AREA FORECAST DISCUSSION
National Weather Service Charleston WV
259 AM EDT Fri Apr 2 2021

.SYNOPSIS...
Upslope snow showers taper off this morning. Clear, calm, and
cold tonight under high pressure.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 250 AM Friday...

Overall, no significant changes to the overall forecast. Snow
showers are continuing to linger across the area early this
morning, and updated pops to reflect this. Still expecting
activity to generally taper off early this morning, along with
gradually clearing conditions, already being observed on
satellite. High pressure will nudge in from the west today,
along with much drier air taking hold. Relative humidity will
dip into the 20 percent range for much of the area this
afternoon. In addition, winds will continue to be gusty,
particularly during afternoon hours, before decreasing this
evening as the center of the high moves over the area, allowing
for a calm, clear night. As with previous forecast, undercut
guidance by a few degrees, and maintained freeze warning.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
As of 230 PM Thursday...

Friday night/Saturday morning may end up being the coldest of
this stretch with surface high nudging in for a much better
radiational cooling setup. I went a few degrees lower than the
coldest guidance as model soundings do not seem to be radiating
down as much as pattern would suggest...especially in the
hollows and sheltered valleys. Regardless, this will be another
hard freeze event with any vulnerable vegetation taking a hard
hit if left unprotected.

Surface high remains in control Saturday with low level WAA
allowing temperatures to moderate quite a bit during the day.
It will another cold night Saturday night, particularly in the
typical cold spots. Having said that, freeze headlines are not
anticipated though patchy frost is definitely in the cards.

Sunday will feature some low level moisture advecting southward
toward the area which will result in some stratocu as H85
temperatures back off a bit. Surface temperatures should still
manage to edge a few degrees higher than Saturday, especially
across the southern half of the area.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 235 PM Thursday...

The next chance for rain may arrive early next week courtesy of
retrograding upper low off the New England coast. There remains
some model variability on just how much impact this would have
on our area as some models keep much more ridging over the OH
Valley with any subsequent warm front remaining north of the
CWA.

&&

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
As of 125 AM Friday...

SCT -shsn through 10-12Z, mainly across north central WV and the
northern mountains, with brief IFR/LIFR conditions. After 12Z,
expect bulk of snow shower activity to diminish, and VFR area
wide. Otherwise, gusty northwesterly winds through 23Z, with
gusts in the teens across the lowlands, and 20-30 kt range
across the higher terrain. Winds will become light after 23Z.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY...

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS: Timing of end of snow shower activity and
associated restrictions may vary from forecast.

...A SNOW SQUALL WILL AFFECT CALHOUN...SOUTHWESTERN GILMER...
SOUTHWESTERN BRAXTON...WIRT...NORTH CENTRAL ROANE AND CENTRAL WOOD
COUNTIES...

At 1259 AM EDT, a snow squall was located along a line extending from
near Mineralwells to near Cedar Creek State Park. Movement was south
at 25 mph.

Winds in excess of 30 mph are possible with this squall.

Locations impacted include...
Parkersburg, Elizabeth, Grantsville, Gassaway, Mineralwells,
Arnoldsburg, Shock, Millstone, Cherry, Rosedale, Mount Zion, Little
Birch, Lucille, Davisville, Stumptown, Annamoriah, Frametown, Wilsie,
Palestine and Greencastle.

This includes the following highways...
 Interstate 79 between mile markers 51 and 59.
 Interstate 77 in West Virginia between mile markers 171 and 174.
 Route 50 in West Virginia between mile markers 7 and 8.
 Route 19 between mile markers 64 and 68.

Visibilities will drop quickly to less than a quarter of a mile in
this squall.

Use extra caution if you must travel into or through this dangerous
snow squall. Rapid changes in visibility and potentially slick roads
are likely to lead to accidents. Consider delaying travel until the
squall passes your location.

Temperatures well below freezing, in the lower to mid 20s, will also
lead to refreezing of melted snow on area roadways. Black ice is
nearly impossible to see and can also be hidden beneath snow. Please
use extreme caution, especially on bridges, overpasses and around
curves. Allow plenty of stopping distance and avoid braking suddenly.
