A National Weather Service winter weather advisory will go into effect on the Peninsula 1 p.m. Thursday when temperatures are expected to fall near freezing and rain turns to a wintry mix.
The region could get between 1 and 2 inches accumulated snow and sleet by Thursday night, the advisory states.
With temperatures in the region in the neighborhood of 70 degrees Wednesday afternoon, Thursday's forecast may be difficult to believe.
Temperatures at the Newport News-Williamsburg International Airport reached 69 degrees and hit the 70-degree mark at the Norfolk International Airport, according to Lyle Alexander, a meteorologist at the National Weather Service office in Wakefield.
Temperatures Thursday will start out in the mid-40s and rapidly decline during the day. Rain is expected to change to a rain/sleet mix in the early afternoon, then to just sleet by the afternoon rush. Temperatures will fall below freezing by 5 p.m., the forecast shows.
Sleet will likely transition to snow overnight, and flakes are expected to fall through about 4 a.m. Thursday. The overnight low will be just 20 degrees.
The sub-freezing weather will be paired with high winds. Expect north winds up to 15 mph with gusts up to 25 mph, the advisory states.
After the system passes through, Friday and the weekend are expected to be clear, forecasts indicate.
Friday’s temperature will top out in the low 30s, and temperatures through the weekend are expected to reach into the 40s, with Sunday approaching 50.
