HPC anomaly (variation of something) is indicating a drop in temperatures across the South in the upcoming week.
The below image is the maximum of how much temperatures will vary from average over the next week or so.
This is, as a summary, an exaggeration of how much temperatures could be above or below from the average.
We see the entire East US covered in some sort of below normal expected temperatures.
Below is the minimum of what temperatures could change from average over the next week.
Much of the cooler temperature areas have dissipated, even replaced, with above normal temperatures.
Remember, these are estimates, and this is the minimum of what they could change.
For best estimates, combine the two maximum/minimum graphs.
For the above graph, we can see, still, that below normal temperatures are evident across the Southeast.
Combined, it would be a very good guess for temperatures to take a dip throughout the South.
