Updated winter weather alerts from the National Weather Service. Greatest threat of significant snow accumulation Tuesday morning will be focused over northern Va, with lighter amounts of couple of inches possible in the purple "advisory" areas later in the morning into early afternoon.
Another shot of winter weather will hit Virginia Tuesday. The previous post here shows where the advisories are in effect.
A strong arctic cold front will plunge across the state around mid-day Tuesday. We expect rain ahead of it over RVA during the early morning, but there could be a rapid changeover to sleet then snow as bands of heavier precipitation push southward. Heaviest snowfall on the order of 3-4" will be over northern VA, with 2-3" possible from near Charlotesville to south of Fredericksburg. Closer to metro Richmond, an inch or two will be possible 15-20 miles north, i.e. Hanover, Louisa, etc, with a dusting south.
Most of all precip. should end quickly by 2-3pm, with some hints of sun possible later in the afternoon. Our coldest temperatures of the day will occur between 11am-2pm, with a rise back up several degrees after the moisture moves out.
With the activity yesterday and this morning, tomorrow's forecast has been lost in the shuffle.
We'll have yet ANOTHER wave of moisture coming our way. This one will be tomorrow morning through midday. Air will be cold enough to our North for some accumulating snow but for us, it'll be mainly rain.
BUT, as the rain tapers off enough cold air will arrive for a brief changeover to snow before it ends. I don't expect much accumulating snow tomorrow in Richmond, but just North and West of town looks a bit different. Here's a map with the current snow forecast, through tomorrow afternoon. You'll notice Henrico's west end is right on the line, with an outside chance at an inch of snow.
It's another borderline event for us, with cold air and moisture in short supply. DC is a different story. I put 2-4" there but that could easily be higher.
Be sure to catch Jim this evening for the latest. The NWS already has a winter storm watch up in C'ville and DC:
Again: mainly rain in RVA but could end as some snow.
No big change to our forecast. Still looks like minimal icing through early afternoon in Richmond metro.
Counties to our NORTH and WEST could get power outages + icy bridges and overpasses. the MAJOR impact from this storm will be on I-81 from Augusta to Winchester and Hagerstown. Travel in NW Va is not a good idea today. All of Virginia will be above freezing by tomorrow morning.
*we are back on TV from 9-10am on NBC12 with more weather information*
Storm impacts map for Sunday. Conditions will get progressively worse the farther west of I-95 you are. Winter storm warnings from the National Weather Service are in effect through 7am Monday for most counties west of RVA. * Generally light icing is anticipated along and east of I-95 from a combination of early morning sleet followed by a transition to freezing rain, then rain by evening. Remember, travel conditions can rapidly deteriorate even with light amounts of ice. This area, the I-95 corridor, including RVA is under a Winter Weather Advisory through 7pm Sunday. * Areas west of RVA under the Winter Storm Warnings can expect slightly colder temperatures, probably in the upper 20s much of the day. This will lead to very icy conditions throughout the central and western VA Piedmont. * Areas generally north of a Charlottesville-Fredericksburg line, could see a few hours of snow and sleet before changing over to freezing rain during the afternoon, and 1-2" will be possible with as much as 3" over the northwestern part of the state. Our NBC12 weather team will be monitoring this storm with updates here and on TV. -Jim
Our updated forecast map for Sunday 12/8. Winter Weather Advisories are in effect for the metro Richmond area, with a brief period of sleet and perhaps snow quickly becoming all freezing rain Sunday morning through afternoon. Temperatures will stay in the 30-33 degree range most of the day.
Areas 15-20 miles and farther west of Richmond will have a longer period of sleet in the morning as well as slightly colder temperatures all day (27-31), which will make icing conditions much worse the greater distance west of I-95 you go.
Areas closer to Charlottesville and points west and north of there could see an inch or two of snow and sleet in the morning before becoming freezing rain during the afternoon.
Winter Storm Watches and Winter Storm Warnings were issued this morning, and they will take effect tomorrow morning through Monday morning. Winter Weather Advisories will likely be issued later today as well.
There hasn't been much change in the forecast. Sleet, freezing rain and an icy snow is expected from metro RVA to the West and North. Areas East and Southeast of RVA should be primarily rain. Timing will be around sunrise, and as the day goes on, any frozen precipitation around Richmond should turn to a chilly rain in the afternoon. We should even get breaks in the snow/rain in the afternoon.
Areas West of I-95 could stay below freezing through the day, which would cause problems on the roads, even in the afternoon. Still, if you have to travel tomorrow, the afernoon should be much better than the morning.
Andrew and I will be on with the rest of our NBC12 crew from 6-8am, and again from 9-10am tomorrow.
This is our forecast map for Sunday. Winter Storm Watches are in effect for most areas west of I-95 from Sunday morning through evening. Precipitation will begin around sunrise in the form of sleet and perhaps an icy snow, before changing to freezing rain by midday in RVA. Areas west of Richmond will stay as sleet longer before changing to freezing rain.
Here's a quick evening update on Sunday's storm potential. it looks like the air aloft could be cold enough around sunrise Sunday to support a brief period of snow at the onset of precipitation over RVA before changing over to sleet and freezing rain. This map gives you an idea of what we expect. Counties just west of RVA will be most vulnerable to significant impacts from the ice.
