Here is the weather outlook for today and tomorrow and a look at the situation with Isaac. The projected paths of the storm have resumed their westward trend, so we still cannot be sure exactly where Isaac will come ashore and whether or not it will pass close by Macon County sometime next week.
Today: Patchy dense fog before 9am. Otherwise, mostly sunny, with a high near 81. Calm wind becoming north around 5 mph in the afternoon.
Hazardous Weather Outlook: A FEW THUNDERSTORMS WILL BE POSSIBLE ACROSS THE MOUNTAINS THIS AFTERNOON WITH THE PRIMARY THREATS BEING BRIEF HEAVY RAIN AND CLOUD TO GROUND LIGHTNING.
Tonight: A slight chance of showers and thunderstorms before midnight. Patchy fog between midnight and 3am. Otherwise, partly cloudy, with a low around 59. Calm wind. Chance of precipitation is 20%.
Monday: Sunny, with a high near 83. Calm wind becoming southeast around 6 mph in the afternoon.
Monday Night: A slight chance of showers after midnight. Partly cloudy, with a low around 62. Calm wind. Chance of precipitation is 20%.
