We should resurrect this thread, as weather variance appears to have been increasing over the last 2 years. Has anybody run across any useful indexes? Averages can remain relatively stable (that's what they are designed for) while variance goes absolutely crazy. Memory is notoriously "fuzzy" ... but my grey matter believes that "extremes" in weather are up.
Extreme, as defined by AGW, are weather related events that only occur if history is ignored.
I am slightly seasoned, extreme hasn't yet happened in these here parts. That doesn't mean I like the current weather, it only means that my dad, at 94, seems to have observed similar patterns the last time it was cooling. He talked about a farmer digging spuds on Thanksgiving because it had been to wet to dig them earlier. The good thing for that feller is that it didn't get very cold. The bad thing for this feller is that next week does look a bit chilly for proper spud storage in the ground, in rows.
