The weather geek in me was curious when Darold Gleason and I had a discussion about wind-driven current. That is a bass fishing term defined by surface winds that create current in the upper water column, from the surface down.
Wind driven current is a key influencer of stimulating baitfish activity on reservoirs without natural current, unlike manmade current as you have on power-generating lakes. In the latter case, anglers throughout the South know that when power is generated to create electricity, the bass fishing turns on and especially so during summer.
On Sam Rayburn Lake, there is no such scenario. Here, the wind-driven current pushes bass to ambush points, such as grass edges, windy-blown points and shorelines. When the wind blows, the bass knows which direction a meal is coming.
A little bit of wind here goes a long way.
"It doesn't take much," said Gleason. "When it rarely blows at all, like it has in the past few weeks, it can create bass activity."
Well, the anglers might just get their wish. A southerly flow of really humid air and hot upflow is creating thunderstorms training from the South and into central and east Texas. This screen shot shows the predicted pattern of precipitation for midafternoon.
If there were a wind-driven current forecast, I'd say there is a high probability of it coming into play this afternoon.
