Sub-freezing temperatures overnight will cause untreated surfaces to re-freeze. Temperatures will fall steadily overnight behind a cold front. Overnight lows are expected to reach upper 20s and low 30s.
Across the region by the predawn hours a steady breeze from the north will dry out some surface areas late tonight. However…any standing water leftover on untreated surfaces is expected to freeze.
