1206 PM CST Tue Feb 16 2021

...Two rounds of Winter Precipitation tonight through early 
Thursday morning...

.The Wind Chill Warning will expire at noon today. The frigid 
cold that remains in place has hardened any ice that became

numerous areas of black ice on roadway and concrete surfaces. 
Another storm system will bring two rounds of winter type 
precipitation tonight through early Thursday morning. The first 
round tonight into Wednesday morning will bring freezing rain. 
This will bring renewed accumulation of ice on roads, especially 
those that continue to have ice from earlier systems. Through 
Wednesday morning, expect additional ice accumulations of 1/10 
inch over the warning areas with localized accumulations of 1/4 
inch possible especially across northern and eastern areas. The 
second round Wednesday night and Thursday morning will bring a mix
of snow, sleet, and freezing rain with some additional light
