Hello folks! It's been a while. I am here with you right now to share that Thanksgiving will be a warm one. The first thing we'll look at is teleconnections. Teleconnections are essentially the positioning of high and low pressure systems and the way that the weather flows around them. Pretty much every teleconnection index is in a favorable state for warmer weather across the eastern USA. It won't be hot, it will just be warmer than average. First let's take a look at the PNA, a good teleconnection to use as it relates almost directly to the warm/cool areas across the country. The PNA will be in the negative phase at Thanksgiving. Negative PNA's provide warmer weather across the eastern US, as a ridge builds in the southeast. Here is a PNA forecast:
I have circled the area that I need you to pay attention to. If we look at this image, we see a very high chance that the PNA will stay negative for Thanksgiving. It looks to go more positive by the end of the month. Both the NAO and the AO are going to be positive, which also promotes warm air across the eastern US. Basically, everything is pointing to warmth. Now let's look at some true model forecasts. The next image I have is the temperature anomalies for Thanksgiving. These will essentially show how above/below normal temperatures will be for Turkey Day:
Pay most attention to the larger image in the top left corner. This is the ensemble mean, which takes all of the different solutions displayed in the smaller images and combines them into one. This particular image shows a lot of warmer air. If you look at the smaller images, you can see that they all show warmer air too. That is all I have for now, stay tuned!
