Nice Friday weather....
>> Friday, December 02, 2011
Above is today's edition of the Carolina Weather Video. Give it a look....
It's another cold start out there with temps in the 20s and 30s. However, highs will warm into the lower 60s for most today with sunshine all day. Pretty nice weather overall.
A weak cold front will slide through during the next 12 hours, but you will not even notice it is moving through. About the only impact is will have on our weather is to return our highs to the 50s tomorrow.
Next system....
Our next storm system will be a slow-mover, and there are still lots of timing difference amongst the models. Some modeling moves it in as early as later Tuesday (GFS) with other modeling (Euro) not until Thursday. Whenever the system does move through, look for some shower chances followed by chilly air.
Long-range...
One of the main components of my Winter Outlook was a general negative phase of the NAO and AO. Thus far, those indices have remained on the positive side. We will have one ingredient in place for cold air as we roll deeper in December, and that is a large ridge building near the West Coast. That alone would likely continue to provide us with some cold shots from time to time.
However, if you want to see a cold pattern lock into the eastern US, you really (in a La Nina) need the help of the NAO and AO. I still feel we will see these flip to negative at some point, but that is really just based off of the longer-term negative multi-year phase of the NAO we are in, and not based on anything I see in modeling right now. We will see.
