KILM Morning AFD.. (Wilmington.NC)
1:30 AM this Morning..
KEY MESSAGE 4: Light wintry precipitation with minor accumulations
possible Sunday into Sunday night. At the very least, water
freezing on roadways could lead to hazardous travel conditions
Sunday night.
**Rates will overcome,, "cooling the Column"??
AND..
An arctic cold
front is expected to approach from the west Saturday
night before
likely moving through Sunday, although still some
uncertainty regarding exactly when. Meanwhile,
moisture will be
increasing across the region ahead of an approaching upper
trough. Rain will
likely start late Saturday night, although
should stay too warm for any frozen precipitation. However,
during the day Sunday temperatures could start falling inland
(especially aloft) depending on the timing of the
trough aloft
and surface cold frontal passage, which will lead to a bit
better risk for some snow to mix in with or even take over as
the predominant precip type. However,
moisture levels will also
be diminishing from west to east so the timing of deeper
moisture along with the sufficiently cold air will be crucial to
whether we see any measurable snowfall and/or any other types
of frozen precip. If the deeper
moisture departs but there is
still some shallow
moisture around we could see some freezing
rain/drizzle on the backside of the precip shield Sun eve,
mainly near the coast. The 01Z NBM still shows a moderate risk
for measurable snow (0.1" or greater) across much of SE
NC and
NE SC with the greatest chance near the
NC Sandhills. The latest
GFS ensembles continue to back off the risk for at least 1" of
snow (<20%). In any event, any wet roadways by late Sunday will
likely re-
freeze Sunday night as temps should fall below
freezing most places, so
black ice could make travel hazardous
into Monday morning (especially inland). Everyone is encouraged
to pay close attention to the forecast for early next week,
especially if they have travels plans.
Note: The last widespread measurable snow across our area was
January 21-22, 2025.
