.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
Lowering cigs through the night, but remaining VFR through at
least 18Z Mon. Then. MVFR to IFR cigs with wintry mix Mon
afternoon through 15Z Tue. When if precip changes to all rain at
some of the terminals remain uncertain.
VFR conditions are likely on Wednesday with weak high pressure in
control and light northerly winds. Potential for CIG/VSBY
restrictions especially over CHO as low pressure looks to pass
mainly to our south. However the exact track of the low will
determine exact impacts.
