Will skies be clear over southern Ontario Monday night?

Mostly clear skies are expected, with several exceptions:

-some low-level clouds may be over the GTA and western end of Lake Ontario during early evening due to a region of low-level moisture (illustrated below for mid-evening)

-some jetstream-level cloud may be visible over southwestern Ontario during the evening due to the jetstream winds moving eastward over southern Ontario overnight (jetstream-level moisture illustrated below for early evening)

-some mid-level clouds may develop over some regions after midnight due to mid-level moisture which is forecast to move eastward over southern Ontario before morning, ahead of Tuesday’s low pressure trough over the Great Lakes region
