SHORT TERM /Today through Sunday/.

Strong CFP leading the coolest airmass of the season so far is currently impinging upon the far NW CWA with waning intensity of associated convection. CAM consensus continues to have development with a diminishing trend this morning and have trended pops to where some scattered or isolated showers may make it to the I-85 corridor near or shortly after sunrise, then the vast majority of the CWA should be dry. Some very isolated redevelopment could occur in the far SE this afternoon and enough of an instability gradient to include slight thunder mention. Otherwise expect enhanced NW gradient winds really kicking in behind the front today and temps actually decreasing this afternoon. We should have the NW majority of the CWA about 15-20 degrees lower in the afternoon than yesterday, falling into the mid 60s for many locations aside from parts of central GA. With the expected sustained winds near 15 mph or slightly higher in some locations and gusts close to 25 mph today, Fire Danger criteria may actually be met as decreased precip coverage shouldn't affect much of the previously dry fuels. Overnight lows are progged to dip into the mid 40s for most areas and possibly near 40 or upper 30s for the NE mtns.

Sunday looks to be a clear cool day with still some NW gradient winds, though not as high/gusty and should be closer to 10 mph sustained with some gusts possibly up to 15-20 mph. Afternoon max temps will be limited to generally the mid to upper 60s north to low 70s south.

LONG TERM /Sunday Night through Friday/.

The longwave trough and associated surface front that brings gusty winds and cooler temperatures to the CWA this weekend begins to make its exit off the eastern seaboard at the beginning of the forecast period. A dome of high pressure builds in from the west resulting in fall-like weather at the beginning of the long term forecast. The gusty winds in the short term back off Sunday evening, but cooler than average temperatures persist. Widespread low temperatures in the 40s blanket the entire CWA with temperatures dropping into the upper 30s in areas of higher elevations through Tuesday morning. While max temperatures are still below climatology through Monday (max daytime temperatures in the upper 60s and 70s), a general warming temperature trend is exhibited through Thursday.

The benign weather in the first half of the forecast period comes to and end as a cut off low over the midwest develops and moves eastward, bringing a cold front into the CWA towards the back end of the long term forecast period. Global models (Euro/GFS/Canadian) diverge in their solutions over the strength and position of the parent low pressure as well as the amount of moisture available in the atmospheric column. The GFS is slightly faster with the approach of the frontal boundary while also having more moisture than the Euro or Canadian with progged PWATs <1.5". Given the nature of the uncertainty in the models, PoPs do return to the forecast Thursday evening associated with the frontal passage, but remain relatively low through the remainder of the period.

KAL

AVIATION. 06Z Update . Mainly initial VFR conditions, though a cold front will bring some MVFR cigs to KATL and nearby sites along with VCSH by 12z this morning. Brief IFR cigs are possible as well. KCSG looks to also have some MVFR cigs after 10/12z. Shower coverage should be diminishing shortly after and kept out mention for other southern/eastern sites. Initial SW winds swing west to NW later this morning with front passage and increase to 14-18 kts gusting 22-28 kts by late morning into afternoon. Expect clearing skies also by afternoon. NW winds continue this evening though lose gusts after about 01z Sunday.

//ATL Confidence . 06Z Update . Medium on shower coverage near KATL this morning. Medium on IFR cig potential this morning. High on all else.
