Where Has Our Russian Winter Gone?

The last three days the outside thermometer had been [1] showing a temperatures below -5 degrees. I was glad; it seemed to me that Lady Russian Winter finally had arrived. But last night when I have looked at the damned thermometer, I became really upset. The mercury in the column [2] went up to +2 degrees. It meant dripping water, slush, rime, and kissing and embracing cars on the streets again. I am afraid, I'll have to sell quite cheaply my skis and ski suit quite cheaply.

[1]  The past perfect tense is usually the best choice to indicate an event in the past (the thermometer showed a temperature below -5 degrees) that ended before another event began ("last night" the temperature rose.)

[2]  The column doesn't move up or down.  The fluid inside the column moves.  I assume the column is filled with mercury.  If you use something than mercury in the frigid northern clime, I'm unaware of that!
