The Weld RE-4 School District that runs Windsor schools has canceled Thursday classes.

The school district that was also closed on Wednesday attributed the closure due to "ground blizzards on county roads, intermittent power at some schools and inaccessibility to multiple neighborhoods."

All of the after-school activities in the district are also closed on Thursday.

The Weld RE-5J School District that runs Johnstown and Milliken schools has also canceled Thursday classes.

The Poudre School District that oversees Fort Collins schools, however, is planning to be open Thursday and follow the regular bell schedules. PSD officials also plan to monitor conditions throughout the night.
