UPDATE: 3:30 p.m.

Lynchburg, VA – After looking and analyzing the very latest forecast models, both from the National Weather Service, and our exclusive in-house models, ABC 13 Chief Meteorologist Sean Sublette and the rest of the ABC 13 Weather Team will be ramping up snowfall total forecasts for many of you Thursday.

One of the main factors the weather experts have been looking at is the fact that virtually every computer model seems to be "grabbing" the storm in with good detail, and that tells the weather team that there indeed is a storm coming, one that could pack a punch by this time Thursday.

The timing of the snow still hasn't changed. The highest elevations will see rain turn to wet snow late in the morning Thursday.

From there, the New River Valley turns over to heavy wet snow by afternoon.

One main concern is that it appears the Roanoke, Bedford, and Lynchburg areas will likely change to snow as the sun is lowering in the sky. This allows the snow to stick – and the snowfall rates are expected to be high.

Road conditions and power outages are becoming a concern now.

This will be a relatively quick-hitting shot at snow, but it looks like there is enough moisture, cold air, energy and a decent track to forecast a winter snow storm for most of the area.

Winter Storm Warnings have already gone up for Nelson County.

Look for higher amounts from the ABC 13 Weather Team as well. We're almost finished fine-tuning our graphics for you and will have an update out as soon as we can!
