Although it seemed unbearably late in the season for snow, the flakes that fell across DeKalb County came down weeks shy of the all-time record for the area's latest observed snowfall.
A low-pressure system with very cold air moved over the county Friday morning, Northern Illinois University meteorologist Gilbert Sebenste said. That cold air drop the temperature just enough to change the precipitation from rain to snow.
"Obviously it's snowing pretty hard now, but it will end at about noon as it moves off to the south," Sebenste said Friday morning. "Most areas will receive an inch or less on grassy surfaces, and almost all of it has already melted."
The latest snowfall on record was June 2, 1910, according to the National Weather Service in Chicago.
The snow had changed to rain before 11 a.m. Friday, and the only evidence it had snowed at all were the many photographs taken by stunned residents who looked out their windows and saw the green grass frosted white.
The weekend outlook looks better, Sebenste said.
"Just about anything is better than this," he said. "[Today] will be partly to mostly cloudy with temperatures around 60 [degrees], and Sunday we will be under partly cloudy skies and around 65 degrees."
Temperatures should be well into the 70-degree range by Wednesday.
"This won't last long," Sebenste said.
