Less humid air filtered into Ohio, as high pressure builds eastward across the Great Lakes, creating a northerly flow of dry, seasonably warm air.
A more significant warm-up will see readings climb back into the upper 80 and low 90s, as high pressure shifts to the Northeastern states. Winds will turn southerly, allowing more humid air to flow northward.
A few showers and storms could push into southwestern Ohio late Sunday, but the bulk of the moisture will remain off the south of central Ohio until Sunday night.
