will remain dry and northwesterly for the better part of the extended as strong mid level ridging remains anchored over the west coast. Will gradually see moisture return as surface ridging slides east Tuesday into Wednesday allowing for a slight southerly component to the wind and thus a slight increase in dewpoints through the week. Models start to diverge a bit by the weekend, but suggest that the west coast mid-level ridge breaks down by Friday allowing the flow across the US to become more zonal. Meanwhile a weak disturbance approaching by Saturday within the flow allows for the introduction of low end pops. Still some uncertainty in the model solutions with the ECMWF a tad wetter than the GFS for Saturday with the GFS a little faster to break down the ridge and a little dryer with timing differences on the approaching shortwave. Nonetheless, sensible weather will be running above average through the extended and mostly dry outside of the low end chances on Saturday. 30 && .AVIATION... 18Z Update...
