Not since 1873 has it been this cold,
on this date, March 4th,
here in Chicagoland,
blame it on the polar vortex!
Our thermometer read -4° this morning, that's with a windchill of -20°.

| Diamond dust over Lake Michigan, Chicago |
Diamond dust has been in the air this bitter cold winter ~ tiny ice crystals falling from an apparently clear sky, when the temperatures are subzero. In sunlight, moonlight, or artificial light, the ice crystals glitter and shine like diamonds.
