.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Generally MVFR conditions (CIGs) will persist through the
daylight hours. As low pressure approaches the region, rain
will continue to develop through this evening from west to east.
Rain will become heavy at times late tonight into the pre-dawn
hours Saturday AM, reducing CIGs/VSBYs to IFR conditions across
the terminals. Breezy conditions develop this evening and
continue into Saturday with gusts up to 20 kts at times
possible. Rain will begin to taper off from west to east by
daybreak Saturday but will linger for DCA, BWI, and MTN until
mid-AM Saturday. Drying conditions ensue Saturday afternoon as
high pressure regains control of the region. VFR conditions are
expected to return to the terminals by Saturday afternoon.
VFR conditions are expected Monday and Tuesday, although we will see
a pretty consistent deck of mid-high clouds throughout the day on
Monday, as an upper trough moves overhead. Tuesday remains dry and
less cloudy. Winds will be out of the northwest at 5-10 knots,
gusting up to 15 at times.
