Re: Winter Wx Discussion 2014/2015
I noticed this too..pretty odd for that to bleed across the mtns isnt it??Math/Met wrote: This setup is aided by a Cold Air Damming type of flow in NC. This forces wind over WNC to have an easterly component, and this could cause convergence along the mountains over East TN.
Anyways... be fun to see how it plays out
Re: Winter Wx Discussion 2014/2015
The easterly wind component east of the mountains acts to “pinch” near the mountains where the air masses attempt to converge (along the inverted trough). This creates low level convergence and enhanced lifting. You could argue that there will be a slight upslope in the lowest levels on both sides of the mountain, which would force ascending air of course.
Here are the HRRR winds for later tonight. I tried to draw on this to give a better idea what we are discussing. Not the best graphic, but maybe it illustrates the possible scenario.

Re: Winter Wx Discussion 2014/2015
Snowing here with 27 degrees . Ground cover. 1 inch of snow expect. The 6Z Nam model is very bullish on snow for my area on Thursday. Just ck it at 5:10 A.M. and it show 4.6 inches of snow. One of our TV weathermen said I know models are difference but he said am telling you now it going to snow. Anywhere from 1 - 3 inches starting Weds evening. Very bold to say that. Most times they will say, we will have to keep an eye on it. Let hope it is right. If it right this should lead to at least a wide spread 2 - 4 inches...... As always it could change . Mts would get more if it is right.

2" exactly here (I measured). I'm half way to Karns from I-640 just off Western Ave.
Nice surprise getting that much snowfall.

Re: Winter Wx Discussion 2014/2015
I haven't posted much..... Works crazy! Anyways the models have been sniffing at the end of the month for a storm, can it be? Still about 8 days away, but the gfs is starting to show this thing again... Any thoughts?
