UPDATED AT 4:30 PM TUESDAY
The sky will clear nicely overnight and then clouds return by daybreak on Wednesday.
ICE:
WHERE WILL IT DEVELOP? Western Greenbrier County, eastern Nicholas and all of Pocahontas County will begin to see freezing drizzle develop between 8-11 a.m. Wednesday. Most ice accretion will occur between 9 p.m. Wednesday and 3 a.m. Thursday.
WHAT WE EXPECT THE WEATHER SERVICE TO ISSUE: Winter Weather Advisories for eastern Nicholas, western Greenbrier and all of Pocahontas county for Wednesday into early Thursday.
TIMING, AMOUNTS AND IMPACT: Before it changes to all rain at 8 a.m. Thursday, about 0.20″ will accrete on powerlines and tree branches and 0.30″ will accrete on driveways, parking lots, walkways and the shoulders of secondary roads. The main thoroughfares such as Midland Trail, Route 219 and I-64 will stay wet. Expect scattered power outages; warming temperatures and lack of significant winds will keep outages from reaching widespread status. Allow extra time for the Wednesday afternoon commute, driving overnight and the Thursday morning commute. Expect the ice to melt by early afternoon Thursday as temperatures warm to 50 degrees.
FOG TIMING AND VISIBILITY EXPECTED: Dense fog will develop regionwide above 2,500 feet Wednesday evening and finally let up around 8 a.m. Thursday. Fog will limit visibility to less than 0.25-mi in eastern Nicholas, Pocahontas and western Greenbrier County overnight Wednesday (Dense Fog Advisory criteria). Lower elevation spots will also see reduced visibility of less than 1-mi between 2-7 a.m. Thursday.
RAIN: Drizzle will develop across the remainder of the region Wednesday morning. That will transition to a steady light rain after sunset and taper to showers after daybreak Thursday. About 0.50″ of rain is expected by late Thursday. This will lead to standing water in spots, but not as widespread as last Friday’s flooding.
