.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
Prevailing VFR conditions are expected at the terminals today as
winds shift to westerly by this afternoon. Scattered showers
and thunderstorm are expected to form across the area this
afternoon, and TEMPO groups may need to be included to
advertise the thunderstorm threat particularly from DCA to CHO.
Chances for showers and a much lower end threat for storms will
linger through the night and into the day tomorrow. Lower
ceilings may also move into the area later tonight into
tomorrow. Most solutions show MVFR ceilings, but a few solutions
hint at IFR ceilings. These MVFR ceilings will likely linger
thorough tomorrow night before improvement back to VFR occurs on
Sunday. Winds will generally be light out of the east to
southeast on Saturday, and light out of the northeast on Sunday
VFR/dry conditions are likely Monday and Tuesday as light easterly
winds become southerly.
