EASTERN N.C. - Several counties in Eastern Carolina are under a Winter Weather Advisory, due to the chance of freezing rain accumulation.
The advisory began at 11 p.m. Thursday for Edgecombe, Johnston, Nash, Wayne and Wilson Counties, and will last until 10 a.m. Friday.
Bertie County will be under the advisory from 3 a.m. to 10 a.m. on Friday,
Meanwhile, Duplin, Greene, Lenoir,Martin and Pitt Counties will be under the Winter Weather Advisory from 4 a.m. to 9 a.m. on Friday.
The Winter Weather Advisory means that a very light accumulation of freezing rain will be possible (about a hundredth of an inch).
Roads are expected to be slick and driving conditions will be dangerous, especially on bridges and overpasses.
Skies are clear late this Thursday evening, but that will change as we move through the evening and high clouds blow in from the West.
The bright 84% full waxing gibbous moon will be up there to brighten the night sky until it sets at 3:44 a.m. Friday.
By that time, we should be clouded up and some light rain will be trying to fall from the base of the clouds to the ground. The problem is that our lowest level of the atmosphere, right above the ground, is very dry. As the light rain falls into the dry air, it will begin to evaporate. That requires some heat from the atmosphere, and as the heat is used, the air becomes cooler and low temperatures should drop to around 30-34 degrees inland (west of US 17) as the air becomes wet enough to allow some light rainfall to make it to the ground.
That would lead to a five-hour window from about 4 a.m. to 9 a.m. for some patchy light freezing rain or drizzle to begin to accumulate on bridges and overpasses (from Hertford to Bertie to Pitt to Greene to Lenoir to Duplin Counties and areas west of those locations). With the threat of some spotty ice affecting the Friday morning commute, the National Weather Service has issued a WINTER WEATHER ADVISORY for the counties I listed above. Here is the text of the advisory.
INCLUDING THE CITIES OF...WILLIAMSTON...ROBERSONVILLE...
Closer to the coast, east of U.S. 70, the low will be 34-38 degrees and 38-42 degrees along the beaches. Those temperatures would support some drizzle or light rain.
Friday starts with clouds and the possibility for some slick roads for the morning commute in our inland counties, depending on what happens in the freezing rain situation overnight. But as the day goes along, the temperatures will get up to about 46 degrees, so the rain will be all liquid during the day. Friday should be cloudy with rain likely on and off through the day. The morning rain will be light, with heavier rain in the afternoon. The temps will likely rise just a little bit by late in the day.
