Final Winter Outlook for Lynchburg, Roanoke, Blacksburg and Danville Areas 2018-2019

I did way too early outlook here and stated that we could see a rather cold and snowy winter. Because some other factors could change, I left it open ended where changes could be made to my initial thoughts.

So, did things change? 

Short answer is no. We still have a west based modiki El Nino that will likely be weak to moderate.  The  PDO looks to be positive and the majority of climate models show good jet stream configuration that lends to cold and stormy in our regions. 

What do the official mets say? 

The NOAA official outlook is normal temps. Many to most private sector mets are on board with a colder than normal and snowier than normal winter. (Look up Wxrisk, RaleighWx if you want two public access winter forecasts)

What is Normal for our region? 

Tempature data is accessable on the NWS Blacksburg but snowfall per region on a long term average:

Danville 10 inches. 

Lynchburg 17 inches

Roanoke 19 inches

Blackburg 22 inches. 

I am using long term because there were some data errors in the early 2000 and we also had some less snow winters in the 00-08 winters. 

Tempatures:

In general will be 2-4 degrees below normal for the winter. 

Snowfall: 

 125 to 200% of normal snowall. 

Danville 14-22 inches for the winter .

Lynchburg 20-30 inches for the winter. 

Roanoke 22-32 inches for the winter. 

Blacksburg 26-40 inches for the winter. 

These as based on regions-- you should have an idea if your place does better or worse. EG: higher elevations in Roanoke like Bent Mountain do better than the Valley Floor on Orange ave. 

Confidence Level: 

The last super big winter, 09-10 I was fully convinced we were on the way to a banner winter. There are a few subtle differences that knock my confidence down a couple pegs but still lend credence to a big winter being on tap. 

25% chance we come in under my snow totals. 

50% chance we end up in that range. 

25% we out perform what I predict happens. Right now, these numbers put us just outside a 10 winter for our region. If this pattern develops as maximizes potential, we could end up with a top 5 winter ever. 

Winter Development: 

We will actually have a pretty cold pattern starting next week and will last about 2 weeks.  There is a decent show we may see our first flakes of the winter. 

December may favor a chance or window for a snowstorm, like late month between the 20th and New Years Day. 

I favor the pattern setting up for our "heart of winter" by late January. Late January through mid February should be highest risk for cold and snow. 

March could go either way but the pattern on many models still look solid for chances for snow. 

3 comparable winters:

09-10- Big December snow storm, 2 minor events. 

January- Big storm late month then active first 2 weeks Febuary. Lynchburg had storms of 12.5, 11.2 and 8 inches. 

02-03

No BIG snow storms but numerous events of 3-6 inches from early December Forward with a near miss where 4 inches of sleet would have been 14 inches of snow in Mid February. 

86-87

New Years Day snowfall of 3-5 inches, Back to back big snowfalls on Jan 22 and 26 of 10-15 inches and then another 2 events in February 

There are other years that have similiar but not as simialir patterns that had less cold and snow. (06-07, 87-88)
