Bobbing Up And Down - But Not A Big Dive

Members of the CUDA club got together for a quick dip in the Tennessee River on Sunday. The water temperature was 74 which was warm considering the cool and breezy air temperature.
The cloudy skies made for a bit of a murky dive so Doug's headlamp probably lit up his dive very well. My dive buddy Ricky brought two lights so we could see the fish and other objects pretty well. To give you an idea of the visibility, the underwater shot was taken from about four feet away. (Which was a lot better than the near zero visibility a week earlier during River Rescue 2005)
More on this dive later.
We'll be bobbing up and down temperature-wise the next few days like we were bobbing up and down in the river. But the next drop in temps looks like a quick dip and not a big dive in numbers.
For example, while highs will be in the upper 70s to low 80s across the area through Friday, I would look for highs to drop into the upper 60s to near 70 this weekend. We should see highs around 74 these days. And overnight lows still don't go to frosty levels just yet. The average date of the first frost in Chattanooga is October 21st. And the average date of the first freeze is November 1st.
