response from CT DOT:
The DOT said Wednesday morning’s weather event was “a perfect storm.” The agency said crews could not apply liquid pre-treatment for the ice because it was too cold Tuesday night. But it was also too windy Wednesday morning for crews to try to pre-treat the roads with hard salt, the DOT said.
“It was kind of this Goldilocks zone of ineffective options to pre-treat our roadways,” said Garrett Eucalitto, a deputy commissioner at DOT.

the liquid part I get-it would likely freeze up the nozzles on the machines-but too windy for rock salt? LOL
