More Weather Anomalies

It is Jan 10th (2012) and we are waiting for the bill chills. We saw about 15 below last week, but that was the roughest of the season. There is still time for the deep temperature plummets, but it is making me nervous (I’d hate to loose my bragging rights). The trend the last few years has been milder despite snaps in the last few years near 40 below. Apparently there have been revisions to the zone charting in the US, placing a lot of formerly zone 3 regions at 4. But since snow cover has been poorer and riddled with warmer spells, the likely cold plunges could be disastrous to growers. The irony is the new zone 4’s could be worse off than zone 2’s as regards cold damage to plants. Complicated isn’t it?
