Long line, maybe 100+ miles, of big storms in Brazil. We're deviating upwind, which happens to be left/west as we're heading north. Impressive light show. Winds are about 80 kts from the NW so we're about 40 miles(?) upwind of the storms.
Here's where it gets crazy - the storms had enough outflow to change the winds to the east at about 30 kts. Neither of us had seen that big a change. In lighter winds had we seen a 10-20 kt wind shift direction near a storm? Sure. But to see a thunderstorm mass overcome 80 kts and generate an upwind outflow? That was very impressive.
