Weak high pressure over the western North Atlantic will continue
to promote mainly light to gentle east to southeast breezes
through the weekend. With the weakened pressure gradient across
the region, breezes may becoming light and variable for a time on
Sunday. Ample moisture remains in place across the region today
with leftover boundaries. These boundaries will be capable of
instigating new shower activity today with drier air filtering in
for tonight and Sunday leading to near nil rain chances. Min RH
values today will be near 60 percent both today and Sunday with
max RH recovering to the mid 80s percent overnight.
