The hottest March day on record is expected for all locations in northeast Colorado today, Saturday March 21st. High temperatures are projected to soar into the lower 90's for the plains and urban corridor, and 70's to 80's for mountain and foothills communities, easily breaking March records established during the preceding days this week. The highly anomalous heat, exceptionally dry conditions, and breezy winds for most areas will drive very high fire danger across the region, including into the foothills and high mountain valleys.
