.DISCUSSION...
KEY MESSAGE 1...Showery conditions today through Saturday.
Areas of fog this morning which could be locally dense.

KEY MESSAGE 1 DESCRIPTION...
Surface low pressure exits across the Maritimes today, with a
trof extending back across the forecast area, while an upper
low begins to move south across the region. Showers will persist
across the region today, with the better chances across
northern areas. Could also have the slight chance of an
afternoon thunderstorm. The surface/upper lows vertically stack
across the Maritimes tonight into Saturday, slowing the movement
of the system. A disturbance moving around the Maritimes system
will rotate across the region Saturday. Shower chances will
persist tonight into Saturday. The system then exits Saturday
night into Sunday. Additional rain totals today through Saturday
will generally range from a tenth up to around a quarter of an
inch. Abundant low level moisture will support areas of fog
this morning which could be locally dense.
