Clear skies are expected over most regions, due to a high pressure ridge moving over southern Ontario, except for lots of high cloudiness over southwestern regions and the western Lake Erie area caused by a mid-level disturbance over the southern Great Lakes region.

Wednesday, 2 July 2014



It looks like clearing skies, with dissipating thunderstorms being a big variable as some cloud remaining from afternoon thunderstorms will be sinking but may take several hours after sunset. The forecast chart below indicates some mid-level moisture over southern Ontario during late evening and this may appear as cloud, or the cloudiness may dissipate by an hour or more after sunset. So, clearing skies overnight (sometime).

Will skies be clear over southern Ontario Tuesday evening?
It looks like mostly clear skies are likely and some clouds may be expected to appear over some or most regions, some of the time. Moisture will be present at middle-high levels in the atmosphere and may appear as clouds occasionally.
Dewpoint and humidity will be high at the surface and this will cause dew to form on optical surfaces exposed to a clear sky after sunset.
