In terms of this building--the flooding is too close for comfort. This too is standing water in Whiteside County.
WEATHER SNAP SHOTS
One of a number of beautiful shots of Saturday's prism-like array of colors on the high clouds which were in the area-a phenomenon known as a CIRCUMHORIZONTAL ARC. This shot was taken at Hassert Park within the Lockport Township Park District by Morgan Marie Williams.
Shirley Schaffer of Plainfield sent us this shot of the prism-colored circumhorizonalm arc she photographed on Saturday.
A sure sign of approasching warm weathre is the return of the brilliantly-colored circumhorizontal arc to Chicago area skies. This atmospheric phenomenon sometimes called a fire rainbow is caused by the refraction of light through the ice crystals in cirrus clouds. It only occurs when the sun is high in the sky, 58º or higher above the horizon, so at Chicago's latitude it can only be seen from about mid April to late August.
The American Meteorological Society's Glossary of Meteorology explains that the most colorful circumhorizontal arcs occur when the sun is at an elevation of about 68º above the horizon. The peak solar elevation Saturday afternoon was 64.3 degrees. Thanks to Mary Beth Turone of Romeoville and Rob Vaupel of Naperville for capturing these shots on Saturday afternoon.
