    VFR conditions expected during the early part of the period,
    however an upstream wave producing convection near KLAF will
    track through the area this morning. For the most part, expected
    the convection to be in a weakening state, so have opted for
    VCSH wording vs. VCTS, with confidence in thunder too low this
    morning. Another wave tracks across the region this
    afternoon/evening as a cold front tracks south into the area.
    This has a better chance to produce TSRA given daytime heating
    and the approaching surface forcing, however too uncertain at
    this point for pinning down the exact area, timing and coverage
    of any storms. Hope to have a better handle on TSRA potential at
    the terminals by the 12Z TAF issuance. Threat for TSRA/SHRA
    should end around or shortly after the 00Z-03Z timeframe.
    Westerly winds will persist into the afternoon, but will veer
    more northerly by this evening as the front moves through, but
    winds will be light at this point.
    
    OUTLOOK...Non-VFR possible for periods of time through Thursday,
    primarily centered around rounds of convection.
