... Patchy frost possible towards dawn Saturday morning...
A dry... cold Canadian air mass in place across the region combined
with clear skies and light winds will drive temperatures down into
the mid 30s in many of our valley areas overnight. As a result
patchy frost could develop towards dawn... mainly in our more
sheltered locations. It would be a good idea to protect any plants
which are especially sensitive to frost if you reside in the normally
colder valley locations.
... Patchy frost possible from late tonight into Saturday morning...
As high pressure built into the area today... the northerly winds
brought in some cool and dry air. The winds will diminish tonight...
and with clearing skies... temperatures will fall to the mid 30s in
the coldest valleys. This will allow for patchy frost to develop.
The frost will be limited in valleys where fog develops tonight.
However... in the normally colder valley locations... it would be a
good idea to protect any plants which are especially sensitive to
frost.
