Cloudy skies and near normal temperatures will continue through
the weekend. The next widespread chance for rain will be on


Winter Weather Advisory through the night in the high elevations
of Preston, Tucker and Garrett Counties for freezing drizzle and
melting/re-freezing light snow. This will run through 6am, but
may be cancelled earlier as depth of moisture erodes and the
shortwave trough pulls away.

Elsewhere, winds will shift to the northwest in the wake of the
trough axis passage, bringing a more favorable fetch off of Lake
Erie and re-developing snow showers, mainly north of I-80. Any
accumulation through daybreak is expected to be light.

Did not go with anything higher than chance pops on Saturday
north of Interstate 80 with only shallow moisture present.
Overnight temperatures should be near normal around freezing with
daytime temperatures slightly below normal in the mid to upper


With high pressure around on Saturday night, there should be a
brief period of dry weather across the entire forecast area into
Sunday morning. Split flow continues to result in a difficult
precipitation forecast for Sunday afternoon and night. Have
continued with chance pops everywhere, although Pittsburgh has the
least chance of receiving any rain/snow with higher pops to both
the north and south. Any precipitation will shift east by Monday,
with high pressure once again bringing dry weather. Temperatures
will remain near normal.


As low pressure moves northeast, precipitation will move into
southern counties Monday night and everywhere Tuesday. The bulk of
precipitation will move east by Tuesday night. Although
precipitation is not expected to continue through the rest of the
week, it`s hard to determine any particular time that will be dry,
and have maintained low pops through the forecast. Timing of a
strong cold front remains uncertain for late week, but at this
point have gone with a high temperature forecast on Friday that
keeps the entire region below freezing.


Most terminals will maintain VFR ceilings in the mean through
midnight or so, although bands of snow showers may briefly drop
flight conditions into MVFR range. Ceilings will float down into
MVFR range overnight and mostly stay there through Saturday. Gusty
winds will continue to slacken through the evening, with west
winds under 10 knots pictured for Saturday.

Ceiling restrictions are likely through Saturday night in cold
W-NW flow. Restrictions are possible late Sunday/Monday, and
again Tuesday with low pressure.


MD...Winter Weather Advisory until 6 AM EST Saturday FOR MDZ001.
WV...Winter Weather Advisory until 6 AM EST Saturday FOR WVZ510>514.
