Area forecast discussion, Jul 8, 7:43 PM EDT, 1 hour 9 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 743 PM EDT Sat Jul 8 2017 .SHORT TERM /Tonight through Sunday Night/... Current radar loop shows showers and isolated Thunderstorms developing across the CWA this afternoon. The main line of storms associated with the frontal boundary is located NE to SW just north of the ATL area. For today and Sunday afternoon the models are showing decent cape values in the 2000 to 3000 J/kg with some shear noted as well. The better instability moves south tomorrow along with the frontal boundary and the associated storms. Expect some storms to become strong to severe mainly north today and central Sun as the frontal boundary sinks into south Ga through Monday. The main threats with any storms through the short term will be gusty winds, frequent lightning, small hail and heavy rain. Temperatures will remain near normal through the period. 01 LONG TERM /Monday through Saturday/... No major changes to the extended forecast needed. Old frontal boundary will continue across portions of central Georgia through the early part of next week. Even though the boundary should be very weak and a trough by this time, a convergence zone will remain. In addition, a shear axis aloft will remain situated just near the boundary. The slightly drier airmass across northern GA, north of the boundary, should begin to erode late Monday or early Tuesday. Typical summertime high humidities and hot temperatures will be the rule. Thunderstorms will have plenty of fuel to work with and are expected each afternoon and evening through the week. Heat Indices will begin to creep up near 100 degrees by the middle to late part of next week. Values may approach Heat Advisory criteria across the SE portion of the outlook area beginning Thursday. NListemaa && .AVIATION... 00Z Update... Overall weakening trend in the showers and thunderstorms over the last hour or so. Have a TEMPO going for all sites except CSG thru 01-02z. Thereafter could see a few lingering showers before clearing takes place. VFR conditions /aside from brief thunderstorms/ are expected for a good majority of the evening and overnight hours. Some patchy fog and isolated MVFR/IFR cigs are not completely out of the question around sunrise given the humid airmass...however confidence is too low to mention in the TAFs. A frontal boundary should keep northern sites dry tomorrow...with a PROB30 for TSRA covering CSG and MCN where the more unstable air will reside. Winds still on the west side...though could briefly flirt with slight NE around sunrise...but speeds should remain well below 10kts. //ATL Confidence...00Z Update... Low on MVFR/IFR cig and fog potential. High on all other elements. Kovacik && .PRELIMINARY POINT TEMPS/POPS...
