THREAT...Limited
TIMING...Tonight

HARD FREEZE
THREAT...Limited
TIMING...Tonight

Expect a mix of snow, sleet, and freezing rain to end before

ice and snow accumulations on road surfaces will be minimal but
expect many of these areas to continue to have slick roads, at
least on bridges and overpasses, through the afternoon hours.

In addition, very cold air is coming in behind the system getting
ready to depart the area. Lows tonight in many of these locations
will be in the upper teens after highs today mainly at or below

digits, at least for a brief period of time. This level of cold
will pose a hazard for people and pets without shelter and could
damage exposed and unprotected pipes.
