.DISCUSSION...
KEY MESSAGE 1...

Surface high pressure and northerly flow aloft will continue to keep
the area dry and cool for the remainder of today. Areas of fog will
be possible again tonight, particularly in sheltered valleys, along
with patchy frost expected in spots, mainly across parts of the
mountains in sheltered valleys.

The area should remain dry, cool, and mostly sunny through the
weekend, although a few clouds may appear from time to time
particularly across the east as low pressure slowly rides north
along the coast. In addition, a few light showers are possible
across the far northeast on Sunday afternoon/evening as moisture
spreads east of this low. Gradually warmer conditions take hold to
start next week as ridging builds in ahead of the next approaching
system, progged to affect the area by mid to late week.

.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
IFR or worse ceilings and visibilities are expected to develop

of the TAF period.
