Starting Sunday, we may also start to see the effects of Tropical Storm Isaias in the eastern part of North Carolina. If the GFS (American computer model) is correct, the storm may be off the northern coast of South Carolina by late Sunday, while the European model tracks a weaker system into the far eastern Gulf of Mexico before turning it northward. The GFS takes the storm through very quickly, and it is already gone by Monday afternoon; we would get very little from the storm.
However, the Euro track allows a lot of tropical moisture to get drawn northward by another trough and front pushing eastward through the Tennessee Valley. This could lead to a couple of days of rainier weather early next week before drying toward Wednesday. If this were to happen, we could end up with flooding and/or wind issues in the Triangle. At this time, it is too early to make that call.
