[pct-l] Sucker Holes

[Steve Rolfe]

Sucker holes occur after a cold front has passed.  The down welling of cold
air dries out a parcel of air and creates clear skies locally for a few
minutes.  Following a sucker hole will be an up welling of warm air creating
relatively intense rainfall. For reasons I can no longer remember the period
of sucker holes is often about 20 minutes.  They are called "sucker holes"
by pilots because the pilot could be led to believe he/she is getting out of
bad weather and into good weather.  Typically following a cold front the
wind will be very breezy for period of time and then relatively quiet for a
period of time corresponding to the sucker holes.
