E PA/NJ/DE Winter 2025-26 Obs/Discussion

[rcostell]

Thanks for the clarification.  I was not aware of that. It seemed to me after a road is brined the road just stays wet and doesn't ice over until it get too diluted or washes off.

Brine lowers the freezing point of water… so roads “just stay wet” longer and lower temperatures… so your observation is correct, too.
