PREV DISCUSSION. /Issued 409 AM EDT Sat Jun 12 2021/

.Morning Area Forecast Discussion for June 12.

SHORT TERM /Today through Sunday/ .

Current mosaic radar loop shows some isolated showers moving south across the state in the Northwesterly flow. These showers are dissipating and should be done with over the next few hours. Models are still showing a descent amount of moisture continuing across the area with the deep layer moisture remaining east of the state across the Carolinas. Have kept likely pops to mainly eastern and central sections of the state with the proximity to the better moisture and expected instability development. With the northwesterly flow setting up, slightly drier air begins to move in Sunday so expecting a bit less diurnally driven convective coverage Sunday afternoon.

High temps today and Sunday expected in the upper 80s to near 90 with lows in the 60s to near 70.

LONG TERM /Sunday Night through Friday/ .

Relief from the daily on and off rainfall is almost here. The long term picks up Sunday night, where HREF members show only a few remaining storms from earlier in the day over the CWA. One or two members do show the possibility of a self organizing complex of storms moving from the upstate of SC into GA, so did keep some PoPs around in north Georgia, though otherwise remaining storms expected to be into central Georgia by this time.

Global models continue to be fairly good agreement about the evolution of the forecast going through next week as can be noted by little spread in NBM forecast. Large ridge continues to build out over western CONUS under large anticyclonic PV anomaly undergoing a wave break early in the week while TPV is drawn into trough over the northeastern US. TPV embedded in trough combined with aforementioned wave break will dig the long wave trough down into the eastern US, bringing with it a cold front that should bring temporary relief from the humidity for a few days Tuesday into Wednesday. An initial surge of the front should happen on Tuesday, though it will likely stall a bit in north Georgia before another embedded shortwave in the long wave trough will help propel it through most of the CWA by Wednesday. This trough moves away by Friday, and with it our winds will switch back out of the south ahead of the next quickly moving trough, bringing with it a return of the summer humidity and rain chances.

Pops-wise, Monday and Tuesday will see scattered storms in primarily central Georgia, though certainly won't rule out a storm in the north given moisture still in place. By Wednesday, only isolated storms in far central Georgia, and not expecting much on Thursday. Chances of rain are expected to return by the weekend with diurnally driven showers and storms. Temperatures will be warmest on Monday and Tuesday ahead of the approaching front, with widespread 90s and parts of central Georgia surging into the mid 90s on Tuesday. A small cool down happens after this, bringing temperatures more in line with June averages in the upper 80s to lower 90s for the rest of the week.

The end of the longterm still contains the possibility of a tropical disturbance within the GoM. Piece of vorticity that is located within the Central American Gyre (CAG) is expected to shear off into the western GoM some point around the very end of next week, something that is shown by most global deterministic models and has substantial ensemble support in the ECENS and GEFS. Like yesterday, this is where any confidence ends. Ensembles paint a picture of developing tropical lows anywhere from the LA coastline to the Mexican coastline. As such, take any one model run with a grain of salt still, including those that show the system moving towards Georgia. More confidence about how any system may develop will come into next week, so stay tuned.

AVIATION. 12Z Update . IFR to MVFR ceilings across the area this morning. The lower ceiling will dissipate by 13-14z but may see some more MVFR ceilings with any afternoon convective activity. Will see some afternoon storms but not expecting as much coverage as yesterday. W to NW winds expected today with speeds 10kt or less. Will see some higher gust in and around any stronger storms this afternoon. Winds will turn to the NE after 06z Sun.

//ATL Confidence . 12Z Update . Confidence high on all elements.
