Curtain Fall (Blue Norther)


One fine, clear day in Grand Forks, North Dakota
a sky of peacock hue commenced to change:
from somewhere just above neck-craning height
darkness began.
Pellucid lightness turned to Prussian blue
along a line descending visibly
as if someone had layered darkling dye
in our fish tank.

That afternoon the temperature fell from 60F to 20F in three hours, and another 40F overnight.  The norther was so dry you thought you could hear the boards of the house creaking as they gave up their moisture.

The next morning, it got cold enough to mention.

(I find I've written about the same phenomenon as @TranquilityBase - impressive, wasn't it?  Mine was in the early 1970s, but I suspect they still happen.)
