This is how my passenger side car window appeared at 7:30 am on Sunday, November 13, 2022. The air temperature at the time was 19 degrees F. To create these shapes, water from the air lands on a really cold surface (in this case the window), and its molecules freeze and join together with other water molecules to form patterns of ice crystals. The hydrogen and oxygen atoms form a hexagon shape. If water molecules run into something like a speck of dust, salt or washer fluid, they may change direction and branch out into different feathery shapes. iPhone 11 camera.

Aftermaths in weather conditions influenced by cold fronts following warm spells in the month of November are considerably different from their summer counterparts. Such was the situation on Thursday, November 10, 2022. By midday, temperatures had risen to the low 70s. However, the threat of approaching storms moving about 35 mph along a cold front was expected to change the summer-like conditions dramatically. The image above looks northeast from 33rd Avenue and 12th Street SW in Cedar Rapids, Iowa at 2:09 pm CST. The advancing line of the storms can be seen on the horizon.

2:30 pm. Looking west. Line of storms (above) are not looking particularly structured or visually appealing despite looking rather impressive on radar (below).
2:38 pm. Rain, wind and lightning (and dropping temperatures) almost upon me. Temperatures had dropped to about 57 degrees by this time.
2:46 pm. Looking northeast. Heavy rain (and temperatures) falling. By 8:00 pm this evening, temperatures had dropped to a chilly 40 degrees. Rain persisted through the night and changed to crusty ice by morning. By 9:00 am Friday, the temperature had bottomed out at 22 degrees F--almost a 50-degree difference in just 22 hours! iPhone 11 camera.
