Special Statement
Issued: 8:43 PM EST Jan. 23, 2019 – National Weather Service

... Localized black ice occurring across some of the higher terrain
and colder valleys throughout central and northern Pennsylvania...

Pockets of cold, and slightly sub-freezing ground temperatures
are creating hazardous black ice as the rain falls on untreated
roads, bridges and walkways.

Use extreme caution while traveling overnight as car sensor
temperatures in the 30s to near 40 degrees won't be representative
of the much colder Road surfaces that could look wet, but be
coated with a layer of ice.
