Snow will be confined to the west-facing slopes through midday Monday. Aside from that, the wind stays gusting between 25 and 35 mph.

Wind gusts will peak between 25 and 35 mph Monday.

Highs reach the 30s and 40s, leading to improving road conditions in the mountains. Overnight lows bottom out in the upper teens and low-to-mid 20s.

Meteorologist Chris Michaels will show you where roads can be slick, how strong the wind is going to get and why we should care about high pressure this week.
Monday into Monday night will have a winter vibe to it.

Our Weather Authority Alert Day will expire at noon on Monday.


Sunday Afternoon Update

Our cold front continues to press east Sunday afternoon. The system used extra energy in North Carolina to develop storms which even prompted a Tornado Warning. Rainfall rates drop as Sunday continues.

Rain stays the main impact this weekend, but snow builds in northern counties Sunday night

As the rain eases off cold temperatures combine with available moisture to bring snow into our northern edges. That snow is light for most, but some accumulations of more than an inch are possible.

Temperatures are cool enough for some snow by 7:00 PM

Snow is barely falling in our region after sunset, and rainfall rates in Southside are lower than they were in the mid-afternoon. The main storm risk drops after 4:00 PM.

The NRV and Highlands have more consistent snow than rain by 10:00 PM

Colder temperatures spread the snowfall further east as the night goes on. Blacksburg sees snow by 10:00 PM with a mix near Lexington.

We begin drying from west to east after midnight

Precipitation in general dries out after midnight, but some snow continues to fall. With surface temperatures falling below the freezing point the leftover moisture from Sunday will begin to freeze and make for poor road conditions.

Snow wraps up Monday morning, but poor conditions on the roads can last longer

Light snow falls in the northern Highlands around sunrise with dry weather by noon.

Snow totals are limited past our western slopes

Snow accumulations are highest near Snowshoe with more than an inch possible on northern slopes in the NRV and Nelson County. Some snow in high elevations in both Floyd and Grayson Counties could reach more than half an inch.

Northern Pocahontas and Nelson Counties are in our Winter Storm Warning

We have a Winter Storm Warning in northern Pocahontas and Nelson Counties for the snow that builds overnight. These are where some of our highest accumulations develop. The Winter Weather Advisory in Grayson, Highland, and Greenbrier Counties show spots where snow might not reach an inch but is still enough to impact your day.

Snow will build on some northern roads, and cold temperatures through our region mean we could have icy roads

Whether it’s snow or cold temperatures most of us have poor road conditions early on Monday. Be careful of ice as you get back on the roads or even walking to your car. Warmer temperatures and consistent sun through Monday will help melt most of what falls, and our weather stays calm through the week.


Sunday Morning Update

A Weather Authority Alert Day is up for all of Sunday and extends until 12 p.m. Monday.

A marginal risk rides along I-81 today.

A couple of heavy showers and thunderstorms have the potential to grow and impact the areas highlighted above in green this afternoon. There is a low, non-zero risk or seeing a tornado this afternoon as winds pick up. If any storms do go severe, Your Local Weather Authority will be tracking them out for you.

Sunday 4:00 PM - Widespread rain becomes lighter, heavy showers in Southside

Widespread showers will persist through most of the day. By 4:00 PM, we start to see some deep pockets of heavy rainfall move through Southside, this is about the time the severe threat kicks in.

Sunday 7:00 PM -Cold air behind the rain allows for some snow showers to get going

By 7:00 PM we are seeing big time rain close to Lynchburg and Southside. A couple of these storms could clip our eastern zones. On the other hand, snow showers start to move in for the western slopes.

Widespread rain allows for accumulation to happen

Rainfall estimates could be as high as 1-2 inches for all counties today. Some spots will likely see even more than that as totals have the potential to be upwards of 3 inches.

Temperatures fall off quickly after sunset

Temperatures will be declining in the afternoon hours. Once the rain dies down and becomes lighter, cold air behind the cold front wastes no time moving in. This will allow for some of us to see flurries and light snow accumulation.

Monday 12:00 AM - Snow showers and flurries extend as far east as the parkway.

The overnight hours will allow for snow showers to get as far east as the Roanoke Valley and the parkway. The ground will still be wet and warm from showers earlier in the day, so snow accumulation that far east will be hard and is not expected at this time.

Limited areas see accumulation of snow through tomorrow morning

Areas highlighted in grey and yellow have the best chance of seeing flurries accumulate along the ground, or seeing a light dusting on vegetation. Totals could near 1-3 inches in some spots, especially along the mountains and high elevations.

