Subject: [nafex] strange weather pattern
Date: Wed, 30 May 2012 18:38:59 -0600
Does anyone have any insights into the following strange weather phenomenon?
Recently (I wasn't actually here when it happened) we had some cold
weather that was not exactly a freeze and yet did serious localized
damage. Some plants with very tender leaves (peppers, locust, grape,
mulberry, persimmon) had damage but it was sporadic. One plant might
loose all its leaves and yet a plant just a few feet a way would have no
damage or just damage to a few leaf tips. I can understand that there
might be currents of colder air that might do localized damage but you
would think that such a mild touch of cold, though it could damage
tender leaves, couldn't cause the kind of damage that a deep freeze
would and yet nearly all of my wild plum fruits were destroyed and they
were already at least a quarter inch in diameter. I believe most of my
bush cherry fruits were lost, though the Montmorency and chokecherries
didn't seem to suffer.
How can a touch of cold that is so light that it leaves many plants
untouched do such serious damage to fruits that are already fairly
large? The killer is that my thermometer says the low was 51!! (It has
been acting up a bit so maybe it didn't record the real low. The sensor
is on the ground in a sheltered spot. Could it really have been 51 on
the ground in one spot and cold enough to kill fruits just feet away?
This pattern has happened a number of years before. It is distinct from
a true frost. With a real frost all the leaves would have been lost on
all the tender trees. With this pattern many plants escape with no
damage at all or just nipping of the tips of some leaves.
Please help if you have any idea of what is going on. This pattern is
frustrating because it can happen even when the weather is fairly mild
and the weather report calls for lows that are above freezing.
