Cook County Forest Preserve District Supt. Arnold Randall speaks during a Forest Preserve District board meeting on Oct. 5

But financial storm clouds will keep gathering on the district’s horizon while leaders wait to hear if voters throw it a financial lifeline next year, district Supt. Arnold Randall told county commissioners on Thursday.
