short term tonight through Wednesday night ...

the short term begins hot and dry as mid level ridging builds into
the area. At the surface, late tonight and into Wednesday, a weak
wedge looks to build into northeastern portions of the area as high
pressure moves east off the coast. As that happens, moisture from
the atlantic is also pushed into the northeastern portions of the
area. As a result, slight chance pops for showers and thunderstorms
have been included mainly across the northeast beginning Wednesday
afternoon.

Otherwise, high temperatures through the short term will generally
be in the 80s across the mountains, with widespread low to mid 90s
elsewhere, about 8-10 degrees above average.

Reaves
long term Thursday through Tuesday ...

only tweaks to the long term based on the latest guidance.

Hot temperatures are still expected for the memorial day weekend.

previous discussion...

the heat is still on through the extended forecast period. Record
500mb heights for may in the 594-595dm range still appear likely by
Thursday as the anomalously strong upper ridge builds in across the
southeast. While the 500mb ridge will flatten slightly into the
weekend, it will retain a firm grasp across the area with
temperatures continuing to soar well above normal through the
weekend into early next week.

At least some record highs will likely fall by the weekend with all-
time high temperatures for the month of may (listed below) still at
risk of being breached. Signs of any weakening of the grip of the
ridge hold off until at least Tuesday-Wednesday of next week at the
earliest with the GFS more bullish on this prospect.

Unsurprisingly, precipitation will be more or less nil under the
influence of the ridge with only limited shra tsra chances in the
northeast ga mountains Thursday afternoon.

All-time record highs for may:
atlanta: 97 degrees f in 1914 and 1941
athens: 100 degrees f in 1918 and 1926
columbus: 100 degrees f in 1916 and 1937
macon: 99 degrees f in 1898, 1953, and 1967

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.
