Saturday Evening Forecast Discussion - 9:35 p.m.

We are still watching things in the Gulf closely. The forecast changes on an hourly basis, but we are very confident that Alabama will feel the effects of Isaac Tuesday through Thursday, how intense it is, is still yet to be determined. The latest update from the National Hurricane Center is due out at 10 p.m.

As for the rest of the weekend, don’t expect much, if any, rain coverage on Sunday as a ridge axis builds across the lower Mississippi River Valley and toward West Alabama. This ridge combined with the effects of Tropical Storm Isaac will suppress activity through Monday. Highs Sunday and Monday will run in the low 90s with generally only high clouds across the area.

Attention turns toward Isaac for the forecast beyond Monday. Current NHC forecast track brings Isaac ashore near Destin and tracks north-northwestward into southeast Central Alabama by Wednesday morning. Outer rain bands could begin affecting far southeast Central Alabama Monday night, with rain chances increasing dramatically Tuesday and Tuesday night. Greatest rain chances, wind gust threat, and any isolated tornado threat will be across the southeast and then east central portions of the area. You should continue to watch the latest forecasts over the next couple of days as shifts in the forecast track and intensity of Isaac will play a significant role in conditions across Central Alabama. There remains a high level of uncertainty with this storm as models continue to shift their tracks and even a small shift or change in speed could be significant.
