Will skies be clear Thursday evening over southern Ontario?
It looks like partly to mostly clear skies are likely over most regions. Some cloudiness is likely over regions approximately east of GTA, due partly to low-level cloudiness that may dissipate only gradually, and due to an area of mid-level moisture moving southward across Georgian Bay and central-eastern Ontario overnight. The chart below shows the forecast location of the mid-level moisture that may appear as some mid-level cloudiness (if the low-level cloudiness dissipates by sunset).
