.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
While conditions will initially be VFR through this evening,
expect ceilings to drop overnight as a soaking rain overspreads
the entire region. Consequently, ceilings drop through MVFR to IFR
late tonight through early Wednesday morning and may remain
that way throughout Wednesday. However, a break of rain during
the middle of the day/early afternoon may allow conditions to
improve to MVFR. At times, visibility could also begin to near
IFR within the moderate to heavy downpours. This also comes with
increase east- southeasterly winds which will begin gusting to
around 20 knots by late Wednesday morning. Such wind fields
persist through the afternoon to early evening hours. Another
wave of moderate rain will likely arrive toward Wednesday
evening. Restrictions hold in place for all terminals into
Wednesday night, some potentially falling to LIFR at times.
As low pressure forms to the east near the Virginia coastline,
winds shift over to west-northwesterly on Thursday. Additional
restrictions are possible as well as more showers pass through
the area. However, do expect more breaks in the action, but with
isolated thunderstorms possible during Thursday afternoon to
evening. Continued west-northwesterly winds should gradually dry
things out into Thursday night. Depending on how much low-level
moisture is left, some return to VFR conditions is possible.
VFR conditions look probably to prevail Friday into the weekend in
post frontal northwest flow. Could see gusts around 20 knots Friday
morning into Friday afternoon. Scattered showers during the day
Friday could result in brief periods of sub-VFR conditions. These
showers come to an end Friday night into Saturday.
