A strong arctic cold front will plow across the Mid-Atlantic on Tuesday, crashing temperatures below freezing from west (morning) to east (late afternoon and evening.)
TUESDAY MORNING – 4 AM TO 7 AM
The arctic front will each Southwestern Virginia early Tuesday morning. Rain will change to snow and temperatures will fall into the well into the 20’s and remain there throughout the day. Roads, bridges, and overpasses may become slick, especially if a heavier burst of snow develops across this area.
Wind gusts will increase across the ridges 25 to 35 mph with wind chills in the teens.
TEMPERATURES – 4 AM TO 7 AM TUESDAY
Across the Shenandoah Valley, temperatures will drop into the 30’s, but remaining in the 40’s across the Virginia Piedmont, it’s still a chilly rain with temperatures in the 40’s.
TUESDAY – 7 AM TO 10 AM
Snow continues across Southwestern Virginia, with the arctic front approaching I-95 corridor. A burst of snow could develop of the rain comes down hard enough. This will allow the colder air aloft to reach the surface and change the rain over to snow.
TEMPERATURES – TUESDAY 7 AM TO 10 AM
Temperatures will fall into the 30’s north and west of Richmond, with 20’s in the mountains. Wind gusts will increase across the Virginia Piedmont and Shenandoah Valley 20 to 30 mph.
10 AM TO 2 PM TUESDAY
As colder air rushes in with precipitation along the front, a burst of snow is possible across Central and Eastern Virginia. Ground temperatures are warm, but snowflakes will likely fly across the area. IF the snow comes down hard enough, a coating on rooftops, cars, and sidewalks will be possible, as temperatures fall into the mid 30’s.
There’s still a sun angle to deal with in November. If the precipitation is lighter, temperatures could warm to near 40 degrees.
2 PM TO 6 PM TUESDAY
The will reach coastal areas of the Mid-Atlantic by mid to late afternoon. Snow will mix with rain with temperatures rapidly falling from the 40’s and 50’s into the 30’s.
WIND CHILLS TUESDAY NIGHT
Low temperatures will range from the lower 30’s along the coast to teens in the mountains. Wind chills Tuesday night will be in the teens across Eastern Virginia and I-95 corridor, to as low as the single digits to near zero across the Shenandoah Valley and the mountains. Wind chill advisories are possible for the mountains Tuesday night into early Wednesday morning.
WIND GUSTS – TUESDAY & TUESDAY NIGHT
Strong southwest winds will switch rapidly to the north-northwest from west (morning) to east (evening.) Wind gusts will range 20 to 30 mph with higher wind gusts possibly up to 40 mph along the coast and in the mountains. Isolated power outages are possible.
Highs Wednesday will only be in the mid to upper 30’s in the Piedmont with near freezing temperatures in the mountains. Although the air will be very dry, a few Bay/Ocean Effect snow showers may try to develop and a few flurries will be possible along the immediate coast.
IF the rain changes to a burst of snow before ending east of the Blue Ridge, a small coating is possible, mainly on cars, rooftops, and lawns. The ground is VERY WARM, so it would take a burst for even a coating to occur, to drop temperatures into the mid 30’s.
Regardless, even if a coating doesn’t occur, many will likely see a period of snow before ending. It’s a reminder that this winter is going to be much different than the previous winter’s — likely lining up with 2013-14.
