Creeping toward Spring

Now that we have crossed the winter solstice, the Northern Hemisphere begins its long, steady march toward spring. Too slow for many humans, the sun's angle will inch higher in the southern sky and, as a consequence, its rays will more directly impact the lands north of the equator. By the summer solstice, on or about June 21, it will reach its zenith (as our Hemisphere is at its maximum tilt toward the sun) and we will enjoy the longest day of the year.

Though our days will lengthen incrementally, we will not appreciate significant warming for another couple of months; in fact, at central latitudes of North America, the coldest days of the year (by average highs and lows) occur during the third week in January. While the sun angle will be too low to provide significant warming until mid February, we still enjoy balmy interludes as weather systems pump mild air up from the south.

Over time, the frozen ground will thaw, plants will germinate, birds will sing and our faith will be restored. Until then, we can enjoy the snowscapes, star gaze on clear winter nights, listen for the hoot of owls and dream of spring.
