The wind can do strange things. I have an airdata computer that gives a
constant display on winds aloft. Once I was flying into 130kt heawind out
of the East at FL290 with moderate turbulence. I asked for and recieved a
descent to FL250 and the wind was 35kts out of the West. I would have
thought it impossible. I have seen similiar shifts a few times but never
165kts of shear over 4,000'

Today, for the first time in weeks, dawned clear, cool, and calm. After
a VERY early spring (with temps in the 80s for over a week), we have
experienced extremely high winds and record COLD temps. In fact, we broke
the record here on both Sunday and Monday... (Take THAT all you "global
warming" pessimists!)

When we got to the hangar, the air was as still as death. The wind sock
hung limp as a rag, and AWOS was reporting winds variable at nuthin'...
Flight service mentioned nothing about turbulence (for a change) -- so we
taxied out to Rwy 25 in anticipation of a smooth ride to Clinton, IA...

Initially after departure all was smooth -- but by 1500 feet we were
getting bounced pretty good. By 3000, we were inside a popcorn popper.
Mary climbed to 7500 feet before we penetrated the haze layer, and popped
out into the clear, smooth air on top. It was a VERY uncomfortable ride
until then -- and, of course, she had to descend back down through it to
land.

On the return flight a couple of hours later, it was even worse. Now we
had heating of the day, with the sun on the dark, freshly plowed fields --
and the ride was wild, indeed. However, again it was smoother down LOW --
which was bizarre -- than it was in the middle altitudes.

I suppose after all the unsettled weather we've had the atmosphere is
still stirred up -- but no one standing on the ground would EVER have
guessed what was brewing and burbling just a few thousand feet overhead.
By all appearances, it was the perfect day to fly -- yet it was the most
uncomfortable flight we've had in a good long time.
