happ Posted February 4, 2011 Report Share Posted February 4, 2011 Freeze over. I hit 13F for a low which isn't that bad, but was far below freezing for 84 consecutive hours. That totaled up to 1,059.5 freezing degree hours. For reference the much briefer, but colder 1989 freeze totaled 1,125.2 freezing degree hours. Frond damage would have been worse in 1989, but the cold should have penetrated about the same distance into the trunks this week as 1989. From that standpoint this freeze was twice as bad as last winter's even though last winter we got a little colder. Unfortunately, the 1951 and 1983 freezes were about twice as bad as this. I don't think any palm could survive those without protection, and maybe not even with protection. In 1983 the lakes here had 7" of ice on them. Appreciate your documentation. Are you a weather spotter? If not, you might want to submit your data to the national weather service. This event had national impact that included sub-freezing temps as far west of the deserts of California, Nevada and Arizona and historic snowfall in the Great Lakes\ upper Midwest. It appears Texas was ground zero. Sorry that your palms suffered from this arctic invasion but from the perspective of a weather nerd it was fascinating watching this event unfold.
