Our weekend went pretty much as described in our previous post, which did have the potential to be a bit troublesome. We had showers and storms both Saturday and Sunday - more numerous Saturday - but they were scattered and some got much more rain than others. More sunshine than expected both days sent our high temperature up to 90 each day before the rain provided a little cooling.
Overall, not too bad. The cool air did wedge into north Georgia on Sunday, keeping Atlanta and Athens in the 70s all day, but we stayed on the hot and humid side of the meandering front as expected.
The setup for this week is interesting. The old boundary is staying put, so the heat and humidity will stay around for a couple of days. Showers and thunderstorms will again be scattered Monday evening and a bit more spotty on Tuesday.
After Tuesday, we can pretty much take the rain out of the forecast, and the reason is that we'll have another cold front coming into play just as the old boundary washes out. This second front is a reinforcement of the cool air, but instead of providing a sharp break with summer heat, we'll have a gradual downturn in temperatures and humidity, and this time it will be accompanied by a drop in the dew points. Temperatures will fall into the 60s by midweek, and highs will ease down into the 80s leading up to next weekend.
So this is merely the first step toward real fall weather, and it will no doubt come as a relief compared to the rather extreme humidity we've seen of late as well as the 90-degree temperatures.
If that's not fall enough for you, at least one model is trying to place a trough over the eastern U.S. next week which would deliver some cool fall air deep into the South. Should the map displayed here verify and the pattern actually come to pass*, fall would arrive for real the middle or end of next week. I've always defined fall down here in Georgia as the first stretch of days with lows in the 50s and highs that remain in the 70s, or the lower half of the 80s with low dew points. When we get days like that, it almost always means we've made the jump and fall will be here to stay. Now that we're in the second half of September, it can't be too long in coming.
