.AVIATION /13Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions are expected through the weekend into early next
week. Expect SKC conditions with a few passing high clouds this
morning giving way to increased mid and high level cloud cover later
this afternoon and evening as a piece of energy moves through. This
piece of energy will touch off a couple of thunderstorms mainly west
of KMRB/KHGR/KFDK later this afternoon between 20-23z before
weakening further east toward KIAD, KDCA, and KBWI between 00-04z.
Did opt for PROB30s at KMRB, KIAD, and KBWI where confidence is
slightly higher for precipitation to occur, but may need to be re-
evaluated for KDCA pending model trends. Winds will remain light and
variable this morning before gusting out of the southwest at 15 to
20 kts this afternoon. Winds decrease tonight into Sunday.
Primarily VFR conditions are expected at terminals on Sunday and
Monday. An isolated t-storm could affect the northern terminals
Sunday (i.e MRB, HGR, FDK, IAD, DCA, BWI) that could cause temporary
reduced conditions at terminals. Once again confidence will be low
on coverage of t-storms with some focus across the Shenandoah Valley
and into southern parts of corridor late Sunday afternoon into
Sunday evening. Winds briefly shift westerly Sunday afternoon before
shifting south southeast on Monday. Additional t-storm chances are
possible Monday and Tuesday mainly at MRB and terminals points west.
A strong cold front moving through the region Wednesday and
Wednesday night could spawn numerous showers and strong to severe
thunderstorms that could quickly reduce ceilings and visibility to
MVFR and IFR in multiple periods of times. These conditions should
improve later in the week once the front is to our southeast. Winds
southwest 5 to 10 knots Tuesday through midday Wednesday, becoming
quite gusty within severe thunderstorms, then shifting overall
northwest 10 to 15 knots later Wednesday night.
