Ice/Snow Event, January 28-29, 2014
A highly unusual, prolonged winter weather event unfolded over eastern North Carolina beginning
during the morning of January 28, 2014 and continued into the mid-morning hours of January 29. This
was an especially high-impact event for eastern North Carolina as many schools and businesses were
closed for 4 days due to widespread hazardous road conditions. This event was unusual in the large
accumulations of ice and sleet that occurred, in addition to significant snow accumulations over
inland areas (Figure 1).
The precipitation began as several hours of freezing rain over coastal sections of Carteret and
Onslow Counties. A few reports of up to 1/4 inch of ice were reported, especially in Carteret
County. The freezing rain changed to sleet during the mid to late afternoon hours near the coast and
started to work its way inland. With an initially very dry subcloud layer over inland areas, it took
several hours for the airmass to saturate and for precipitation to reach the ground inland. By late
afternoon, most areas were reporting a mix of sleet and freezing rain. By around 7 pm Tuesday, the
precipitation began to transition to snow over most inland areas (Figure 2) as a surface low started
to slowly gain strength and move well off the North Carolina coast. However, a pronounced warm nose
aloft (Figure 3) in the 7 pm (00Z) Newport/Morehead City upper air sounding, kept the precipitation
as a steady sleet over coastal sections through much of the night before transitioning to snow in
the early morning hours of Wednesday, January 29. The precipitation gradually ended by mid to late
morning on Wednesday.
With an accretion of freezing rain, 1 to 2 inches of sleet and as much as 7 inches of snow, roads
across eastern North Carolina became very hazardous. Numerous accidents were reported and most all
schools were closed from Tuesday through Friday. Temperatures below freezing and cloud cover kept
much of the snow and ice from melting until Friday.
