Looks like it's about to be official, the coldest winter on record for parts of Florida.

For the period Dec 21 - Mar 18, Orlando had an average temperature 13.2°C. The climatological normal for the astronomical winter season (Dec 21 - Mar 20) there is around 17°C; the previous record coldest for that period was 13.8°C, set in 1957-58.

Interestingly, 1957-58 was the last time that eastern Labrador went through most of the winter snow-free with frequent above-freezing temperatures... until this winter. Must have been a similar long-wave pattern in the atmosphere that year. It was an El Niņo winter that season too.

Might be tempting to use that year as an analogue to predict what the spring might be like - though wouldn't place too much confidence in such a prediction. As time goes on and more variables come into play, we should see the patterns begin to diverge.

Gosh, I hope this spring/summer is not like that of 1958. That was a super lame year temperature wise. Sydney and Halifax didn't even brake 30° that year.

You mean didn't break 30. I'd hate to put the brakes on this trend we got going ;-)