There is also the potential for ice to stick on roadways in high elevations for the Monday morning commute. Above freezing temperatures return by noon for these areas.


Saturday Afternoon Update

The Weather Authority Alert Day has been extended through Monday, Dec. 11 at 12 p.m.

Saturday’s clouds precede rainfall through Sunday with some snow late Sunday into Monday morning.

See an update from Meteorologist Marshall Downing below.

Showers begin late on Saturday and continue through Sunday. Most rainfall rates are light through the morning.

Showers move in after midnight

Rain continues through the afternoon with some heavy rates and even rumbles of thunder. After 5:00 PM colder air starts making snow on our northern and western edges.

Snow begins around sunset

Showers continue in the east through midnight. Some snow falls closer to I-81, but warmer temperatures mean it’s hard for that snow to stick.

Rain totals are between one and two inches for most

Only a little accumulation is left by Monday morning. We dry out in the afternoon, but with cold air and plenty of moisture on Monday morning some ice could create poor road conditions.

Only a little snow is leftover by Monday morning

Rain totals across our region are high. Most of us get more than an inch of rain, but few locations get more than two inches.

Rain totals are between one and two inches for most

Since so much rain comes in a short amount of time flooding is possible in some areas. The main flood risk stays well to our north in New England.

Areas that tend to flood easily could be overrun Sunday afternoon

Snow builds up in the Highlands and NRV. An inch or more of snow can build on western slopes in the Highlands. Further south it’s harder for that much snow to stick at this point in the season.

Snow totals are highest in our western slopes

There are not many winter weather alerts as of Saturday afternoon. A Winter Weather Advisory is in effect in Pocahontas County for snow accumulations of multiple inches around Snowshoe.

Most winter weather alerts are outside of our region

Saturday Morning Update

Light rain is expected to move through Southwest Virginia today. Rain totals near a tenth of an inch for those who see a shower or two.

Saturday Rain Totals

The severe storm threat expands from the Mississippi Valley to the Tennessee Valley today. Parts of the NRV are included in this and could see a storm with heavy rain later on. Tomorrow, the threat pushes east and includes Southside. Similarly, the threat is the possibility of seeing a strong storm with heavy rain.

Storm Prediction Center Weekend Outlook

There is no doubt Sunday will be wet and feature plenty of rain. Rainfall estimates near 1-2 inches for all zones. A few spots could see upwards of that amount.

Roughly 1-2 inches of rain for everyone this weekend

After the rain moves through, there is potential to see snow showers after sunset and through the overnight. Most of these will be light and will have a hard time sticking and accumulating on the ground because of the soaking rain and warmer temperatures that came before.

Cold air allows for some light snow showers to get going around sunset.

Winter weather impacts are limited across the NRV, Highlands, and Roanoke Valley. To stay up to date on all things weather, download our weather app.

Snow Accumulation Possible Across The Highlands and NRV, Flurries-Dusting Elsewhere

Our next cold front brings showers late on Saturday that continue into heavy rain through Sunday with some snow possible Sunday night. We all could use rain to help our dry conditions, but high amounts come down in a relatively short amount of time.

This Weekend's Rainfall Amounts

Showers begin after sunset on Saturday leading to widespread rainfall by Sunday morning. Showers are relatively light in the early hours of the day with some moderate rainfall rates along and south of US-460.

Rainfall is widespread by Sunday 7:00 AM

In the afternoon, rainfall rates pick up. While the heaviest rain stays closer to Richmond, both Southside and Lynchburg get some impressive accumulations in just a few hours.

While rain is consistent through the east some snow begins to fall in West Virginia as temperatures fall. It takes a few more hours for that snow to reach our western slopes.

Some heavy rain is possible for parts of Southside - Sunday 4:00 PM

By 10 p.m., temperatures are cold enough for snow in the Highlands and NRV. Most of the system is done by Monday morning.

Colder temperatures allow for some snow after sunset - Sunday 10:00 PM

Snow accumulations are generally light, and with most ground temperatures above freezing, it will be hard for it to stick around. Western slopes could see more than an inch of snow with less as you get closer to I-81.

Snow accumulations are low in most spots outside of the Highlands

Once the front passes, wind gusts pick up with some reaching 30 miles per hour. This follows a pattern we saw with other fronts this season. Winds ease off in the afternoon and are largely calm by Tuesday.

Gusts pick up behind the front for each zone

After the front moves through, we have calm weather through the middle of the week.
