First Fall Hard Freeze Climatology
Posted: 14 Dec 2011 05:48 AM
Having air temperatures at or below 28 degrees Fahrenheit are often
considered to be a 'killing frost' event. It is not an exact science
and very small scale processes occur to kill or protect the plant,
anyway the featured chart presents the the frequency of having such a
cold temperature by a given date in the fall season. For example,
Waukon has seen the first hard freeze roughly 70% of the years prior to
1 November. There is a variation of just around a month from the
earliest to latest in the state. In fact, Fort Madison made it till 9
December back in 2001 before hitting such a cold temperature.
