Ohioans checking the Columbus weather forecast today will need to be prepared for a multiphase winter storm. A developing storm will track east across the southern Plains to the Tennessee Valley, with a swath of accumulating snow from the southern Rockies to the Ohio Valley.
Snow will break out across central Ohio and spread quickly north to the US 30 corridor by midnight. Expect several inches of snow on the ground by the Monday morning commute — heaviest near and just south of the I-70 corridor.
A dry Sunday provided an opportunity to do some holiday shopping. The scenery has changed as snow blankets lawns and light displays, and creates potential travel difficulties heading into the Monday morning commute.
High pressure across the Great Lakes is feeding a stream of cold air south into the Ohio Valley, with temperatures in the low 30s.
A multiphase storm emerging from the southern Plains is meeting up with the shallow wedge of cold air, inducing snow overnight, mixed with freezing rain in southern Ohio. Accumulations will range from 1 to 3 inches, heaviest near and a little south of the I-70 corridor. Be sure to check for Columbus and Central Ohio school and business closings and snow emergency levels by county.
The bulk of the first round of moisture will be through the Columbus area by daybreak, with some spotty freezing drizzle tapering off by mid-morning.
