This is the 3-7 minimum average temperature differences. We definitely see the warm up intensifying, with 12-18 degree differences common throughout the Midwest and Plains. We do see the Rockies out west getting heat as the tight temperature difference lines are together. By now, there is a clear Jet Stream map that can come out of this. See the image below.
This is the forecast Jet Stream from the Weather Centre. I do predict the jet stream to be pushed north, letting in mild air. Below is the Day 3-7 Maximum Temperature anomaly.
Even though this is the maximum temperature average difference, the Rockies are less impacted by this. Now, there is definite evidence that in this 3-7 day anomalies, the Plains, Midwest and New England will be under a big thaw.
