Peak wind gusts will range between 20 and 50 mph Monday.

See an update from Meteorologist Marshall Downing below.

Rain has been steady through Sunday, and the rain continues for most until midnight. Our highest accumulations stay in Southside.

Steady rain continues through the evening

After midnight most of us dry out. Rain showers are unlikely on Monday, but the moisture available in the mountains leads to snow as cold air comes in from the northwest.

That snow, while generally light, continues to fall through much of the day. It takes until Monday evening for the snow to let up on our western slopes.

Light snow showers linger through midday with some snow into the afternoon

Most of us see between half an inch and 1.5 inches of rain. Snow is most likely where we have our lightest accumulations. The flood potential still exists particularly in our counties furthest to the southeast.

Rain totals are highest in Southside

Behind the rain wind gusts climb high. Before sunrise we have some gusts to 40 mph. With high winds possible through the day some of our most intense gusts could reach 60 mph.

Winds can gust to 40 mph as early as 6:00 AM on Monday

A High Wind Warning extends from Roanoke to the southwest. These counties are where gusts are likely to be highest, but counties in the Wind Advisory could get enough wind to break branches or cause outages.

Snow fall stays concentrated on northern slopes. That allows it to reach more than an inch in some spots. When paired with high winds that could mean reduced visibility.

Snow totals above an inch are possible to the north

The western slopes stay in a Winter Storm Warning through Monday with a Winter Weather Advisory in Grayson County. Snow stays further north than it did with our last system, but it’s still hard to spend time outdoors.

Rain totals could start to add up over the course of the day, and could lead to some localized flooding. In fact, most of the mid-Atlantic could see flooding today as lots of moisture is moving in from a storm system that developed in the Gulf of Mexico.

Local rainfall totals could near 3 inches in some spots. While other areas won’t see high amounts, any rainfall will help bring relief to the current drought. Try and stay dry out there today!

Rain estimates range from half an inch up to 3 inches

After the bulk of the rain moves through, winds will pick up. Tonight’s winds will be moving in from the north, and then eventually shift to be out of the west. That is when they turn gusty.

The timing of the wind shift is around midnight tonight. Gusty winds near 40mph ramp up and stick around through Monday and last into Tuesday.

Tomorrow morning will bring cold air as it funnels in from the north and west. Due to some left over moisture and lake effect, we will have the potential to see snow showers move into view, but mostly for the western slopes. A couple of flurries could make it over the mountains, but no accumulation is expected east of the mountains at this time.

Snow showers for the western slopes and mountain tops tomorrow

As mentioned before, winds pick up tonight and remain gusty until at least Tuesday.

The rest of Friday and through Saturday our weather stays calm, but Sunday brings heavy rain that can cause localized flooding and wind that could damage decorations or cause outages.

Shower begin moving in from both south and west in the early hours of Sunday. Showers are light as day breaks, but consistent clouds mean we don’t get to see much of that sunrise.

This rain is certainly helpful after the dry months in the second half of this year, but with some recent heavy rain the flood risk is higher. We are in a Level 2 risk for flooding on Sunday with the greatest chances closer to the Atlantic coast.

The flooding risk extends from South Carolina to New Jersey

Wind gusts between 30 and 40 mph arrive late on Sunday and linger into Monday afternoon. That wind could cause problems for holiday decorations or take away your trash can. Use Saturday’s calm weather to prepare for the high winds. Calmer weather by Tuesday gives you a chance to take everything back outside.

Thursday Night Update

Another system headed our way brings heavy rain early next week with most rain falling on Sunday and some lingering into Monday. Flooding chances are higher with this system than they were last weekend, but with warmer temperatures snowfall is less likely.

We stay dry through Friday and Saturday. The sunshine on each of these days helps temperatures climb into the low-to-mid 50s. Low-pressure systems join together south of us to bring moisture from the Gulf of Mexico inland as well as bringing Atlantic moisture onshore.

Most of this system stays as rain rather than snow
