Although it's still a bit chilly outside (yet not nearly as cold as it has been), I can see those first signs of spring rising from the ashes of winter all of the sudden. The air smells different, the days are starting to get noticeably longer (I got to drive home from work today at 6:20 PM to that once familiar orange-blue western horizon), and like
Liam said, the birds are slowly coming back. In fact I've already seen a few building a nest in the eaves under the roof at work.
The Weather Channel's extended forecast for the St. Louis area is calling for a steady warming trend over the next week and a half. That should take us well into deep February, with March just around the corner. And that pleases me greatly.
