While CIGs at most terminals are VFR, when showers pass through
they drop to MVFR. Northerly winds around 5-10kts through the
overnight.
Any lingering MVFR CIGs lift the second half of the overnight.
VFR conditions are expected Sunday, although northwesterly
winds increase again with gusts to around 20 kt.
A weak disturbance will pass through Sunday night which could
produce a few showers or sprinkles, but it is unlikely
ceilings/visibility are reduced. The next frontal system will
approach Monday evening. Showers are possible along with a few
thunderstorms...highest chance at MRB and lowest at CHO.
Westerly winds blowing 15 to 20 knots and gusting 20 to 30 knots are
