Good afternoon....If you are reading from upper east TN you probably saw your first snowflakes of the season. The teleconnection signals gave me the heads up for this little treat about two weeks before it occured. I blogged about this several blogs back in the blog titled Snow around halloween
The rain started mixing with snow here late last night and it snowed most of the night but the ground was way to warm for anything more than a coating. Freeze warnings are in affect for east TN tonight and it will stay quite cool of the night for the next few days....but a warmup looks to occur before our next significant cold front.
This cold front looks to sweep across the eastern US sometime near the middle of the month (Nov 10th thru the 16th) and I think that this strong cold front will pretty much start our winter season...there are other signs that suggest this also. Negative NAO blocking looks to get more pronounced up in eastern Canada around this timeframe and this will send a significant amount of arctic air into the eastern US.
We have already experienced a small taste of the -NAO/AO signal with the Baffin Block up in Canada as this is what caused the current Noreaster to run up the coast and lay a (historic for October) swath of snow down. The current pattern looks to wash out and then get even more pronounced when it builds back in. So if I had any outdoor house/yard work to do I would be doing it before it got too cold in the middle of November.
