Will skies be clear over southern Ontario Monday night?

Cloudy skies are expected by late afternoon and during the evening, caused by a low pressure trough and cold front moving eastward over southern Ontario. Following passage of the front, clearing skies are likely before dawn over northern regions of southern Ontario and near and east of the GTA as mid-level moisture moves south-eastward (illustrated below for early Tuesday) but southern regions seem likely to remain cloudy all night.
