SHORT TERM /Today through Wednesday/ . A cold front approaching the local forecast area today will bring showers and the potential for an isolated thunderstorm. Current radar imagery is showing showers moving across portions of northern Georgia with some lighter showers moving across the Atlanta metro area. Through the rest of the day today, precipitation ahead of the front is expected to expand southward and eastward, moving southeast across the area. Although instability is low with this system, an isolated thunderstorm still isn't out of the question but no severe weather is anticipated. The actual front looks to enter northwestern Georgia later this morning, sweeping southeast through the afternoon hours. Behind the front, winds will turn northwest bringing colder temperatures to the area.

Overnight tonight into Wednesday morning, just before precipitation is expected to end, temperatures will start to fall into the 30s across portions of far northern Georgia. These areas may see a rain/snow mix before a brief transition from rain to snow on the backside of the front. Overall, accumulations are expected to be light, generally less than an inch, with the best chances across the highest elevations, so little to no impacts are expected. With southwesterly flow ahead of the front, highs today are expected to be fairly warm in the 50s in the mountains with 60s and 70s across the rest of north and central Georgia, around 5 to 20 degrees above average. Overnight low temperatures across northern and western Georgia will be dropping into the 30s with 40s expected across the rest of the area.

Through the afternoon on Wednesday, precipitation is expected to come to an end as drier air moves into the area and high pressure filters in at the surface. As a result, temperatures on Wednesday are expected to be close to but just slightly below seasonal norms, with temps in the 40s across far northern Georgia with 50s across the rest of the area.

Reaves

LONG TERM /Wednesday Night through Monday/ . Extended models in generally good agreement through the majority of the period as short wave impacts the area. The long term period begins with drying conditions behind aforementioned cold front, followed quickly by increasing moisture ahead of the next weather-maker.

Forecast models have warmed slightly since yesterday's runs, but still show a lingering cold enough airmass over northeast Georgia to continue mention of rain or snow, or a mix in the grids. Temperatures warm nicely through the day Friday, and any accumulations are not expected to last. Winds pick up with this system, and could meet critical Advisory thresholds in the higher elevations.

Wrap around moisture could stick around over far northeast Georgia through mid-weekend, but otherwise, expect a nice weekend. An active weather pattern remains in place into next week, with another wetting rain forecast to impact the area Monday and Tuesday.

AVIATION. 18Z Update . Showers along the main line have become more scattered with dry air behind the front With winds from the NW. not expecting an increase in moisture . so left IFR ceilings at all TAF sites in TEMPO except KATL and KRYY where the latter is expected to clear to MVFR ceilings shortly. Light showers will move across the area this afternooon through the night . though uncertainty remains on how much moisture remains for any MVFR or IFR conditions with these showers.

//ATL Confidence . 18Z Update . Low to medium confidence on all elements

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
