PREV DISCUSSION. /issued 250 PM EST Fri Dec 6 2019/

SHORT TERM /Tonight through Saturday Night/ . Area of precipitation associated with the system to the west is starting to shrink up and shift more southeasterly as the short wave races off to the east/southeast and the surface low drops even farther southeast into toward the northern Gulf of Mexico. Still think we will see it hold together enough for likely PoPs along the Alabama/Georgia border this afternoon, but it looks like better chances shift south and diminish a little faster than the previous model and forecast grid trends. Hard to tell how much clearing we see across the area Saturday/Saturday night. Temperatures remain seasonably mild through the majority of the forecast period, however we should see a push of cooler from the northeast Saturday night/ Sunday morning as high pressures "wedges" down the eastern seaboard into the state.

LONG TERM . /Sunday through Thursday Night/ .

The long term with a strong wedge building into NE GA early Sunday morning. As southwest flow advects moisture over the wedge, chances for showers will increase on Sunday afternoon into Sunday night. Have continued with slight chance pops for Sunday afternoon with increasing chances Sunday night into Monday. Models show the wedge breaking down fairly fast Monday as deep southwesterly flow continues ahead of the arrival of a strong cold front. A large longwave trough will push a cold front towards the area on Monday through Tuesday with the arrival of the front late Tuesday into early Wednesday. For these time periods have continued likely to categorical pops mainly across northern portions of the area.

Overall, models have come into better agreement on timing of the front through the local forecast area but the GFS is slightly wetter than the ECMWF. QPF totals for Monday through Wednesday are currently around 1 to 1 1/2 inches across northern Georgia with totals less than half an inch further south. In addition, with little to no instability with this system, have continued to keep the precipitation as just showers. Early Wednesday there is the slight potential for a mix of light rain and snow on the backside of the front, but will be highly dependent on temperatures and available moisture. This potential will continue to be monitored over the coming days.

By Wednesday, the front is expected to clear the area and high pressure will build into the area at the surface, providing dry weather through Friday. After this, models differ significantly with the next system forecast to impact the area over the weekend, but overall have gone with chance pops for late Friday/Saturday until models show more agreement.

High temperatures on Sunday will be slightly cooler with the wedge in place, in the 40s and 50s across northern portions of the area to the 60s further south. Low temperatures Monday and Tuesday morning will be trending upward in the upper 40s and 50s. The warming trend will translate to highs as well with temps Monday and Tuesday in the 60s and 70s, around 5 to 15 degrees above average. Highs through the rest of the extended are expected to be mainly in the 50s and 60s with lows in the 30s and 40s behind the front.

AVIATION. 00Z UPDATE .

Light rain showers have progressed east of all the terminals and will therefore remove precip mention. Most of the light rain missed the sites this afternoon and resultant MVFR is no longer anticipated with the exception of MCN. It will be a close call though for the ATL area sites and prospects will need to be monitored for possible reinclusion in next TAF set. Otherwise, winds have shifted to the east and should remain there for the balance of the TAF period.

//ATL CONFIDENCE . 00Z UPDATE . High on all elements.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
