LATE SUNDAY NIGHT WINTER STORM UPDATE: Well, new computer data coming into the weather office tonight not prompting any major changes to the forecast as of yet....one thing that has changed is that the onset of the snow may be delayed a bit from what I had described earlier this evening. Based on this new data, the snow is likely to hold off until late Wednesday morning, and it's possible we don't see the first flakes falling until sometime Wednesday afternoon.
So ultimately, what is the key to how much snow we can expect to fall over Central Virginia? Well, one problem we have to face if you're a snow lover is the fact that the cold ridge of high pressure centered to our north will be sliding off the coast. What then becomes critical is the ultimate track of the area of low pressure....is it just offshore? right along the shoreline? or does the low track more inland? This will be crucial in determining how far west and northwest the rain/snow line will move into interior Virginia.....the farther offshore that the low tracks, the more snow we are likely to see here in the heart of Central Virginia. I still think several inches of snow are possible before any changeover would occur, but a shift in track of the low further inland would end up bringing us more rain in Richmond than anything else.
I know there is a hunger to know exactly "how much" you might expect to see in your neighborhood right now...maybe you live in Matoaca, or Blackstone, Reedville, Short Pump, Midlothian or Ashland etc....I am confident we will get a more clear picture of the storm track over the next 24-36 hours and be able to give you a more specific "how much" to expect in your area. Stay tuned for more updates, and as always, thanks for watching! Have a great night! -ROS RUNNER. You can fine me on Facebook at facebook.com/Ros Runner NBC12 Weather.
