Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Winter Storm Warning for tonight through tomorrow morning.....
Snow initially this evening will mix and even change to a sleet/freezing rain mix as warm air comes in aloft (Over our heads). The mix will change back to snow by dawn with some additional accumulation likely. Ice accumulations of 0.1 to 0.3 of an inch will be possible along I-71 with snow/sleet accumulations of 3 to 6 inches. Areas well NW of I-71 will stay mostly snow, totals there will range from 6 to 10 inches. Areas SE of I-71 will see considerably lesser amounts of snow but higher totals in ice. Ice accumulations over 0.25 of an inch can cause problems with power lines and tree limbs. Ice accumulations of 0.5 is when huge problems really begin with tree damage and power damage. If you are in area outlined by these ice totals be ready for possible power loss.
During the day tomorrow winds will pick up out of the North blowing snow and drifting in some regions. Temperatures will really being to fall behind the storm into the single digits. High pressure will build in through early Saturday keeping cold air around. Another storm system will be possible Saturday night and Sunday.
