@GaWx , I can't seem to find the data currently.. do you happen to know the amount of ice that occured for the CAE area in Feb of 1969?
On 2/15-16, CAE received a variety of wintry precip from 1.11” of liquid equivalent including 0.8” of IP/SN. So there easily could have been the better part of an inch ZR meaning perhaps a good 1/2” of damaging ice accrural on trees.
