Snowy Springtime Timelapse

During this transitional season from winter to summer, as the sun travels higher in the sky each day and hints of summer’s warmth become more frequent, the weather responds to the nature of the season as well.  Often, here in the central Rockies of Colorado, there are days when still-chilly northwesterly winds are accompanied by frequent snow showers in the unstable atmosphere of spring—unstable because the atmosphere retains its cold memory from winter, while the land rapidly warms from the relatively strong springtime sun.  The following timelapse animation shows an example of this, with daytime heating causing snow showers to form and spread southeastward pushed by strong, cold winds from the northwest:

The timelapse compresses about 3 hours of midday weather into 33 seconds of video.  It was taken yesterday (29 March), and the camera was pointed to the south-southeast.  The images used in the animation were taken once every 20 seconds.  The location was just west of the Continental Divide in the Colorado Rockies.
