Temperatures are forecast to fall rapidly. Ponding water, slush, and any falling precipitation will freeze as the temperature drops.
Icy conditions Friday morning.
Following the passage of a cold front Friday morning, rain will change to snow and there will be a hard freeze as temperatures plummet. There may also be a brief period of freezing rain during the changeover from rain to snow. Snowfall amounts of up to 5 cm or so are possible Friday.
Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous. Take extra care when walking or driving in affected areas.
Flash freeze warnings are issued when a rapid drop in temperature is expected, that can cause water from rain or melted snow on streets and sidewalks to quickly freeze.
