A gust front rolls over open farm land ushering in a cold air mass and heavy rain.
On a visit to Northwest Ohio yesterday (May 30) I stepped outdoors, looked to the west and spied a beautiful sight… the ragged edge of a line of clouds in the distance.
I strolled out, beyond a treeline to get a better look and saw an impressive gust front running ahead of cold air rolling over the area! I quickly shot a series of photos of the scene using my iPhone but realized my big Canon DSLR camera was in the car. I quickly retrieved the Canon and returned to my vantage point.
Seeing how quickly the line was moving, I race-walked seeking a different view and shot a few more photos before rain drops warned me I’d better get to shelter.
Normally I drive miles to intercept phenomena such as this gust front but this time it came to me — a surprise but a convenience — saving me the trip!
A gust front rushes closer ushering in a cold air mass and heavy rain.
The night before last, the humidity of the past week finally blew away. The air is clear and light again and, when the clouds part, we can see lovely, deep blue sky in place of a hazy mess. This morning that deep blue sky played host to a nice display of whispy cirrus clouds. Taking an opportunity to pull into a park on during my commute, I spent a few minutes enjoying and photographing the sky with cirrus for decoration.
Addendum: An interesting photo was posted to the Palomar Skies blog… yes, the historic and world-famous Palomar Observatory! See: Palomar Flies its Colors! It turns out the technical name for this phenomenon is "circumhorizon arc." More on this may be found at: Atmospheric Optics.
