...Snow and Ice-Covered Roads, Black Ice Expected...
Snow and ice-covered roads will persist overnight, especially
across portions of northeast Kansas into northwest Missouri. The
highest snow and ice totals occurred along and northwest of a
line from Olathe Kansas to Trenton Missouri. Those traveling from
southeast sections of the Kansas City Metro area to northwestern
sections of the city should be prepared for rapidly deteriorating
road conditions, especially on secondary roadways.
Temperatures will continue to fall tonight into the single digits
and teens. Any remaining moisture resting on the surface in
liquid form will quickly freeze this evening, creating
potentially hazardous driving conditions. The black ice will
especially be prevalent along untreated, secondary roadways and
walkways. Exercise caution and slow down if travel is necessary,
including the evening and morning commute.
With breezy northwest winds, wind chills will be significantly
colder, with values between 0 to 10 below zero tonight.
