Temperatures are expected to rise this week, and with the defrost of sorts police said they might resume their search for a missing LaSalle County woman.
Tanya Shannon disappeared earlier this month after a car crash in the middle of snow-covered fields.
"We're preparing to get going if in fact the weather gives us a break," LaSalle County Sheriff Tom Templeton told the Chicago Tribune.
The investigation for Tanya Shannon, 40, was put on hold Dec. 8 after several days of searching amid freezing temperatures.
Shannon was last seen riding home from a holiday party with her husband, 41-year-old Dale Shannon. Police on patrol found the totaled car with Dale Shannon dead inside near Seneca, about 80-miles from Chicago, early that Sunday morning.
Deputies responding to the crash found footprints in the snow leading away from the car and a single shoe they believe was Tanya Shannon's.
A report from the coroner's office indicated that Dale Shannon was legally drunk behind the wheel.
