    Predominate VFR conditions are forecast through tonight as high
    pressure remains over the region. A few showers may impact MRB
    this evening and overnight, but confidence in occurrence and
    impact is low at this time. Patchy early morning fog may impact
    CHO/MRB Friday morning with MVFR VIS in and around daybreak.
    
    An upper trough and associated cold front will near the
    terminals Friday afternoon and evening. Some strong to severe
    storms may bring periods of IFR/LIFR conditions as they traverse
    the terminals. Convection wanes Friday night with low clouds and
    fog a possibility. Afternoon/evening showers and storms will
    once again be possible through the weekend as the frontal
    boundary lingers nearby, with Saturday carrying the higher
    chances. This will increase the likelihood for episodes of sub
    VFR conditions.
    
    Intermittent sub-VFR conditions could be possible in association
    with any thunderstorms that pass through Sunday, Tuesday or
    Wednesday.
