RMK: At 08z there was an extended blow (I'd hardly
call it a squall) from the NW lasting almost 5 minutes,
probably F 5-6 at its peak. At the same time the vis
dropped to 6km and there was a bar-kick of almost
1 mbar. No ppn, but we were beneath a line of quite
substantial AcCas elements at the time.
