.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions continue overnight as winds increase in the wake
of a cold front. West/northwest winds start out light this
evening before gradually increasing from west to east overnight.
Low-level wind shear may also be possible late tonight. Winds
gust 15 to 25 knots Wednesday morning across all terminals with
the exception being KCHO where light winds are expected. Winds
diminish Wednesday afternoon with light and variable winds
expected overnight. VFR conditions continue throughout the day
on Wednesday as surface high pressure builds overhead.
Cloud cover increases Wednesday afternoon with precipitation
returning to the forecast overnight Wednesday into Thursday. A
wintry mix may bring sub-VFR conditions to the metro terminals
with KCHO and KMRB expected to have rain. Restrictions are
possible through Thursday morning as precipitation moves through
the forecast area. Primary precipitation type will likely be
rain with temperatures right at or above freezing, although a
rain/snow can't be ruled out. Conditions improve Thursday night.
Friday will see plenty of cloud cover along with a wintry mix,
particularly north of I-66/U.S. 50. Lengthy restrictions are
looking likely as wintry precipitation falls amidst the low
ceilings. Some ceiling restrictions could continue into portions
of Saturday with moisture overrunning a boundary over the
Carolinas. By Sunday, rain overspreads the region ahead of a
strong cold front. Thus, expect additional periods of sub-VFR
conditions across the terminals.
