From DT after he issued his first call, I guess his map is invalid now. BIG CHANGES IN NEW SHORT RANGE MODELS REGARDING JAN 16
Full update on the Twitter page
But basically what's happened is that the new high resolution models coming in Friday night early Saturday morning or dramatically warmer at the mid levels of the atmosphere. This is producing a lot more sleet and freezing rain even in the Shenandoah Valley Southwest Virginia Virginia as well as the Virginia and North Carolina Piedmont regions and into central Maryland.
Fo example in central Virginia the temperature stays below 32゚ until 7 o'clock on Sunday evening which is quite a bit later than what the data was showing earlier.
The precipitation comes in with a lot of freezing rain and sleet in all of Western North Carolina the Western half of virginia into Western Maryland and even into West Virginia. The snow amounts on these short range models are reduced but the ice and the ice storm threat is dramatically increased .
If this trend is confirmed we are looking at much more than ice storm in the interior or Western half of North Carolina virginia of North Carolina virginia Western and central Maryland and West Virginia and a lot less snow. I'm not going to change anything right now but if the trend continues the last call map tomorrow morning will be significantly different.
