The first time ever that we've cancelled a task just based on the
radar images.

This was the task that was called:

There was a sky full of left over clouds just after dawn. Later in the morning
these gave way to cirrus clouds that suppressed the lift.  As we approached
1 PM cu's began to form under the cirrus clouds and we had the best looking cu's
over the air field relative to the previous two days.

With good looking cu's Anna took off early but didn't stick.

I launched third after Bruce. He had pinned off early and was coming back to
launch again. Gregg pulled me almost due south and I pinned off in light lift.
There were plenty of cu's around me and I went under them to find 600 fpm to
9,000'.

There were soon five pilots in the air and getting high under the well formed
cu's. Then Belinda came on the radio. Cory and I and Bruce are the safety
committee and Belinda asked Cory and I how it looked to us. She was talking to
Bruce who was first in line to launch. Gary Osoba were looking at the radar in
their phones and it looked like there was a storm to the north northeast and to
our west and approaching us.

It looked good to us, as we could not see the tops of the cu's. We said that we
were doing fine and it was not up to us to cancel the day. Belinda took our
input and the radar images and canceled the task.

Later there was rain, at least at our hotel on the north end of Big Spring.
