Long range forecasts in the 8-14 day range, encompassing much of Thanksgiving holiday, indicates a warmer than average scenario for most of the country. With a jet stream positioned far across the northern tier of the country, warm air should prevail south of that. Of course there will be day to day variation, but generally the long term should trend warm for most places, with the exception of the far west coast (likely due to frequent storminess).
At the same time frame, it appears the northern tier of the US (near the jet stream) will continue to run wet, and above average for precipitation. Meanwhile the southern and interior southwestern US will likely remain dry.
