Convection was very active yesterday here in Ireland, especially in the
afternoon, but the clouds didn't seem particularly deep for summertime. As
I drove out to the north coast around lunchtime, it was evident the tops of
CBs were being strongly sheared. Just checked the 12z Castor Bay ascent
and see strong speed sheer above 500mb (about 18,000 feet), with a maximum
of 127 kn at 315mb (~28,000 feet).

The 'MF' means "manual focus" and I can't turn it off if anybody can
advise how to turn off the display clutter from a casio qv3500 i'd be
greatful:
