– Light Snow/Ice Event
Event Overview –
A fast moving frontal system
coupled with strong cold high pressure anchored over northern New England combined
to bring a quick shot of wintry precipitation to Eastern North Carolina
during the late afternoon and evening hours of Friday, January 25, 2013.
Surface temperatures across the region remained in the upper 20s to lower
30s through most of the day. As moisture increased ahead of a cold front
and a weak surface wave of low pressure moved just south of the region
(Fig. 1), precipitation moved into Eastern North Carolina and fell into the
shallow cold air mass, producing sleet, snow, and freezing rain from late
afternoon into the evening hours. Light accumulations of up to one half
inch of snow and up to one tenth of an inch of ice (Fig. 2) occurred over
the central and northern portions of the Newport/Morehead City CWA with
some sleet reported as far south as Richlands and
the Newport Area. Figure 3 illustrates the liquid equivalent of the event
with nearly four-tenths of an inch of precipitation across northern
portions to around two-tenths of an inch across southern areas. Severe
icing on the Neuse River bridge at New Bern caused as many as 20 traffic
accidents prompting the closing of the bridge during the evening.
Figure 1: A wave of low
pressure developed on a fast moving cold front along the Outer Banks as of
7 PM EST January 25, 2013. Cold air was supplied by high pressure over
Ontario nosing south over the eastern U.S., resulting in light wintry
weather across Eastern North Carolina.
