Area forecast discussion...updated 
National Weather Service Peachtree City Georgia
755 PM EDT Monday Jul 28 2014



Short term /tonight through Tuesday night/...
broad trough over the eastern states continues to deepen into the
south. As a result...a surface front has pushed south of Atlanta to
Athens with drier and more stable air filtering in across north Georgia.
Ahead of the front...thunderstorms were currently developing in area
of very high cape and temperatures in the low to middle 90s. Storm Prediction Center has
issued a Severe Thunderstorm Watch for area just south of a Columbus
to Macon line. This area should gradually stabilize by early evening
as front continues to push south. Dew points will lower through the
night...with low dew points continuing through the short term.
Overnight lows may approach record min temperatures especially on
Tuesday night. Expecting a dry day across the entire forecast area
on Tuesday.

41



Long term /Wednesday through Monday/...
little change from middle shift Wednesday through Friday. Canadian high
pressure will continue to bring cooler and drier air to the region
through middle week before the deep wave trough axis shifts into the
area for the weekend. Northwest will transition to SW flow will increase
enough to lead to schc of thunderstorms on Thursday across the
area. This weekend a longwave trough is prognosticated to stall out over
the region. This could lead to heavy rainfall for the weekend. At
this time the GFS...European model (ecmwf) and gefs both hold the trough and SW in
place over the region this weekend. As we get closer to the
weekend we should have better confidence in possible heavy
rainfall.
