Every forecast across Central Ohio, highway-clear.
Official National Weather Service forecasts for Columbus and Central Ohio — ten counties inside and outside the Outerbelt, from downtown and Dublin out to Delaware and Newark, south to Lancaster and Circleville, and north to Marion and Mount Vernon.
Every Ohio region shares one system — the same maps, the same live radar, the same climate record. Columbus sits in the middle of the state with no lake to moderate it and no hills to break anything up, which makes it the plainest severe-weather setup in Ohio: the spring squall lines arrive off the Indiana line with a clean run. Winter is the freezing-rain line, and it sets up over the metro more often than anywhere else in the state.
