First off, it looks like we're going to have great weather for this Thanksgiving and the travel days around the holiday are looking pretty good as well. Follow along with the maps below.
The first map show very little precipitation around the country. The only storm is over the northwestern US, and that's where the colder air is locked up as well.
Take a look at the second map, notice how the warm and cold air masses are well separated. It's mild over basically the lower southeast 2/3rd of the United States, with the really, really cold air in interior Alaska and northwest Canada.
The third map shows the jet stream flow, and notice how the temperatures follow the upper wind pattern. The cold air north of the jet, and the warmer air south. This is a fairly zonal, or quasi-geostrophic flow, which is mostly west-east oriented. Right now, through Thanksgiving, this pattern is continuing to bring cool/moderate temperatures and mainly dry conditions.
The last image shows a great Thanksgiving forecast with sunshine and highs in the lower 60s! Of course, it's still a week away and changes could happen, so as always - stay tuned!
