Cool, rainy weather developed in the wake of a cold front that slipped south of Ohio, dropping temperature into the chilly 40s, with periods of rain, after a couple of mild 60-degree days.
An upper-level disturbance will induce a surface wave over the Mid-Mississippi Valley tonight, which will follow the frontal boundary as it lifts northeast to near the I-71 corridor Sunday. Widespread rain will return later tonight, with a little wet snow mixed in northern Ohio. Rainfall totals are likely to range upwards of a half-inch during the day, before the rain tapers off late in the afternoon.
Behind this system, chilly weather will be around to start the holiday week, with lingering clouds and chilly highs in the mid- to upper 40s. High pressure will drift past Ohio Tuesday, initiating a return flow from the southwest that will pull moisture back into the state midweek. A storm in the southern Plains will cross Ohio Wednesday, with another rain event that will taper off early on Thanksgiving. Temperatures will be seasonal through the holiday period, with highs in the mid-50s to upper 50s.
