For anyone who isn't familiar with Cheshire Gap showers, there's a
nice example today on the 1330 radar. The 15 minute animation showed
the showers running in a line from near the Isle of Man through the
Wirral and the Cheshire plain, down to Birmingham. The only other
showers in the region were isolated ones over the high hills of Wales
and the Pennines.

Incidentally, the showers were running precisely parallel to the
tightly spaced isobars shown on the 12Z and 18Z Exeter "fax"
charts.
