.DISCUSSION...
MVFR ceilingxs (1,500 to 2,000 feet) will rebound by early to mid
morning. The wind forecast for later this afternoon has been
increased a bit, with a Small Craft Advisory being issued starting
late this morning into early this afternoon. It will likely be very
marginal and short-lived, but could see gusts up to 20 knots. Could
see showers, and perhaps even a thunderstorm this afternoon as well,
but not expecting any sort of severe weather. Can`t rule out a
lightning strike though, so will have a close watch on that all day.
Sunday will bring scattered showers and isolated thunderstorms to
sections of northeastern Maryland. This is mainly from the late
morning into the afternoon hours. Winds shift from northwest to
more northeast later in the day. Eventually east winds ensue late
in the evening which could bring another round of lower ceilings.
