  1. FYI, light snow has broken out in parts of the mountains, not depicted on any model. It could bode well for those downstream.
  2. The models keep showing a band of light snow blooming around 7 p.m. then moving east.
  3. The NAM's treatment of the surface low still looks very odd. Don't CAD setups tend to guide the surface low toward the margins of the CAD?
  4. Why is it that warm air can get in here and lower our snow totals but cold air never makes it over the mountains in time? Is it simply that the warm air has an easier time rising over the mountains and funneling in?
  5. I know we're talking about this weekend, but the models are also hinting at a winter storm next weekend.
  6. I won’t put much stock in these model runs until Thursday at the earliest.
  7. The cell just north of Pittsburgh looks like it has a TDS.
  8. What is that structure in the foothills, a mesolow? It keeps producing tornado warnings.
  9. Yeah, I headed out to the Bent Creek area for some mountain biking, but it started hailing just before I got there. I saw some miserable folks riding their bikes back to their cars while getting hailed on and said "screw that."
  10. A tornado outbreak -- including the threat of a few long-tracked, violent tornadoes -- is expected today into early this evening over the Southeast, especially parts of Mississippi, Alabama and Tennessee. Tornadoes, large to very large hail, and damaging winds to hurricane force also are possible over a broad area from the central Gulf Coast to the Ohio Valley and southern Appalachians. Not sure I've ever seen language that strong used to describe a situation in the Southeast.
  11. Are you telling me someone misinterpreted the data on Twitter?
  12. Here's a blue-hour blend photo from a lookout tower along the Blue Ridge Parkway (North Carolina, October 2019). Using a planning app (PhotoPills), I was able to determine that the Milky Way would align with my position along a colorful ridge line after dark. I took a series of blue hour photos to capture the foreground while it was still dimly lit by the fading twilight. I combined the data of these photos into one image that could pull out the color detail of the foreground landscape. When dark fell, I took a series of long exposures and combined their data in a program called Sequator. I brought the detail of the Milky Way out of the background using Photoshop, then I blended the foreground data with the night sky data for a composite. I used a Sony A7RIII camera body and a Sigma 14-24 f/2.8 lens, but you can get similar results with much cheaper setups. It's all in the processing. When I say "combining data," I'm talking about stacking, a process that aligns several images and averages out the data so that what stays behind is only the pixels that stay the same through the sequence. This eliminates transient objects, like hot pixels and thermal noise - the reason so many low-light photos look so grainy. The weather conditions were cool and clear, so clear that you can actually see a little airglow in the photo.
  13. Light rain in Asheville, but it's probably going to change back to snow.
