. Afternoon Area Forecast Discussion .

SHORT TERM /Tonight through Tuesday Night/. The short term period starts off with a cut-off low over NM/TX/OK, and near-zonal flow aloft across the CWA. For the rest of today, isolated light showers will be a possibility as moisture interacts with a cold front pushing through the area. Tuesday morning lows will be cooler than previous nights -- in the mid-30s to upper 40s.

The upper low will compress into a shortwave trough and traverse the ArkLaTex on Tuesday, continuing to advect warm, moist air across north and central Georgia ahead of it. PoPs will gradually increase from south to north on Tuesday as a surface low lifts northward out of the northern Gulf. Models generally have the axis of heaviest rain falling over central Georgia Tuesday evening through Wednesday morning. Storm total QPF for this period ranges from 2 to 3 inches along and south of a line roughly from Lake Harding (Harris County) to Forsyth (Monroe County) to Milledgeville to Wrens. Locally higher rainfall totals over 3 inches will be possible. At this time, it appears that isolated flash flooding should be the extent of any hydrological issues, as most river stations across central Georgia are measuring normal streamflows.

Only advertising a slight chance of thunderstorms for Tuesday afternoon and evening for now, given limited progged instability albeit decent bulk shear from the approaching upper wave. Highs on Tuesday will top out in the upper 40s to mid-50s. Wednesday morning lows will be in the mid-30s to mid-40s.

LONG TERM /Wednesday through Monday/. No significant forecast issues or weather impacts expected in the long term period. Heavy rain will have moved out by Wed morning with a period of dry, cool (near normal) weather following with NW flow aloft pattern.

Pretty good guidance agreement on next wave, expected to drop south of the area in NW flow on Fri/Sat. Mean flow somewhat weak but should move through in ~24hrs. Thermodynamic profile supports all liquid precip thru the event and little instability. Have no TSRA for now, but will continue to monitor. After this wave moves out another few days of dry, cool wx.

SNELSON

AVIATION. 18Z Update . Scattered -SHRA are ongoing across portions of north and central GA early this afternoon, and will slowly taper off this evening. Cigs are IFR (between 050-080) at all TAF sites (besides RYY, where cigs have been fluctuating between MVFR and IFR). Cigs will stay IFR through the first half of Tuesday. Meanwhile, winds will shift from W/NW to NE between 08z-10z Tuesday. SHRA will move into the metro Atlanta TAF sites from the south around 18z, with SHRA reaching MCN and CSG around 15z.

//ATL Confidence . 18Z Update . Medium to high confidence on all elements.
