KEY MESSAGE #1: Patchy fog early this morning. The overall pattern early this morning isn`t all that different than the past couple of mornings with plenty of residual low-level moisture in place. Additionally, light to calm winds are expected through the early morning hours. Thus, there will likely be some stratus and fog developing as we approach daybreak. Some localized dense fog is also possible, with the higher chances in the eastern Midlands and near bodies of water. Any fog or stratus that develops should dissipate by mid to late morning. KEY MESSAGE #2: Above normal temperatures through early to mid next week. A strong mid to upper level ridge is expected to remain over the area through the middle of next week, allowing for temperatures to remain well above average for the next several days. A passing trough to our north this weekend is forecast to briefly flatten the ridge. This may lead to slightly "cooler" highs for Sunday into early next week, but confidence is high that temperatures remain well above average. Guidance indicates that the ridge strengthens again for midweek ahead of another potential trough late in the week. Uncertainty in temperatures begins to increase for late week due to this. KEY MESSAGE #3: Chance of diurnal showers today into next week. With the abundant moisture in place (150-200% of normal), diurnal showers are possible beginning this afternoon and lasting through much of the week. However, with the ridge overhead, there isn`t much of a forcing mechanism to produce activity, so thinking any shower activity today and tomorrow will be isolated to widely scattered at best. The trough mentioned in Key Message #2 is forecast to send a boundary through the area Sunday, providing a better forcing mechanism that today or Saturday. That said, the boundary is forecast to be somewhat washed out, so forcing isn`t expected to be too strong. With the warmth and moisture in place, a few thunderstorms are possible, especially Sunday. The threat for severe thunderstorms is low, however. The diurnal chances for showers then continues through midweek ahead of the potential trough late in the week.

&& .AVIATION /06Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --
Not really much change in the moisture and overall pattern from what we`ve seen the past few mornings. Clear skies to start off the period will combine with light winds and plenty of moisture to help develop another round of morning stratus/fog across a good portion of the forecast area. Restrictions should begin to develop once again around 09z-10z as lifr stratus, with tempo periods of lifr visibilities possible through 13z-14z. The lowest morning vsbys are likely in the usual vulnerable locations of AGS and OGB. Improvement back to vfr then expected by 15z at all locations as mixing brings an increase in low- level winds. As for any rainfall potential, there is a batch of shower activity currently across central GA that is tracking northeastward towards the northern CSRA. However, majority of the guidance has this dissipating over the next few hours, so do not anticipate any activity reaching ags/dnl at this time. Later today, with a slight increase in moisture through the day, and inland moving sea-breeze, can not rule out an isolated shower during the afternoon, but confidence in coverage limits placing in any tafs for now. Winds through the period mainly out of the south. Either calm to light overnight, then between 4-8 knots through the daytime hours. EXTENDED AVIATION OUTLOOK...Patchy morning fog remains possible each day. Increased shower chances expected for the weekend and into early next week.
