Special Weather Statement
With widespread temperatures in the 20s this morning, any
snowmelt or standing water from last night has likely become black
ice, especially on untreated roadways. Black ice is difficult
to see and makes roads very slippery. Slow down and give yourself
extra time to travel this morning.

Special Weather Statement
With a fresh snowpack and cold air advection behind the departing
storm, a cold night is on tap for the region. Temperatures are
already below freezing, and lows will bottom out in the teens to
low 20s late tonight. There may be some areas where winds can
become light enough for radiational cooling, and then even colder
temperatures are possible.
These cold temperatures will allow for any standing water to
freeze, especially on untreated roadways. Black ice is difficult
to see and makes roads very slippery.
