.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions are expected through this evening. There is the
potential for some lower CIGs to develop mainly over central VA
(near KCHO) late tonight into Saturday morning (FL010-020), with
spottier/briefer MVFR CIGs possible to the north during this
time. Winds will be become S tonight. Shower and thunderstorm
coverage looks rather isolated this afternoon, but felt the
potential was enough not just for thunder but also potentially
gusty winds in/near convection.
Sub-VFR conditions are likely over the weekend as an upper low
approaches from the west resulting in bouts of showers,
thunderstorms, and lower ceilings. Winds will maintain a
southerly heading through the weekend, with some marginal LLWS
possible at night as surface winds decrease and LLJs around 35
kts pivot overhead.
Expect frequent showers and/or t-storms Mon-Tue with periods of MVFR
cigs likely.
